Terminal Identification Tables:
Function/Description
Connect 115VAC 60Hz to these terminals: L to hot, N to neutral.
AL300ULM - 12VDC/24VDC @ 2.5A to MOM5 board (power-limited).
AL400ULM - 12VDC @ 4A or 24VDC @ 3A to MOM5 board (power-limited).
AL600ULM - 12VDC/24VDC @ 6A to MOM5 board (power-limited).
AL1012ULM - 12VDC @ 10A to MOM5 board (power-limited).
AL1024ULM - 24VDC @ 10A to MOM5 board (power-limited).
Indicates loss of AC power, e.g. connect to audible device or alarm panel. Relay normally
energized when AC power is present. Contact rating 1A @ 28VDC. AC or brownout fail
is reported within 1 minute of event. To delay reporting for up to 6 hrs., cut "AC delay"
jumper and reset power to the unit.
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized
when DC power is present. Contact rating 1A @ 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.
24VDC output threshold set @ approximately 21VDC.
Stand-by battery connections.
AL300ULXB2, AL400ULXB2, AL600ULXB and AL1012ULXB (Power Supply Board)
maximum charge current is 0.7A.
AL1024ULXB2 (Power Supply Board) maximum charge current is 3.6A.
Function/Description
12VDC or 24VDC from power supply.
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)].
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).
Supplies constant negative (–) voltage.
Supplies positive (+) voltage when dry trigger input or fire alarm wet trigger input
is applied.
Supplies positive (+) voltage in normal condition. Power is removed when dry trigger
input or fire alarm wet trigger input is applied.
When the MOM5 is triggered the terminals marked [C and NO] will open and the
terminals marked [C and NC] will close. This output is used to trigger auxiliary devices.
(e.g. HVAC Shutdown, Elevator Recall etc.). Contact rating 1A @ 28VDC.
Form "C" contacts used for reporting no voltage is present at [– DC INPUT +] 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 1A @ 28VDC.
