L, G, N
Connect 115VAC 60Hz to these terminals: L to hot, N to neutral, G to ground.
- DC +
AL300ULM - 12VDC/24VDC @ 2.5 amp to MOM5 board (power limited).
AL400ULM - 12VDC @ 4 amp or 24VDC @ 3 amp to MOM5 board (power limited).
AL600ULM - 12VDC/24VDC @ 6 amp to MOM5 board (non-power limited).
AL1012ULM - 12VDC @ 10 amp to MOM5 board (non-power limited).
AL1024ULM - 24VDC @ 10 amp to MOM5 board (non-power limited).
AC FAIL
Indicates loss of AC power, e.g. connect to audible device or alarm panel. Relay
NO, C, NC
normally energized when AC power is present. Contact rating 1 amp @ 28VDC.
AC or brownout fail is reported within 1 minute of event. To delay reporting of up to
6 hrs., cut “AC delay” jumper and reset power to unit.
BAT FAIL
Indicates low battery condition, e.g. connect to alarm panel. Relay normally
NO, C, NC
energized when DC power is present. Contact rating 1 amp @ 28VDC.
A removed battery is reported within 5 minutes. Battery reconnection is reported
within 1 minute.
Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC (N/A for AL1024ULM),
24VDC output threshold set @ approximately 21VDC.
+ BAT -
Stand-by battery connections. AL300ULXB, AL400ULXB and AL600ULXB (Power Supply
Board) maximum charge current is .7 amp. AL1024ULXB (Power Supply Board)
maximum charge current is 3.6 amp.
MOM5 - Output Module
Terminal Legend
Function/Description
--- DC INPUT +
12VDC or 24VDC from power supply.
TRIGGER
Dry normally open [NO] or normally closed [NC] supervised (2.2K EOL resistor)
input trigger. A short or open circuit will transfer power from terminals marked
[POS. (+) DC OUTPUT (STAND-BY)] to terminals marked
[POS (+) DC OUTPUT (ALARM)].
--- INPUT +
Wet (5-30VDC) input trigger. Applying voltage to these terminals in the polarity shown
will transfer power from terminals marked [POS. (+) DC OUTPUT (STAND-BY)] to
terminals marked [POS (+) DC OUTPUT (ALARM)] (e.g. fire alarm control panel
indications circuit).
NEG 1 THRU NEG 5
Supplies constant negative (-) voltage.
POS (+) DC OUTPUT
Supplies positive (+) voltage when dry trigger input or fire
(ALARM) 1-5
alarm wet trigger input is applied.
POS (+) DC OUTPUT
Supplies positive (+) voltage in normal condition.
(STAND-BY) 6-10
Power is removed when dry trigger input or fire alarm wet trigger input is applied.
NC, C, NO
When the MOM5 is triggered the terminals marked [C and NO] will open and the
DRY OUTPUT
terminals marked [C and NC] will close. This output is used to trigger auxiliary devices.
(e.g. HVAC Shutdown, Elevator Recall etc.) Contact rating 1 amp @ 28VDC.
NC, C, NO
Form “C” contacts used for reporting no voltage is present at [-- DC input +]
POWER FAIL
terminals. Under normal conditions, terminals marked [NO and C] are open, [NC and C]
are closed. A loss of power causes terminals marked [NO and C] to close and [NC and C]
to open. Contact rating 1 amp @ 28VDC.
