LED and Keypad Switch Functions
ACM-16AT, ACM-32A, and Expanders
6.1.6 Trouble LED
Flashes to indicate a trouble situation. After being acknowledged it glows until reset. If communication with control panel is broken,
all
trou-
ble LEDs flash.
6.2 ACM-16AT, ACM-32A, and Expanders
6.2.1 ACM-16AT
6.2.2 AEM-16AT
NOTE:
If the annunciator is set for Flash-inhibit, this LED will be on steady for trouble situations.

Local Silence/Acknowledge Switch.
Performs multiple functions:
When pressed, it first lights all the LEDs on the ACM-16AT 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.
Note:
In systems set for manual override mode, it is used as the manual override key to toggle between automatic
operation or manual override operation for all points.
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.
Note:
In AM2020/AFP1010 systems, this LED may also indicate manual override mode.
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.
Trouble LED.
Flashes to indicate a trouble situation. After being acknowledged it glows until reset. If communication
with control panel is broken,
all
trouble LEDs flash.
LED color varies by model number; see chart below.
Control Switch.
Functions as a local Lamp Test for the two LEDs dedicated to a point. Control switches can be used to
execute such system functions as ACKNOWLEDGE, SIGNAL SILENCE, and SYSTEM RESET. Switches can also be
used to control the states of various output circuits.

Lamp Test Switch.
When pressed, it lights all the LEDs on the AEM-16AT Series expander (except the On-line LED) and
sounds the piezo for as long as the switch is held down.
Inactive LEDs.
These two LEDs are not functional on expander modules.
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.
Trouble LED.
Flashes to indicate a trouble situation. After being acknowledged it glows until reset. If communication with
control panel is broken,
all
trouble LEDs flash.
