Function/Description
L, N Connect 115VAC 60Hz to these terminals: L to hot, N to neutral.
+ DC –
AL400ULACMCB - 12VDC @ 4 amp or 24VDC @ 3 amp to ACM8CB board (power-limited).
AL600ULACMCB - 12VDC/24VDC @ 6 amp to ACM8CB board (power-limited).
AL1012ULACMCB - 12VDC @ 10 amp to ACM8CB board (power-limited).
AL1024ULACMCB - 24VDC @ 10 amp to ACM8CB board (power-limited).
AC FAIL
NC, C, NO
Used to notify loss of AC power, e.g. connect to audible device or alarm panel. Relay
normally energized when AC power is present. Contact rating 1 amp @ 28VDC. AC or brownout fail is
reported within 1 minute of event. To delay reporting of up to 6 hrs.,
cut “AC delay” jumper and reset power to unit.
BAT FAIL
NC, C, NO
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.
Battery reconnection is reported within 1 minute.
Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC (N/A for AL1024ULACMCB),
24VDC output threshold set @ approximately 21VDC (N/A for AL1012ULACMCB).
+ BAT –
Stand-by battery connections. AL400ULXB2, AL600ULXB and AL1012ULXB
(Power Supply Board) maximum charge current is 0.7 amp. AL1024ULXB2
(Power Supply Board) maximum charge current is 3.6 amp.
ACM8CB Access Power Controller
Terminal Legend Function/Description
– Power + 12VDC or 24VDC input from power supply board.
– Control +
These terminals can be connected to a separate power limited, UL listed power supply to
provide isolated operating power for the ACM8CB (jumpers J1and J2 Must be removed).
TRIGGER
INPUT 1- INPUT 8
IN, GND
From normally open and/or open collector sink trigger inputs
(request to exit buttons, exit pir’s, etc.).
OUTPUT 1-OUTPUT 8
NC, C, NO, COM
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.
FACP INTERFACE
T, + INPUT –
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).
FACP INTERFACE
NC, C, NO
Form “C” relay contact rated @ 1 amp 28VDC for alarm reporting.
(This output has not been evaluated by UL).
