43. Control Output Terminals

[CONTROL OUTPUT 1 - 16]

Relay make contact outputs.

All the contact outputs are of normally open type when shipped from the factory.

Each output can be converted into normally closed type by changing the internal jumper setting. (See "Operation of Power Feed Jumper and Isolation Jumper" on the next page.)

Each contact capacity is rated at 40 V DC for withstand voltage, and 2 mA – 300 mA for control current. These terminals are controlled by the SX-2000 Setting Software. (See the separate Setting Software Instructions, "Pattern Settings.")

44. Isolation Jumper [GND]

The supplied removable terminal plug is equipped with a jumper. When the jumper is attached, the [-] terminals of all inputs (1 – 16) are connected to the internal power supply. Removing the jumper disconnects and isolates these [-] terminals from this unit. (See "Operation of Power Feed Jumper and Isolation Jumper" on the next page.)

45. Power Feed Jumper [VCC]

The supplied removable terminal plug is equipped with a jumper. When the jumper is attached, the circuits of all control inputs (1 – 16) are powered from inside the SX-2100AI. Removing the jumper disconnects this internal power supply and thus requires that power be supplied externally to the circuit. (See "Operation of Power Feed Jumper and Isolation Jumper" on the next page.)

46. Control Input Terminals [CONTROL INPUT 1 - 16]

Photo coupler inputs. A current of approximately 2 mA flows when shorted, and the voltage becomes under 40 V DC when opened.

The input of 100 msec or greater is required to operate. These contact inputs can be isolated from the SX-2100AI unit by cutting the power feed jumper (45) and the isolation jumper (44). Each contact input when isolated is 40 V DC for maximum applied voltage and approximately 2 mA for the loop current. Since each terminal is equipped with a current limiter employing constant current circuitry, there is no need to limit current on the external equipment side. The [-] terminals of all control inputs are common. Use the SX-2000 Setting Software to assign functions to these terminals. (See the separate Setting Software Instructions, "Event Settings.")

47. Analog Link Output Terminal [ANALOG LINK OUT]

When the light shutoff function has been set, if the SX-2000AO is not operated for 5 minutes or more, the fluorescent display's light goes off and the standby indicator (11) begins to flash. Pressing any keys other than the function keys on the front panel resets the screen display.

- Normally, the fluorescent display's light goes off at the time of the power failure.

- While the SX-2000 system is in an emergency condition, the fluorescent display's light does not go off even if the power fails.

30. Emergency Indicator [EMERGENCY]

Lights when the SX-2000 system is in an emergency condition.

When the 24 V emergency cutoff input ^*2 is enabled, this indicator flashes if the input receives an emergency signal.

*2 The SX-2000AO has a 24 V emergency cutoff input terminal (49) on the rear panel, allowing control of an emergency audio input. When the SX-2000 system is combined with an emergency broadcast system, a 24 V DC is normally kept being supplied to this emergency cutoff input terminal and is cut off (24 V emergency cutoff function) in emergency situations. This interrupts the general-purpose broadcast from the SX-2000 system, allowing the emergency broadcast system to override it. (For details, see p. 56.)

Note

When the 24 V Emergency cutoff input is set to be disabled (not usable) with the DIP switch 8 inside the protective cover, the Emergency indicator will not flash even if 24 V DC supply to this input terminal is cut off.

38. DC Power Input Terminal [DC POWER IN]

Connect an optional DC power supply unit to this terminal. Select the DC power supply source with consideration given to the current power consumption of the system the SX-2000AO is to be connected to. When not using a redundant power system*, connect the [+] terminal of input A to the [+] terminal of input B, and the [-] terminal of input A to the [-] terminal of input B. (Refer to the Instruction Manual attached to the VX-2000DS.)

* A method of connecting separate power sources to each power input or connecting the commercial power supply and backup power supply separately to each power input to prevent the system from going down when a cable is broken or power fails.

39. Control Output Terminals

[CONTROL OUTPUT 1 - 8]

Relay make contact outputs.

Each contact capacity is rated at 40 V DC for withstand voltage, and 2 mA – 300 mA for control current.

These terminals are controlled by the SX-2000 Setting Software. (See the separate Setting Software Instructions, "Pattern Settings.")

40. Power Feed Jumper 2 [VCC]

The supplied removable terminal plug is equipped with a jumper.

When the jumper is attached, the circuits of control inputs 3, 4, 7, and 8 are powered from inside the SX-2000AO.

Removing the jumper disconnects this internal power supply and thus requires that power be supplied externally to the circuit. (See "Operation of Power Feed Jumper and Isolation Jumper" on the next page.)

41. Isolation Jumper 2 [GND]

The supplied removable terminal plug is equipped with a jumper.

When the jumper is attached, the [-] terminals of control inputs 3, 4, 7, and 8 are connected to the internal power supply.

Removing the jumper disconnects and isolates these [-] terminals from this unit. (See "Operation of Power Feed Jumper and Isolation Jumper" shown below.)

42. Control Input Terminals

[CONTROL INPUT 1 - 8]

Photo coupler inputs.

A current of approximately 2 mA flows when shorted, and the voltage becomes under 40 V DC when opened. The input of 100 msec or greater is required to operate.

These contact inputs can be isolated from the SX-2000AO unit by cutting power feed jumpers 1 (43) and 2 (40) and isolation jumpers 1 (44) and 2 (41). Each contact input when isolated is 40 V DC for maximum applied voltage and approximately 2 mA for the loop current.

Since each terminal is equipped with a current limiter employing constant current circuitry, there is no need to limit the current on the external equipment side.

