USER MANUAL BLK-4 VIKING

Provide LED Strobe / Beacon Visual Indication of Line Status

The BLK-4 provides high visibility indication of analog line status through a high powered 360° LED strobe and/or beacon visual indicator. The BLK-4 is the ideal solution for the hearing impaired and can be used equally well in loud warehouses or factories, where ringing phones can not be heard. Alternatively, the BLK-4 can be used to add emergency notification to pre-existing emergency phones by turning on the strobe light when the emergency phone is in use.

The included control module has a disable input which is ideal for two-button emergency phones, such as Viking's E-1600-20A, allowing "Info" button calls to be placed without activating the relay (turning on the emergency strobe light, camera, etc.) Four DIP switches are provided for turning ring detection on or off, off-hook/loop detection on or off, 12VDC or dry relay contact output and for selecting a ring cadence mode which allows the relay to follow ringing or to remain activated during the off time of standard ring cadence. The control module can be installed on any standard telephone line or analog PABX/KSU station. The strobe can be interfaced to flash on ringing, off-hook or a combination of ringing and off-hook (line in-use).

The BLK-4 is designed for indoor applications. The BLK-

B. Configuring for Ring and/or Loop/Off-Hook Indication

* Note: The gel-filled (water tight) butt connectors are designed for insulation displacement. Do not strip wires prior to terminating.

1. Ring Indication Only

Connect the incoming line to the red and green wires with the yellow stripe as shown in the diagram. No phone/terminal device is required. The control module can monitor for ringing any place along the ringing line.

2. Loop/Off-hook Indication Only

The control module must be placed between the phone line and the phone/terminal device to be monitored. Connect the incoming line to the red and green wires with the yellow stripe and connect the phone/terminal device to the brown and gray wires as shown.

3. Both Ring and Loop/Off-hook Indication

If the application requires ring and loop/off-hook indication, the control module must be placed between the phone line and the phone/terminal device to be monitored. Connect the incoming line to the red and green wires with the yellow stripe, connect the phone/terminal device to the brown and gray wires.

C. Ring Cadence Mode

DIP switch 2 is used for switching between different ring detection modes. In the OFF position, the relay and switched 12VDC output will activate only while ring voltage is present and will turn off between rings. In the ON position, the relay and switched 12VDC output will remain on for up to 5.75 seconds after the ringing has stopped. This allows the relay and 12VDC (flashing strobe light) to remain on between rings of a standard ring cadence. Note: To use the Ring Cadence Mode, ring detection MUST be enabled (DIP switch 1 - ON).

D. Auxiliary Relay Contacts

With DIP switch 4 OFF, normally open and normally closed dry relay contacts are available on the orange, purple and yellow wires. The contacts are rated at .5A @ 125VAC/1A @ 30VDC. If contacts are driving an inductive load, place a suppression device at the load to snub high voltage spikes.

With DIP switch 4 ON, wet/switched +12VDC (100mA maximum) will be output on the yellow wire and “-” (GND) on the black wire.

E. Switched 12V DC Output

The switched 12V DC output is a low current, 12-15VDC output that is turned on only while the trigger input is closed or ring/loop detect relay is activated. This switched power output is ideal for triggering the included strobe light or providing 12-15V DC power to any device that draws less than 400mAmps. The positive side is available on the green wire, and the negative side is on the black wire. Once all the line and load connections have been made, plug in the 115 V AC wall adapter, and replace the cover.

F. Disable Feature

By connecting the Disable/Info Switch input of the BLK-4 control module to the "Info" switch of Viking's E-1600-20A, E-1600-20A-EWP, E-1600-52A or E-1600-52A-EWP Emergency Phone, any outbound call initiated from the "Info" button will not activate the strobe light. This way, only the "Help/Emergency" outbound calls will activate the relay. Cut one of the "Info" switch wires in half and connect each end to the blue wires on the BLK-4 control module as shown in the diagram at the right. Note: This Disable input is NOT polarity sensitive. The "Disable" input can be connected to a switch for remotely disabling/turning off the device (strobe light, camera, etc.) controlled by the BLK-4 control module. For more information, see DOD# 866.

