Speaker circuits shall be supervised for short and open circuit conditions, and shall be able to withstand transient or continuous short-circuit conditions without damage to the system.
System may be configured for General Alarm All Call operation, Alarm by Zone or Floor Above / Floor Below as required. Contact closures shall allow immediate broadcast of an alarm signal and evacuation message to the appropriate area. Non-Alarm areas may receive alert tones and messages as required or activated by the FACP.
The alarm signal/evacuation message shall be broadcast until the FACP is reset, or until emergency personnel interrupt the broadcast with a manual page.
To prevent unauthorized tampering, the voice evacuation system shall disable the microphone if the microphone is keyed continuously for 3 minutes or more. Systems that do not have this feature shall not be acceptable.
Please read this Manual completely before installing the HMB System.
INSTALLATION
Installer must insure that all wiring and devices installed in system meet the following standards:
National Electrical Code (NFPA 70)
NFPA Standard 72
Life Safety Code (NFPA 101)
Install equipment in a clean, dry environment, avoid installation where equipment could be subjected to vibration. ** Make sure all Non-Power Limited cabling is separated from Power Limited cabling.**
WIRING (Refer to wiring and terminal designation diagrams)
MASTER PANEL
- Connect Netcom Bus between all panels. Maximum distance between panels is 4000' (min 16 AWG) or 120 Ohms max. Impedance. See page 5 for wire type.
- Connect AC power to master panel and then connect batteries.
- Once power is on to the unit, connect battery wiring harness from the PWR power supply board TB-1 Red (+) / Black (-). Observe polarity. Minimum battery size is 7AHr. (Max 24 Ahr in a separate Battery cabinet) (use 2 12V batteries connected in series) *See Master panel wiring diagram on page 6. *
NOTE: Wiring for batteries and 120 VAC is Non Power-Limited. Care must be taken to insure that all Power-Limited wiring maintain a minimum spacing of 14 from any Non Power-Limited wiring. If batteries must be located in separate enclosure, provide separate conduit run for battery wiring only.
DISTRIBUTED PANELS
(Maximum number of Distributed Panels is 250 on a system)
- Speaker circuits require an End of Line resistor for supervision. Attach a "reference value" EOLR for the speaker circuits to TB9 - 1 & 2 on MBR board. This value must be placed at the end of the speaker line as well. The system is shipped from the factory with 10kOhm12 watt EOLR.
- Connect all speaker loops (UL listed devices) to TB1 - TB4 along the top edge of the MBR mother board in the Distributed panels. Fire Phone circuit connects to TB5.-TB6 on the left side of the MBR Motherboard in the Distributed panels.
-
Connect 120 VAC, 60 Hz, power to the black and white pigtail leads from transformer primary. Secure ground lead to grounding stud in cabinet located on the backplate.
-
Once all power and circuits are connected, initiate a 'Global Reset' This is done by holding the "Fault Silence" switch in the up position while the 'System Reset' switch is clicked twice. This will rerun the 'Power On Diagnostics' program. The Green LED will remain on to indicate that the HMB system is fully operational and all circuits are nominal. Observe the display during the reset, it will show how many DP in the loop.
BATTERY MAINTENANCE
Typical battery life is approximately 3-5 years depending on usage. Always replace both batteries with same amp hour ratings and of approximately the same age. Refer to the battery manufacturer's specifications for the particular battery used.
System Operation
\*\*Note\*\* ALL panels in system are pre-programmed at the factory
Alarm When an input on the MX-II FACP Interface card is pulled down to circuit common (0VDC), the Evacuation Signal and Message will be broadcast into the selected Evacuation Zone. If 'Floor-Above/Floor-Below' has been enabled, the Evacuation Zone for the floor above and the floor below the selected zone(s) will also be activated.
The floor(s) receiving the Alarm Tone/Message is displayed by a slow (2 second) flashing of the LED associated with the Evacuation Zone on the Paging Control panel.
If 'Set Alert Non Fire Floors' has been enabled in programming, all floors not broadcasting the Evacuation Signal and Message will begin broadcasting the Alert Signal and Message.
In addition, if the paging microphone is used and no Evacuation/Paging Zones have been manually selected, paging will automatically be routed to those zones that are in alarm. The Evacuation Signal will resume when paging is ended as will the Evacuation Message.
If an Evacuation/Paging Zone is selected manually, paging will take place in the selected zone, or zones, only (operation if system was designed as "dual" channel)..
Within a single Distributed Panel, and due to the nature of Dual Channel systems using one amplifier per channel, paging into an Evacuation/Paging Zone broadcasting the Alert Signal and Message will silence the other zones also broadcasting the Alert Signal and Message if there is also a zone broadcasting the Alarm Signal and Message. In other words, within a single Distributed panel only two audible signals can be broadcast at one time, either Alarm and Alert Signals, Alarm Signal and Paging or Alert Signal and Paging.