The [-] terminals of 1, 2, 5, and 6 are common, while those of 3, 4, 7, and 8 are common.

Use the SX-2000 Setting Software to assign functions to these terminals. (See the separate Setting Software Instructions, "Event Settings.")

43. Power Feed Jumper 1 [VCC]

The supplied removable terminal plug is equipped with a jumper.

When the jumper is attached, the circuits of control inputs 1, 2, 5, and 6 are powered from inside the SX-2000AO.

Removing the jumper disconnects this internal power supply and thus requires that power be supplied externally to the circuit. (See "Operation of Power Feed Jumper and Isolation Jumper" shown below.)

44. Isolation Jumper 1 [GND]

The supplied removable terminal plug is equipped with a jumper.

When the jumper is attached, the [-] terminals of control inputs 1, 2, 5, and 6 are connected to the internal power supply.

Removing the jumper disconnects and isolates these [-] terminals from this unit. (See "Operation of Power Feed Jumper and Isolation Jumper" shown below.)

45. Audio Output Terminals [LINE OUTPUT]

Output audio signals to be broadcast.

These outputs are electronically balanced, but can be converted into transformer-balanced type using optional IT-450 transformers. (See p. 57, "Converting an output into a transformer-balanced output.")

Note

Each output cannot be converted into unbalanced type as it is electronically balanced.

To convert each output into unbalanced type, use an optional IT-450 transformer.

(RM-200SF: DIP switch 6 operation or RM-200SA: DIP switch 5 operation)

The CPU OFF function permits the all-zone calls to be made from the RM-200SF or RM-200SA by bypassing the CPU*1 normally used by the SX-2000 system and using an analog link instead. This function is usually used if a system failure is preventing normal broadcasts from being made. Announcement from the RM-200SF can be made to all zones within the system only while the Talk Switch is being pressed with the CPU switch on its top panel set to OFF, or announcement from the RM-200SA can be made to the said zones while its General Urgency All-Call key is being held down for 4 seconds or more. Whether or not this function is available can be set using DIP switch 6 on the bottom panel of the RM-200SF or DIP switch 5 on the side panel of the RM-200SA. (Regarding how to make such broadcasts, see the separate Operating Instructions, "Operation.")

If the SX-2000 system receives a 24 V emergency cutoff signal ^*2 , the general urgency all-call using the CPU OFF function is disabled because the emergency system other than the SX-2000 system takes precedence over the SX-2000 system.

*1 CPU is a central processing unit, which is built in the SX-2000SM, SX-2000AI, SX-2100AI, SX-2000AO, and SX-2100AO.
*2 In the SX-2000 system, a 24 V emergency cutoff input terminal that allows control of an emergency audio input is provided on the SX-2000AO's rear panel. When the SX-2000 system is combined with another emergency system, a 24 V DC is normally kept being supplied to this 24 V emergency cutoff input terminal and is cut off in emergency situations. This interrupts the general-purpose broadcast from the SX-2000, allowing the emergency system other than the SX-2000 system to override it.

• When batteries are installed in the rack, place them directly below the VX-2000DS so that they can perform temperature compensation for the charging voltage.
  In this case, use a perforated panel in front of the rack to avoid excessive temperature rise around the batteries.

[Mounting SX-2000SM, SX-2000AI, SX-2100AI, SX-2000AO, SX-2100AO, SX-2000CI, and SX-2000CO]

• These units have no restriction to use of perforated panels and supporting runners.
- Mount these units below power amplifiers or other heat generating equipment, and at the position for easy operation and easy connection to peripheral equipment.

4. CONNECTIONS

4.1. Removable Terminal Plug Connection

Notes

• Use the screwdriver supplied with the SX-2000SM when connecting the removable terminal connector.
• Do not use a micro screwdriver. Sufficient torque is not given to the screws when tightening them, and connections may not be secured.
• Avoid soldering stranded or shielded cable, as contact resistance may increase when the cable is tightened and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.

- When connecting 2 cables or a shielded cable to a single terminal, use a ferrule terminal with an insulation sleeve to crimp the cables because such cable conductors could become loose.

* Expose 8 mm or more when using the above ferrule terminal, and cut off an extra conductor protruding from the sleeve.

Wiring procedures

Procedures below are for the removable terminal plug with fixing screws.

Step 1. Wiring the supplied removable terminal plug.

1-1. Loosen the terminal screws to insert the wire.
1-2. Tighten the terminal screws.

Ensure that the wire does not break free when pulled.

If the wire does pull free, repeat the connection procedure from the start.

Step 2. Insert the wired terminal plug into the corresponding terminal block in the unit's rear panel.

Step 3. Tighten the fixing screw.

Screwdriver (supplied with the SX-2000SM) To tighten To loosen Terminal screw Removable terminal plug Fixing screw

Notes

• Do not reverse Steps 1 and 2 above. Force is applied to the connected receptacle pins while tightening the terminal screw and they may be damaged, resulting in bad connector contact.
• When detaching the terminal plug, pull it straight out. Pulling it out at an angle may cause the terminal plug or terminal block to break.

4.2. Input Equipment Connections

4.4. Control Input/Output Connections

4.4.1. SX-2000SM

[Connecting control input terminals to the TT-104B program timer]

This connection allows timer-activated automatic broadcasts.

When the TT-104B's preprogrammed time is reached, the SX-2000SM receives a control output signal (make contact) from the TT-104B and activates preset broadcast patterns.

