reported within 1 minute of event. To delay reporting of up to 6 hrs.,
cut "AC delay" jumper and reset power to unit.
Used to indicate low battery condition, e.g. connect to alarm panel. Relay normally energized when
DC power is present. Contact rating 1 amp @ 28VDC. A removed battery is reported within 5 minutes.
BAT FAIL
Battery reconnection is reported within 1 minute.

Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC (N/A for AL1024ULACM),
24VDC output threshold set @ approximately 21VDC (N/A for AL1012ULACM).

Function/Description
12VDC or 24VDC input from power supply board.
These terminals can be connected to a separate power-limited, UL Listed power supply to
provide isolated operating power for the ACM8 (jumpers J1and J2 Must be removed).
From normally open and/or open collector sink trigger inputs
(request to exit buttons, exit pir's, etc.).
12 to 24 volts AC/DC trigger controlled outputs:
Fail-Safe [NC positive (+) & COM Negative (-)],
Fail-Secure [NO positive (+) & COM Negative (-)],
Auxiliary output [C positive (+) & COM Negative (-)]
(When using AC power supplies polarity need not be observed),
NC, C, NO become form "C" 5 amp 24VAC/VDC rated dry outputs when fuses are
removed. Contacts shown in a non-triggered state.
Fire Alarm Interface trigger input from FACP. Trigger inputs can be normally open,
normally closed from an FACP output circuit (Fig. 4 through 8, pg. 8).
Form "C" relay contact rated @ 1 amp 28VDC for alarm reporting.
(This output has not been evaluated by UL).