G. Trigger Input

The trigger input is available on the two white wires. The Strobe Light, Auxiliary relay contact and the switched 12 VDC output will be activated for the duration of the contact closure across the two white wires.

The SL-2 can be user programmed as a Beacon only, Strobe only or Beacon/Strobe. The brightness setting can be programmed separately for the Strobe or Beacon and one of 4 different Flash Patterns can be programmed for the Strobe (see Strobe Flash Patterns, section D).

IMPORTANT: The SL-2 is factory default programmed as a steady on beacon with a single flash strobe when activated. The beacon and strobe are set to their brightest settings. All programming should be done prior to connecting to the BLK-4 control module.

A. Accessing the Programming Mode

(Optional, the SL-2 is factory programmed to the Beacon/Strobe Mode and brightest Beacon/Strobe settings).

Step 1.	Apply 10-15 VDC power to the Red (+) and Black (-) wires.
Step 2.	Touch and hold the Green (Control) wire to the Black (-) wire for 3 seconds. The strobe should flash twice. You are now in Programming mode. Note: Once in the programming mode, if a programming command has not been entered for 20 seconds the strobe will flash 3 times indicating the unit has exited programming and returned to the Run Mode.

B. Programming Desired Features (after accessing Programming Mode above)

Select the Feature: Momentarily touch the Green (Control) wire to the Black (-) wire 1 to 10 times to select which feature to program (see Programming Features List, section C). The strobe should momentarily flash each time the Green (Control) wire has touched the Black (-) wire.

Features 1-3 & 6-10: After selecting Programming Features 1-3 or 6-10, wait 3 seconds and the strobe should flash 2 times indicating that feature has been programmed. You can now exit programming or move on to programming the Beacon or Strobe brightness settings.

Setting Strobe Brightness (factory set to 6/Brightest): After selecting Programming Feature 4 (Strobe Brightness), wait 3 seconds and the strobe should begin flashing in the preprogrammed flash pattern. Touch and hold the Green (Control) wire to the Black (-) wire. The SL-2 will begin flashing the strobe cycling through 6 different brightness settings from lowest to highest. When the SL-2 flashes at the desired brightness level immediately remove the Green wire from the Black. The SL-2 should flash twice indicating the selected brightness level has been set.

Setting Beacon Brightness (Factory set to 6/Brightest): After selecting Programming Feature 5 (Beacon Brightness), wait 3 seconds and the beacon will light at its preprogrammed beacon brightness setting. Touch and hold the Green (Control) wire to the Black (-) wire. The SL-2 will begin stepping through 6 different beacon brightness settings from lowest to highest. When the SL-2 lights at the desired beacon brightness level immediately remove the Green wire from the Black. The SL-2 should flash twice indicating the selected brightness level has been set.

Exiting Programming: To exit programming simply wait 20 seconds from the last programming command and the unit will flash 3 times. This indicates the SL-2 has exited the programming mode and is now in the Run mode. Note: To eliminate waiting 20 seconds, you can also exit programming after the last programming command by touching and holding the Green (Control) wire to the Black (-) for 3 seconds. The strobe will flash 3 times indicating the unit has exited the programming mode and is now in the Run mode.

Operation

A. Ring Indication (DIP Switch 1 ON)

When the control module detects an incoming ring signal, it activates a set of normally open or normally closed contacts and turns on the 12VDC output for activating the provided strobe light. With the Ring Cadence mode off (DIP switch 2 OFF), the relay will activate and the strobe light will flash only during ringing. With the Ring Cadence mode ON (DIP switch 2 ON), the relay will remain activated and the strobe light will remain flashing between rings.

B. Off-Hook Indication (DIP Switch 3 ON)

When the control module detects an off-hook condition (loop current) on the brown and gray wires, it activates a set of normally open or normally closed contacts and turns on the 12VDC output for activating the provided strobe light. The relay contacts will remain activated and the blue strobe light will flash during the off-hook condition and will stop flashing approximately 3 seconds after the phone/terminal device on the brown and gray wires is back on-hook.