4.4.2. SX-2100AI

[Connecting control input terminals to the TT-104B program timer]

Since the SX-2100AI's control inputs are photo coupler inputs, they need a power supply. Power can be supplied to the photo couplers using the SX-2100AI's internal power supply or external power supply.

- When using the internal power supply, the power feed jumper and the isolation jumper are needed. Using 16P removable terminal plugs equipped with a jumper, make connections as shown below:

Notes

• Make the SX Link terminals completely independent from other LAN.
• The distance between each of SX-2000SM, SX-2000AI, SX-2100AI, SX-2000AO, or SX-2100AO and a switching hub, and between switching hubs is less than 100 m.
• Be sure to make connections of both terminals A and B.
• When using multiple switching hubs, make a star connection from the switching hub to which the SX-2000SM is connected as shown in the example 2.

4.7. Analog Link Terminal Connections

Connecting all SX-2000SM, SX-2000AI, SX-2100AI, SX-2000AO, and SX-2100AO units within the system via Analog link terminals permits general urgency all-calls to be initiated from the RM-200SA Remote Microphone or the RM-200SF Fireman's Microphone through the connected lines if normal broadcasts cannot be made due to equipment failures. (See p. 68, "CPU OFF function settings.")

The entire system can also be reset using these connected lines. (See p. 7 "15. Reset Key", p. 49 "System reset enable/disable settings.")

Make connections from the SX-2000SM's Analog link output terminal to the Analog link input terminal of the SX-2000AI, SX-2100AI, SX-2000AO, and SX-2100AO, and from the Analog link output terminal of the SX-2000AI, SX-2100AI, SX-2000AO, and SX-2100AO to the Analog link input terminal of the SX-2000AI, SX-2100AI, SX-2000AO, and SX-2100AO. Both of the SX-2000SM's Analog output terminals 1 and 2 provide the same operation.

4.8. Connections to Use the Surveillance Function

4.8.1. Speaker line surveillance (SX-2100AO only)

The speaker line surveillance function detects 3 types of failures: poor insulation (ground fault), overload (line short), and cable disconnection.

For detecting both overload and cable disconnection, use the method that detects such failures by monitoring the impedance in a speaker line (referred to as Impedance method).

Particularly to improve the accuracy of detecting cable disconnection, use the method that detects cable disconnection by connecting an End-of-line (EOL) unit at the end of speaker line (referred to as EOL method). Features of each method are shown below.

(1) Impedance method

• Applies to various types of speaker cables (no need to use shielded type cables).
• Needs no additional detector to be connected to the speaker line.
• Provides less precision in detection of speaker cable disconnection than the EOL method.

(2) EOL method

• Detects speaker cable disconnection precisely.
• Needs shielded speaker cables to be used.
• Needs an EOL unit to be connected to the speaker line.

[General description of the Impedance method]

The speaker impedance is stored in the SX-2100AO after measured with a pilot tone signal of low frequency. The SX-2100AO continuously observes the speaker line impedance, and compares it with the stored value to judge overload or disconnection of the speaker line.

The speaker line impedance may fluctuate even in normal state with the influence of impedance variations caused by the speaker's impedance change, broadcast signal frequency difference, and ambient temperature change. In such cases, the detection sensitivity can be adjusted. (See p. 130, "Speaker Line Initial Setting.")

In an application that many low power speakers are connected to an amplifier with high power output, the impedance variation stays within the measurement tolerance even if one speaker is disconnected, disabling the detection of speaker cable disconnection. In such cases, adjust the detection sensitivity of cable disconnection or select the EOL method.

[General description of the EOL method]

Shielded types of cables are used for all speaker lines, and all the shield wires are grounded.

An End-of-line (EOL) unit is connected at the furthest end of speaker line.

This EOL unit produces an impedance of specified value between the speaker line and the shield wire by using a pilot tone signal output from the SX-2100AO.

Observing this impedance, the SX-2100AO judges the speaker line to be disconnected when it cannot detect the specified value. For overload, refer to "General description of the Impedance method" described on the previous page since the SX-2100AO judges overload using the same way as the Impedance method.

Notes

• Ground all of the speaker shield wires and the SX-2100AO's chassis.

- Connect only a single EOL unit per speaker line from an amplifier output. (Do not connect 2 or more EOL units per line.)

5. SPEAKER LINE INITIAL SETTING

To perform Speaker Line Surveillance, be sure to make the initial settings for the SX-2100AO as follows after connection completion of the SX-2000 system.

5.1. Setting Items

[Initial impedance value setting]

The SX-2100AO determines whether the speaker line is open or shorted using this initial value as reference value (normal impedance value).

Important

When using the surveillance function, be sure to set the initial impedance value.

[Speaker line OPEN sensitivity adjustment]

The sensitivity can be adjusted so that the SX-2100AO can judge the speaker line open on the basis of the initial value.

[Speaker line SHORT sensitivity adjustment]

The sensitivity can be adjusted so that the SX-2100AO can judge the speaker line shorted on the basis of the initial value.

5.2. OPEN/SHORT Criterion by Comparing the Current Value with the Initial Value

The set sensitivity values and the current value are expressed as rations to the initial value (defined as 100 %). If OPEN and SHORT sensitivities remain factory-preset, the speaker line is judged shorted when the current value is less than half the initial value, and open when it is more than twice the initial value.

[Sensitivity setting example] When the SHORT sensitivity is set to 25 %, and OPEN sensitivity to 150 %.