Paging When an Evacuation/Paging Zone is selected by the operator using the associated switches on the Paging Control panel, the LED(s) will indicate which zone(s) have been selected. The All-Call switch on the HMB Control panel will select all zones for paging when clicked once. A second click of the All-Call switch will deselect all zones.
The Zone Selection switches indicate which zones have been selected for paging. Broadcast of live voice messages does not take place until the Push-to-Talk switch on the microphone is pressed.
Fire Phone When a Fire Phone Handset is plugged into a Fire Phone Jack, the LED on the Zone Control panel associated with that Fire Phone zone will start flashing. A ringing signal will be heard to indicate that a handset has been jacked in. The ringing signal will cease when the Fire Phone Zone is selected.
Normally, only one Fire Phone Zone is selected at a time. Selecting another zone where a handset is jacked in will deselect the other zone(s).
HMB Control Panel Refer to Master Panel Controls and Display diagram (Page 6).
The Control Panel status indicators are 'Alarm', 'Fault' and 'Power'.
During 'Power On Diagnostics', the system is scanned for active Distributed Panels and peripherals. The Message Display indicates how many Distributed Panels have been found and all event buffers are cleared.
The 'Power' indicator is on as long as there is power available to the HMB Master Panel.
The 'Alarm' indicator will be on whenever an Evacuation Signal or Alert Signal is active.
The 'Fault' indicator will be on (blinking) whenever a fault has occurred in the HMB system. The Message display will indicate a code for the fault that has occurred. In addition, the audible fault signal will be active (beep tone) as long as the fault persists. The 'Fault Silence' switch can be used to silence the audible fault indication, but the visual indicator can only be cleared by an HMB system Reset. If the fault is cleared manually the yellow led indicator can be cleared with a single click of the reset switch.
The 'All-Call' switch will select all available Evacuation/Paging zones on the Paging/Zone Control panel when clicked. Individual paging zones may be deselected using the Paging/Zone Control switches, but a second click of the 'All-Call' switch will deselect the remainder.
The 'System Reset' switch will clear the Master Panel back to it's power on condition but will not cause the system to rerun the 'Power On Diagnostics' program (see 'Global Reset' below). After the 'System Reset' has run its course any Evacuation or Alert Signal that has been input will be reprocessed.
The 'System Reset' switch must be clicked twice within a two second interval to take effect.
A 'Global Reset' can be initiated by holding the "Fault Silence" switch in the up position while the 'System Reset' switch is clicked twice. This will rerun the 'Power On Diagnostics' program. Observe the message display during the reset. It will display +0 then the number of Distributed panels in the communication loop of the HMB system.

EVX 25(E) / 50(E) / 100(E) TROUBLE CODES
When a unit goes into a Trouble Condition, the Yellow LED will remain on until the trouble is cleared. The Green LED will flash a Code to indicate the type of Trouble Condition. There will be a pause between repeats of the code. When multiple Trouble Conditions occur at the same time, the codes will add together.
The number of flashes and associated Trouble Condition are listed below.
Code Trouble
| 1 | Power Failure | 8 | Amplifier Trouble |
| 2 | Open Speaker Circuit | 16 | Microphone Trouble |
| 4 | Shorted Speaker Circuit | 32 | Battery Trouble |
| 6 | External Trouble / Ground Fault |
* 6 flashes typically indicates "External Trouble", such as an EVX-RM. If LED 4 is on, the 6 flash indicates a ground fault. If both a ground fault condition and an external trouble occur simultaneously, the fault codes will not combine for 12 flash.

*Battery input current measurements are determined by test conditions. Two values are shown. First value reflects the unit with a full speaker load and no auxiliary load. Second value reflects the unit with a full speaker load and a full auxiliary load of 0.5A in Standby and 0.75A in Alarm. Your actual load will vary depending on which and how many auxiliary devices, ie...Zone Splitter, Remote Mic, Relays,...etc., are used. Insure that any current draw from an aux device is added into your final battery calculation.
**Input current measurements are determined by test conditions under UL 1711. Sine represents measurements made while the unit produces a continuous non-distorted sine wave of 1 KHz into the rated load of 25 / 50 / 100W at rated output voltage. Alarm is the average current the unit experiences delivering an alarm signal, Temporal Whoop, to the rated load. Standby is the current draw of the unit with all normal power on and aux., terminals fully loaded. Battery Standby is current draw from the batteries on loss of power and otherwise normal standby.
TESTING
Per NFPA 72 Chapter 7, 100% system test is required, at a minimum, annually. Additional testing may be required by the Local Jurisdiction.
