Function/Description
12 or 24VDC from power supply.
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 (standby)
and supply power to all terminals marked Pos (+) DC output (alarm).
Applying voltage to terminals marked Neg(-) input Pos (+) FACP signaling output in
polarity shown will yield the same results as initiating trigger (mentioned above).
Supplies constant negative (-) voltage.
Supplies positive (+) voltage when dry input or fire alarm (wet) trigger input.
Supplies positive (+) voltage in normal condition.
Power is removed when either input trigger is activated.
When the MOM5 is triggered the C and N.O. terminals will close and the
C and N.C. terminals will open. This output is used to trip auxiliary devices.
e.g. HVAC Shutdown, Elevator Recall etc...
Form "C" contacts used for signaling when no voltage is present at -- DC input +
terminals. Under normal conditions, terminals N.O. and C are open, N.C. and C are
closed. A occurance of trouble condition causes N.O. and C to closed and
N.C. and C to open.