5.3. Setting Procedures

5.3.1. Summary setting procedures

Protective cover Fluorescent display SX-2100AO Menu screen operation keys MENU ←/CANCEL - + OK / OK Key Moves the display one level down in the hierarchy. Plus Key Moves to the next item in the same hierarchy level. Minus Key Moves to the previous item in the same hierarchy level. Cancel Key Moves the display one level up in the hierarchy. Menu Key Pressing this key when default indications are displayed displays the fluorescent display's menu screen. Whenever this key is pressed, the screen returns to the default display for whatever portion of the menu screen is displayed.

Use the SX-2100AO's fluorescent display and front panel-mounted keys to perform settings. Setting the DIP switch 8 inside the protective cover on the SX-2100AO's front panel to ON enables the impedance initialization setting menu to be displayed on the fluorescent display. Follow the procedures below to perform settings for all the SX-2100AOs within the system.

5.3.4. Setting an initial impedance value

Notes

• When attenuators are connected to the speaker line, set their attenuation level to their maximum position. Otherwise, the initial impedance value cannot be set correctly.
• Be sure to perform this setting after completion of connection work.
• Be sure to reset the initial impedance value if any wiring or connection has been changed after completion of the setting.

Step 1. Press the OK key while the "SET INITIAL IMP" (Initial impedance value setting) screen is displayed. The channel selection screen is displayed.

Step 2. Select the channel to be initialized. Press the Plus (+) or Minus (−) key to select all channels or desired channel (from CH1 through CH8).

Step 3. Press the OK key. The initial value is automatically set, and the screen reverts to the screen of the channel selected in Step 2.

Note

If the initial value cannot be set, the level meter of the corresponding channel does not light. This cause possibly lies in speaker line failure (open or short) or inappropriate load. The level meter also does not light when the connection is not made.

[When the all-channel screen appears on the fluorescent display after the initial value has been set]

• The 5th indicators (segments) from the bottom of the level meters corresponding only to the speaker-connected channels light up after completion of the initial value setting. These values are the reference values.
• The level indicator goes up and down in response to the current value. The meter shows a short state of speaker line in the range above the reference value, and an open state in the range below it.

[When each individual channel is displayed on the fluorescent display after the initial value has been set]

• The 5th indicator (segment) from the bottom of the selected channel's level meter lights up after completion of the initial value setting. This value is the reference value.
• The level indicator goes up and down in response to the current value. The meter shows a short state of speaker line in the range above the reference value, and an open state in the range below it.
• Current impedance status of the selected channel can be checked in the text display area.

Current value: Displays the ratio of current impedance to the initial one in real-time.

This indicator remains unlit when the speaker line is not connected. The display range is 0 to 9999 and over. A blank is displayed if no initial setting is or could have been performed.

Judgment: Displays the judgment results below.

The 5th indicator (segment) from the bottom

Note: The figure shows an example when CH3 is selected.

5.3.5. Adjusting the speaker line's OPEN sensitivity

Open sensitivity is expressed as the ratio to the initial value (defined as 100 %) and can be adjusted in the range of 101 % to 800 %. It is set to "200" (the 4th indicators from the top light) for all the channels by default.

Note

Moving the setting closer to 101 % increases the OPEN sensitivity, and thus improves the accuracy of "OPEN" detection. Moving the setting closer to 800 % decreases the OPEN sensitivity, and thereby stabilizes the operation of the "OPEN" detection.

Step 1. Press the OK key while the "ADJUST OPEN RANGE" (Speaker line OPEN sensitivity adjustment) screen is displayed.

The "SELECT CHANNEL" (channel selection) screen is displayed.

OPEN sensitivity set positions for the all channels can be confirmed from the light-up positions of the LEDs. (Lighting range of the LEDs corresponds to the variable range of 101 to 800 of the OPEN sensitivity.)

(Level meter on the fluorescent display)

Light-up position at 200 by default (as a rough guide)

Step 2. Select the channel for which the setting is to be changed.

Press the Plus (+) or Minus (−) key to select all channels or desired channel (from CH1 through CH8).

Selected channel(s) can be confirmed by the Channel selection indicator(s) on the fluorescent display.

(Channel Selection Indicators on the fluorescent display)

Indicator corresponding to the selected channel lights red.

Step 3. Press the OK key.

The OPEN sensitivity setting screen for the selected channel is displayed.

The set value of the selected channel is displayed in the text display area.

Step 4. Set the value using the Plus (+) or Minus (−) key.

The setting range is 101 to 800.

Values can be adjusted in 1 steps ranging from 101 to 110, in 10 steps ranging from 110 to 200 and in 100 steps thereafter. The light-up position of the LED goes up or down accordingly when the setting value is changed.

Step 5. Press the OK key.

The setting save starts with its process message displayed, and the screen reverts to that in Step 4 when finished.

Be sure to save the settings as doing otherwise may cause them to revert to the original settings at the time of system reset.

5.3.6. Adjusting the speaker line's SHORT sensitivity

SHORT sensitivity is expressed as the ratio to the initial value (defined as 100 %) and can be adjusted in the range of 5 % to 50 %. It is set to "50" (the indicators at the top light) for all the channels by default.

Note

Moving the setting closer to 5% decreases the SHORT sensitivity, and thereby stabilizes the operation of the "SHORT" detection.

Important

Adjust the SHORT sensitivity within the range not exceeding two times the power amplifier's rated load, as doing otherwise may cause damage to the power amplifier.

(Example)

• When the speakers with the rated load are connected: Set to "50."
• When the speakers with 1/2 rated load are connected: Set in the range of "25" to "50."

