Function/Description
L, N
Connect 220VAC 50/60Hz to these terminals: L to hot, N to neutral.
+ DC –
Maximal11DV -
12VDC @ 3.5A or 24VDC @ 2.7A to ACM8CB boards.
Maximal33DV -
12VDC @ 5.5A or 24VDC @ 5.7A to ACM8CB boards.
Maximal55DV -
12VDC @ 9.5A to ACM8CB boards.
Maximal77DV -
24VDC @ 9.7A to ACM8Cb boards.
Maximal75DV -
one (1) 12VDC @ 9.5A power supply to ACM8CB board and
one (1) 24VDC @ 9.7A power supply to ACM8CB board.
AC FAIL
NC, C, NO
Indicates loss of AC power. Relay normally energized when AC power is present.
Contact rating 1A @ 28VDC. AC or brownout fail is reported within 1 minute of event.
BAT FAIL
NC, C, NO
Indicates low battery condition, e.g. connect to access control panel. Relay normally
energized when DC power is present. Contact rating 1A @ 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.
24VDC output threshold set @ approximately 21VDC.
+ BAT –
Stand-by battery connections. Connect one (1) 12VDC battery to the terminals marked
[+ BAT –] for 12VDC operation
(Fig. 3, pg. 10, Fig. 5, pg. 12)
. Use two (2) 12VDC
batteries wired in series for 24VDC operation
(Figs. 3-5, pgs. 10-12)
.
Access Power Controller Terminal Identification:
Terminal Legend
Function/Description
– Power +
12VDC or 24VDC input from power supply board.
– C
(only applicable for
Maximal11DV)
These terminals can be connected to an external UL Listed power-limited access control
power supply to provide isolated operating power for the ACM8CB (jumpers J1 and J2
must be removed). All field wiring connections must be made employing suitable gauge
CM or FPL jacketed wire (or equivalent substitute),
(Figs. 6a-9a, pgs. 13-16).
TRIGGER INPUT 1 -
INPUT 8 IN, GND
From normally open and/or open collector sink trigger inputs
(request to exit buttons, exit PIRs, etc.)
OUTPUT 1 -
OUTPUT 8
NC, C, NO, COM
12VDC to 24VDC 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 convert to dry form “C” 5A 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 signaling circuit output
(Figs. 10-15, pg. 17, 18).
FACP INTERFACE
NC, C, NO
Form “C” relay contact rated @ 1A/28VDC for alarm reporting.
