Power Supply Board Terminal Identification:
Terminal Legend
Function/Description
L, G, N
Connect 115VAC 60Hz to these terminals: L to hot, N to neutral .
+ DC –
Maximal11D - 12VDC @ 3 .5A or 24VDC @ 2 .7A to ACM8CB boards (power-limited) .
Maximal33D - 12VDC @ 5 .5A or 24VDC @ 5 .7A to ACM8CB boards (power-limited) .
Maximal55D - 12VDC @ 9 .5A to ACM8CB boards (power-limited) .
Maximal77D - 24VDC @ 9 .7A to ACM8Cb boards (power-limited) .
Maximal75D - one (1) 12VDC @ 9 .5A power supply to ACM8CB board (power-limited)
and one (1) 24VDC @ 9 .7A power supply to ACM8CB board (power-limited) .
AC FAIL
NC, C, NO
Indicates loss of AC power . To meet with UL requirements it is mandatory to connect
visual notification devices, connecting audible notification devices is optional . Relay nor-
mally energized when AC power is present . Contact rating 1A @ 28VDC . AC or brown-
out 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
Maximal11D)
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 pir’s, 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),
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 (not evaluated by UL) .