Step 1. Press the OK key while the "ADJUST SHORT RANGE" (Speaker line SHORT sensitivity adjustment) screen is displayed.

The "SELECT CHANNEL" (channel selection) screen is displayed.

SHORT sensitivity set positions for the all channels can be confirmed from the light-up positions of the LEDs. (Lighting range of the LEDs corresponds to the variable range of 5 to 50 of the SHORT sensitivity.)

(Level meter on the fluorescent display)

The indicators at the top light when set to "50" by default.

Step 2. Select the channel for which the setting is to be changed.

Press the Plus (+) or Minus (−) key to select all channels or desired channel (from CH1 through CH8).

Selected channel(s) can be confirmed by the Channel selection indicator(s) on the fluorescent display.

(Channel Selection Indicators on the fluorescent display)

Indicators corresponding to the selected channel light red.

Step 3. Press the OK key.

The SHORT sensitivity setting screen for the selected channel is displayed. The set value of the selected channel is displayed in the text display area.

Step 5. Press the OK key.

The setting save starts with its process message displayed, and the screen reverts to that in Step 4 when finished.

Be sure to save the settings as doing otherwise may cause them to revert to the original settings at the time of system reset.

5.3.7. Clearing the settings

The initial impedance value and the set values of OPEN and SHORT sensitivity can be cleared and reset to the factory default.

Step 1. Press the OK key while the "CLEAR INITIAL IMP." (Setting clear) screen is displayed.

The "SELECT CHANNEL" (channel selection) screen is displayed.

Step 2. Select the channel for which the setting is to be cleared.

Press the Plus (+) or Minus (−) key to select all channels or desired channel (from CH1 through CH8).

Selected channel(s) can be confirmed by the Channel selection indicator(s) on the fluorescent display.

7. TIME SETTINGS

Time, which is recorded in the SX-2000 system's operation log inside the SX-2000SM, must be set.

Note

The SX-2000SM's internal battery will retain the set time for approximately one week. If there is a period of a week or longer between equipment assembly and wiring to on-site installation, it will likely be necessary to perform the time setting again after the system is installed on the site.

Step 1. Connect the SX-2000SM and the PC installed with the SX-2000 software to the switching hub.

Connect the SX-2000SM's LAN connection terminal to a 10BASE-T- or 100BASE-TX-compatible switching hub.

Use STP Category 5 Standard straight LAN cable fitted with RJ45 connectors.

Notes

• The distance between the SX-2000SM and the switching hub must be less than 100 meters.
• Do not connect the switching hub to the LAN.
• Avoid directly connecting the SX-2000SM to the PC via a cross cable.

8. KEY LOCK SETTINGS AND CANCELLATION

8.1. SX-2000AI and SX-2100AI (DIP Switch 1 Operation)

It is possible to disable the input volume controls and channel keys in order to prevent mistaken operation. The input volume level set while the key lock function is used takes effect after the key lock has been released.

Note

When the SX-2000 system is placed in an emergency condition during key lock OFF, the emergency sound level preset with the front-mounted volume control knob is invalid, but that defined by the SX-2000 Setting Software is valid.

During key lock ON, however, the volume level set with the input volume control knob is valid even if the SX-2000 system is placed in an emergency condition. Before setting key lock function to ON, be sure to adjust the input volume control knob corresponding to the emergency source channel for a proper sound level.

8.2. SX-2000AO and SX-2100AO (DIP Switch 1 Operation)

It is possible to disable the output volume controls and channel keys in order to prevent mistaken operation. The output volume level set while the key lock function is used takes effect after the key lock has been released.

Note

When the SX-2000 system is placed in an emergency condition during key lock OFF, the output level for the emergency broadcast zone preset with the front-mounted volume control knob is invalid, but that defined by the SX-2000 Setting Software is valid.

During key lock ON, however, the volume level set with the output volume control knob is valid even if the SX-2000 system is placed in an emergency condition. Before setting key lock function to ON, be sure to adjust the output volume control knob corresponding to the emergency broadcast zone for a proper sound level.

9. OUTPUTTING LOG DATA (SX-2000SM: DIP Switches 1 and 2 operations)

By writing the SX-2000 system's log data to a CF card in the ".s2l" file format and displaying this data on a PC installed with the SX-2000 Setting Software, the data can be output as an Excel CSV file. The log data includes 2 types of data: Operation log data that contains all logs and Failure log data that contains only failure logs. Both data are saved to a CF card with a file name "Sx2kOp**.s2l" for the Operation log data and "Sx2kFa**.s2l" for the Failure log data automatically assigned. ("**" represents a number from 00 to 99 indicating the order in which the logs have been saved. If more than 100 files are saved, the oldest files are overwritten in chronological order.)

The newness or oldness of a file may be ascertained by checking its date. Shown below is the procedure for writing the SX-2000SM's log data to the CF card.

Notes

• When storing log data on a CF card, confirm in advance that it has at least 15 megabytes of free space.
• Do not operate the DIP switch while the CF card access indicator inside the protective cover is flashing.
• Reactivating the SX-2000SM erases the log data temporarily stored in SX-2000SM memory.
  So, when storing log data on a CF card, be sure to perform that before reactivating the SX-2000SM.
• The SX-2000SM operates on the current setting data until restarted even if the CF card has been removed from the SX-2000SM for reading log data.
  • Operation log data is recorded every hour.
• Failure log data is recorded within 100 seconds after a failure has occurred.

