Altronix MOM5C Installation Instructions - Manual (Page 2)

LED Diagnostic Table:
LED ON OFF
Power (Green) Normal operation. Loss of power to MOM5.
Trigger (Green) MOM5 triggered (alarm condition). MOM5 in stand-by (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 2.2K 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 + Applying voltage to terminals marked [-- Input +] from the FACP signaling circuit in
polarity shown will yield the same results as initiating trigger (mentioned above).
NEG1 thru NEG5 Supplies constant negative (-) voltage.
POS (+) DC OUTPUT Supplies positive (+) voltage when either input trigger is activated.
(ALARM)
POS (+) DC OUTPUT Supplies positive (+) voltage in normal condition.
(STANDBY) Power is removed when either input trigger is activated.
NC, C, NO When the MOM5 is triggered the terminals marked [C and NO] will close and the
DRY OUTPUT 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 Form “C” contacts used for signaling when no voltage is present at [-- DC input +]
POWER FAIL terminals. Under normal conditions, terminals marked [NO and C] are open,
and terminals marked [NC and C] are closed. A occurrence of trouble condition causes
terminals marked [NO and C] to closed and [NC and C] to open.
