Local Silence/Acknowledge Switch.
Performs multiple functions:
•
When pressed, it first lights all the LEDs on the
ACM-32A Series control module (except the
On-line LED) and then each expander. Piezo sounds for as long as the switch is held down.
•
It acknowledges all status changes for both the annunciator and the expanders. Flashing LEDs will latch on solid
and the piezo will be silenced.
On-line LED.
Flashes green during communication with the control panel.
System Trouble LED.
Glows yellow for all trouble conditions in the system, including points or zones not mapped to the
annunciator/expanders. Flashes if communication with control panel is broken.
Point-Active LED.
Flashes to indicate an active point; after being acknowledged it glows until reset. LED color varies by
model number; see chart below.

Color of Point-active LED

NOTE:
Loss of communication with the control panel is monitored and reported by the ACM-32A. If connection between ACM-32A and
AEM-32A fails, the ACM-32A will show a trouble condition and the main control panel will show annunciator-point trouble.