Step 1. Remove the protective cover on the SX-2000SM's front panel by removing the screws securing it using a Phillips screwdriver.

graph LR
    A["Protective cover"] --> B["Inside of the protective cover"]

    B --> H["CF CARD"]
    B --> I["ON"]
    B --> J["1 2 3 4 5 6 7 8"]
    B --> K["Screw"]

Step 2. Set DIP switch 1 to ON. Log data is saved to the CF card at this time.

ON 1 2 3 4 5 6 7 8

Note: DIP switch 1 is set to OFF by default.

Step 3. Confirm that the CF card access indicator has gone off, then set DIP switch 1 to the OFF position.

ON 1 2 3 4 5 6 7 8

Step 4. Set DIP switch 2 to ON. Access to the CF card stops, allowing the card to be removed.

ON 1 2 3 4 5 6 7 8

Step 5. Remove the CF card from the card slot.

Step 6. Insert the CF card into the PC's card slot and start the SX-2000 Setting Software.

Confirm the log data using the SX-2000 Setting Software.

For details, see the separate Setting Software Instructions, "Utility."

Step 7. Insert the CF card with the saved settings data into the SX-2000SM's CF card slot.

Inserting the CF card causes the buzzer to sound.

Setting DIP switch 2 to OFF in Step 8 stops the buzzer.

Step 8. Set DIP switch 2 to OFF.

The CF card can be inserted.

Note

When changing the setting data, be sure to press the Reset key to restart the SX-2000 system after turning off DIP switch 2.

Reactivating the system stops broadcasts currently in progress.

APPENDIX: ADDITIONAL INSTALLATION INSTRUCTIONS FOR AN EN 54-16 COMPLIANT SYSTEM

1. GENERAL INFORMATION

1.1. Terms and Abbreviations

The following terms and abbreviations are used in the further text:

access level: the access to parts as indications or controls must either be directly available or be restricted. This is defined by the different access levels.

CIE: control and indication equipment, this is usually the fire detection system

mandatory indication: these indications must ____ be provided to comply with EN 54-16.

option with requirements: this option is an option in the EN 54-16 that must fulfil certain requirements. It is not mandatory to use these options.

VA: voice alarm (emergency)

VACIE: voice alarm control and indication equipment, this means the SX-2000 system

1.2. Access Levels

Four access levels are clearly defined in the standard EN 54-16. The access levels 1 and 2 are for the user access to the VACIE, and the access levels 3 and 4 are for the installer and the manufacturer only.

The installer must prepare the access to certain functions in access level 1 or 2 when installing and configuring the SX-2000 system. The details are described in the next chapters.

1.2.1. Access level 1

(Citation of EN 54-16:)

Parts in access level 1 must be visible and/or accessible by member(s) of the general public or persons having a general responsibility for safety supervision who might be expected to investigate and initially respond to a fire alarm or a fault warning.

All mandatory indications shall be visible at access level 1 without prior manual intervention (e.g. the need to open a door). Manual controls at access level 1 shall be accessible without special procedures.

Indications and manual controls that are mandatory at access level 1 shall also be accessible at access level 2.

(Explanation:)

Usually the cabinet racks containing the SX-2000 system are installed in a separate (engine) room. The access level 1 requirements are fulfilled when persons having a general responsibility for safety supervision (...) have access to this room.

1.2.2. Access level 2

(Citation of EN 54-16:)

The entry to access level 2 shall be restricted by a special procedure. The procedure may require

- mechanical keys,

- a code of at least 3 manual sequential operations, or

- access cards.

Parts in access level 2 must be visible and accessible by persons having a specific responsibility for safety and who are trained and authorized to operate the VACIE in the:

- quiescent condition,

- voice alarm condition and

- fault warning condition.

(Explanation:)

A lockable room is access level 2 when only persons having a specific responsibility for safety and who are trained and authorized to operate the VACIE can unlock it. An emergency microphone can be installed inside a lockable (wall-mount) box to fulfil this requirement.

1.2.3. Access level 3

(Citation of EN 54-16:)

The entry to access level 3 shall be restricted by a special procedure, differing from that for access level 2. The procedure may require

• mechanical keys,
• tools, or
• an external programming device.

Parts in access level 3 must be accessible by persons who are trained and authorized:

• to re-configure the site specific data held within the VACIE or controlled by it (e.g. labelling, zoning, alarm organization),
• to storage and change of emergency tones and messages and
• to maintain the VACIE in accordance with the manufacturer's published instructions and data.

(Explanation:)

When the cabinet racks are in access level 1, then the covers on the SX-2000SM, SX-2100AI, SX-2000AO, SX-2100AO, SX-2000CI and SX-2000CO must be closed after accessing by an authorized person.

1.2.4. Access level 4

(Citation of EN 54-16:)

The entry to access level 4 shall be restricted by special means which are not part of the VACIE.

Parts in access level 4 must be accessible by persons who are trained and authorized by the manufacturer to either repair the VACIE or alter its firmware, thereby changing its basic mode of operation.)

1.3. Declaration for the VACIE SX-2000 according to EN54-16 §13.1.2

The design for the VACIE SX-2000 has been carried out in accordance with a quality management system which incorporates a set of rules for the design of all elements of the VACIE, and that the components of the VACIE SX-2000 have been selected for the intended purpose and are expected to operate within their specifications when the environmental conditions outside the cabinet of the VACIE comply with EN54-16 § 13.1.2.

2. INDICATIONS AND CONTROLS IN ACCESS LEVEL 1

2.1. Mandatory Indications and Controls in Access Level 1

All mandatory indications and controls must be provided and installed in access level 1. The minimum requirement is to provide them all on one cabinet rack or when a system is divided in several cabinet racks, then they can be distributed over several ones if these are installed adjacent to each other.

