LED Diagnostic Table:
LED ON OFF
Power (Green) Normal operation. Loss of power to MOM5.
Trigger (Green) MOM5 triggered (alarm condition). MOM5 in standby (non-alarm condition).
Outputs (Red) Output tripped due to a short circuit or overload condition. Normal operation.
Terminal Identification:
Terminal Legend Function/Description
– DC Input + 12VDC or 24VDC from power supply.
Trigger This circuit is supervised by a 2.2 K EOL resistor. Initiating a short or open will cause
power to be dropped to all terminals marked Pos. (+) DC output (stand-by) and supply
power to all terminals marked Pos (+) DC output (alarm).
Input Neg (–),
Pos (+) Applying voltage to terminals marked Neg (-) input Pos (+) FACP signaling output in
polarity shown will yield the same results as initiating trigger (mentioned above).
Neg (–) 1 thru 5 Supplies constant negative (-) voltage.
Pos (+) DC output (alarm) Supplies positive (+) voltage when dry input or fire alarm (wet) trigger input.
Pos (+) DC output
(stand-by) Supplies positive (+) voltage in normal condition. Power is removed when either input
trigger is activated.
NC, C, NO
Dry output When the MOM5 is triggered terminals marked [C and NO] will close and the terminals
marked [C and NC] will open. This output is used to trip auxiliary devices. e.g. HVAC
Shutdown, Elevator Recall etc.
NC, C, NO
Power Fail Form “C” contacts used for signaling when no voltage is present at – DC input +
terminals. Under normal conditions, terminals marked [NO and C] are open, [NC and C]
are closed. An occurance of trouble condition causes terminals marked [NO and C] to
close and terminals marked [NC and C] to open.
