MOM-4
Monitored Output Module
Description
The MOM-4 module provides a programmable source of power to control and operate output
devices including notification appliances and releasing devices. Additionally, it continuously
supervises wiring connected to terminals A+, A- for open or short circuits and 24+ and 24- when
24VDC is applied.
MOM-4 employs one red LED to indicate the status. In normal condition, the LED flashes. When the
output is activated, the LED will turn on constantly. In case of trouble, the LED will turn off.
Since the system allows maximum 13 LEDs on devices to turn on constantly, if system already has
13 lighted LEDs on devices, MOM-4 will not turn on the LED and keep flashing even if the output
of MOM-4 is activated.