Two of the mandatory indications are available on the system manager SX-2000SM, the other mandatory indications must be realised on a remote microphone which must be installed adjacent to the cabinet rack (on front or side of the rack or on the wall next to the rack). If this remote microphone is programmed to be an emergency microphone, then it must not contain any function that has to be in access level 2 (refer to chapter 3).

The mandatory indications are listed below. Each stated indication requires its separate indicator (LED).

No.	Indication	Control	Preparation
1	VA condition	-	implemented in SX-2000SM, RM-200SA and RM-200SF
2	General fault	fault receipt button	- available on the SX-2000SM (no preparation required);- can be programmed on a remote microphone:prepare a fault pattern including all faults of each alarm-related system elements and speaker lines (including also the faults which require a separate indication) assign this fault pattern to one fault receipt button.
3	CPU fault	fault receipt button	The system fault (CPU hang-up) is displayed on the SX-2000SM.
4	Power supply fault	fault receipt button	This fault can be programmed on a remote microphone by assigning all faults related with the VX-2000DS (basically by all units where the VX-2000DS' are connected to) to one fault receipt button.Prepare a fault pattern containing all SX units where the VX-2000DS is connected to.Assign this pattern to one fault receipt button.
5	Fuse rupture	fault receipt button	This fault can be programmed on a remote microphone by assigning all amplifier faults and SX-2000 unit's (SX-2000SM, SX-2100AI, SX-2000AO, SX-2100AO, SX-2000CI and SX-2000CO) faults to one fault receipt button.Prepare a fault pattern containing all above mentioned SX units and all amplifiers.Assign this pattern to one fault receipt button.
6	Fault in a signal path between decentralised system racks	fault receipt button	Program a fault warning for every port of the Ethernet switches of the IES-3000 series used for SX-2000 unit connections.Connect their fault outputs to control inputs of the SX-2000 system.Program these control inputs for an external fault. Make a fault pattern for these faults including the activation of a common control output.Connect this control output with a control input and set this to be an external fault input.Make a fault pattern for this fault input and assign it to a fault receipt button of a remote microphone.

(continuation of the table of previous page)

No.	Indication	Control	Preparation
7	-	Lamp test	A lamp test must be provided for all mandatory indications. A lamp test button is available on the system manager SX-2000SM for its indications and the lamp test button must be programmed on the remote microphone(s) used for the mandatory indications.A lamp test must also be programmed on a button of remote microphones that provide emergency control.
8	Earth leakage	-	All earth leakage faults are implemented in other fault detections, therefore this separate indication is not required.

Table 1: Mandatory Indications and Controls in Access Level 1
If wanted, the mandatory indications and controls can additionally be assigned to other remote microphones or other indication and control devices.

2.2. Options Requiring Indications and Controls in Access Level 1

The following options can be used if required. They belong to the so called options with requirements. That means, if they will be used, then they must fulfil the requirements.
The two applicable options with requirements that require mandatory indications are certain fault indications. The covered faults must be indicated acoustically and visible by a yellow indication (lamp/LED) in access level 1, so a fault receipt button must be provided and a lamp test must be available for all these failure indications. It is the best to program these functions on the remote microphone that is installed adjacent to the cabinet rack (refer to the previous chapter 2.1).

No.	Indication	Requirement and Preparation
9	faults in VA zones (EN 54-16, §8.4)	Requirement: a fault in each VA zone must be indicated separately, i.e. by a separate LED per VA zone.Assign surveillance to each speaker line of the whole emergency area.For each VA zone, combine the speaker line faults of the same VA zone to a failure output pattern, i.e. each VA zone must have its own pattern.Assign each of these failure pattern to a separate fault receipt button of a remote microphone which must be installed adjacent to the main rack in access level 1.

Table 2: Options requiring Indications and Controls in Access Level 1

2.3. Examples for the Mandatory Indications and Controls

2.3.1. Minimum configuration

The minimum requirements are listed in chapter 2.1 from no. 1 to 7. The installation shall be made in a room of access level 1 and no front door of the cabinet rack shall prevent a quick access to the indication and control units. The remote microphone shall be installed adjacent to the cabinet rack containing the system manager SX-2000SM. When several cabinet racks are installed adjacent to each other and one of them containing the system manager, then the remote microphone can be installed adjacent to another cabinet rack in that group. The best place would be next to the system manager to see all indications together.

The remote microphone must not contain any emergency related function or a fault reset button (refer to chapter 3.1 and 3.2). When paging shall be provided, then the remote microphone must be of general type, i.e. the RM-200SA in general mode because paging must not be available when the system is in emergency mode. In this case no emergency related function can be set as required by access level 1. We recommend to use the RM-200SA in general mode to avoid setting of emergency controls.

Minimum configuration:

(4) fault acknowledge for (2) - (3) and (7) - (9)
(5) lamp test button
(6) when the RM-200SA is set to be a general microphone, then this button cannot be programmed. Its related LED indicates the VA condition (emergency mode).
(7) power supply fault (fault receipt programming)
(8) fuse rupture (fault receipt programming)
(9) only when the system is installed in more than one location: fault in a signal path between decentralised system racks (fault receipt programming); otherwise the lamp test can be assigned to this button
(10) lamp test (if not set on (9))
(11) no function (may be used for non-emergency related functions as paging etc.)

2.3.2. Configuration with indication of faults in VA zones

In this example, the minimum requirements listed in chapter 2.1 from no. 1 to 7 are expanded by the fault indications of VA zones. The installation shall be made in a room of access level 1 and no front door of the cabinet rack shall prevent a quick access to the indication and control units. The remote microphone shall be installed adjacent to the cabinet rack containing the system manager SX-2000SM. When several cabinet racks are installed adjacent to each other and one of them containing the system manager, then the remote microphone can be installed adjacent to another cabinet rack in that group. The best place would be next to the system manager.

The remote microphone must not contain any emergency related function or a fault reset button (refer to chapter 3.1 and 3.2). When paging shall be provided, then the remote microphone must be of general type, i.e. the RM-200SA in general mode. We recommend to use the RM-200SA in general mode to avoid setting of emergency controls.

When applying the fault indication of VA zones (option with requirement, refer to item 9 of chapter 2.2), then - add surveillance on all VA related outputs

• assign each output of the same VA zone to one failure pattern, i.e. one failure pattern per VA zone
• assign each failure pattern to its own fault receipt button of the indicating remote microphone

If the number of VA zones is more than 9, then further fault indications (fault receipt buttons) can be assigned on buttons of the keyboard extension RM-210 connected to the remote microphone.

3. INDICATIONS AND CONTROLS IN ACCESS LEVEL 2

Basically all alarm related manual controls and the fault reset control must be in access level 2.

3.1. Mandatory Control in Access Level 2

All faults except two ones in the SX-2000 system are reset automatically when the fault is not available anymore. The faults of amplifiers and short circuits on the speaker line require a fault reset control to re-enable the operation of them (before the reason of the fault should be removed). Therefore the fault reset button must be available but has to be in access level 2.

No.	Indication	Preparation and requirements
10	manual fault reset	- fault reset button on system manager SX-2000SM (preparation in chapter 8, for the operation refer to the text below this table);- programming the fault reset function on a remote microphone requires to install the remote microphone in access level 2 (refer to the chapter 3.3.1 installation place);- programming the fault reset function on a control input requires to install the connected switch to be in access level 2 (e.g. in a lockable box)

Table 3: Mandatory control in access level 2

Since the system manager SX-2000SM shall be installed in access level 1 but also containing a fault reset button, its operation was modified to meet the access level 2 requirements (refer to chapter 8 also). It is necessary to proceed a 3-step sequential procedure to make a fault reset on this button:

1. push the fault reset button start for a duration between 0.1 - 1.5 seconds and release it
2. push the fault reset button within 2 seconds after the previous push start for a duration between 0.1 - 1.5 seconds and release it
3. push the fault reset button within 2 seconds after the previous push start for a minimum duration of 2 seconds and release it

When the pushing procedure does not cause the fault reset, then the done action was probably wrong. Then wait for 2 seconds after the last button release and start the sequence again.

3.2. Options requiring Controls in Access Level 2

All the listed functions in the next table belong to the option with requirements "VA manual control" ( §10 ).

No.	Indication/control	Requirement and Preparation
11	Manual reset of the VA condition	Requirement: this function must be in access level 2. The manual VA reset can be assigned to a button of an emergency microphone. Please refer to the software manual for further details. If the emergency reset shall be made by an external switch, then assign this function to a control input. The connection to the switch should be monitored and the switch shall be put into access level 2.
12	Indication of the status of VA zones / zone groups	The zone status is indicated by buttons assigned for zone selection on a remote microphone. So assign the same VA zones or VA zone groups to zone selection buttons as are available for the manual controls.

Table 4: Options requiring controls in access level 2

The options

- manual emergency activation,

- manual emergency phase shift,

- manual silencing of the voice alarm condition,

- faults of manually controlled VA zones (EN 54-16, §10.3)

must not be used because these are not certified yet. A certification is planned later.

3.3. Proposal for the Installation and Setting of an Emergency Microphone

3.3.1. Installation place

The emergency microphone (RM-200SA in emergency mode, RM-200SF) must be installed in access level 2. To do so, either install the emergency microphone in a lockable (wall-mount) box or in a room with access only by mechanical keys, access cards or entering a code of at least 3 manual sequential operations. The room or the box must be accessible only for persons having a specific responsibility for safety and who are trained and authorized to operate the emergency microphone in the voice alarm condition.

3.3.2. Settings

Depending on the requirements for the use of the emergency microphone, one or more VA zones or VA zone groups shall be set. A possibility of starting the emergency shall be provided (by emergency pattern). Fault indications (fault receipt buttons) can be set when the emergency microphone is used for paging only. Faults receipt buttons for VA zones or VA zone groups must be set if a manual control of the emergency is provided. When these fault receipt buttons are set, then these shall cover the same VA zones or VA zone groups as used for the zone selection buttons. A general fault indication might be provided also.

Table 5: Overview of the Access Level Requirements for the Equipment and related Functions

5. POWER SUPPLY

The SX-2000 system must use the power supply system VX-2000DS ER/UK with VX-200PS ER/UK and VX-2000PF certified on EN 54-4.

The power indications must be visible in access level 1, i.e. the cabinet racks containing the VX-2000DS ER/UK must be installed in access level 1.

6. CABINETS

The cabinet racks of the CR-series, namely the CR-15, CR-22, CR-27, CR-35, CR-40 and CR-44, shall be used for installing the system components.

Each cabinet rack containing this certified SX-2000 equipment must be labelled with the label shown below. This label will be supplied as accessory with each SX-2000SM and SX-2100AO.

The same label will be provided for the remote microphones. When you install them inside a (lockable) box, put the label onto this box.

The label must be affixed so that it can be seen in access level 1.
