5 .
Output options (Fig. 2, pg. 9):
The unit will provide sixteen (16) switched power outputs .
(a) Fail-Safe Switched Power outputs:
For Fail-Safe operation connect the positive (+) input of the access control devices to terminal marked
[NC] . Connect the negative (–) input of the access control devices to terminal marked [COM] .
(b) Fail-Secure Switched Power outputs:
For Fail-Secure operation connect the positive (+) input of the access control devices to terminal marked
[NO] . Connect the negative (–) input of the access control devices to terminal marked [COM] .
6 .
Auxiliary Power outputs (unswitched):
Connect access control devices that require constant power to terminals marked [C] positive (+) and
[COM] negative (–) .
7 .
Input trigger options (Fig. 2, pg. 9):
(a) Normally Open [NO] input trigger:
Inputs 1-8 are activated by normally open or open collector sink inputs .
Connect access control panel outputs, keypads, push buttons, REX PIRs, etc . to terminals marked [IN]
and
[GND] .
(b) Open Collector Sink inputs:
Connect the access control panel open collector sink positive (+) to terminals marked [IN] and the
negative (–) to terminals marked [GND] .
8 .
Fire Alarm Interface options (Figs. 10-15, pg. 17-18):
A normally closed [NC] or normally open [NO] input trigger from a fire alarm control panel or a polarity
reversal input from an FACP signaling circuit will affect selected outputs . To enable FACP Disconnect for
an output turn the corresponding switch(es) [SW1-SW8] on each ACM8CB board OFF . To disable FACP
disconnect for an output turn the corresponding switch(es) [SW1-SW8] on each ACM8CB board ON .
(a) Normally Open [NO] input:
For non-latching hook-up refer to Fig. 12, pg. 17 . For latching hook-up refer to Fig. 13, pg. 18 .
(b) Normally Closed [NC] input:
For non-latching hook-up refer to Fig. 14, pg. 18 . For latching hook-up refer to Fig. 15, pg. 18 .
(c) FACP Signaling Circuit input trigger:
Connect the positive (+) and negative (–) from the FACP signaling circuit output to the terminals marked
[+ INP –] . Connect the FACP EOL to the terminals marked [+ RET –] (polarity is referenced in an alarm
condition) . Jumper located next to TRG LED must be cut (Fig. 2b, pg. 8 and Fig. 8, pg. 14) .
9 .
FACP Dry form “C” output (Fig. 2a, pg. 9):
FACP form “C” contacts can be use to trigger reporting or signaling devices . These contact switch
upon a fire alarm input trigger to the ACM8CB boards .
10 .
Stand-by Battery Connections (Figs. 3-5, pgs. 10-12):
For Access Control applications batteries are optional . If batteries are not used a loss of AC will result in
the loss of output voltage . Batteries must be lead acid or gel type . Connect one (1) 12VDC battery to the
terminals marked [+ BAT –] for 12VDC operation (Figs. 3, 5, pgs. 10, 12) . Use two (2) 12VDC batteries
wired in series for 24VDC operation (Figs. 3-5, pgs. 10-12) .
11 .
Battery and AC Supervision outputs (Figs. 3-5, pgs. 10-12):
It is required to connect supervisory trouble reporting devices to outputs marked [AC Fail, BAT FAIL]
supervisory relay outputs marked [NC, C, NO] to appropriate visual notification devices . Use 22 AWG to
18 AWG for AC Fail & Low/No Battery reporting .
12 .
Installation of tamper switch (Not Included) (Figs. 3a, 4a, 5a, pgs. 10-12):
Mount UL Listed tamper switch (Altronix Model TS112 or equivalent) at the top of the enclosure . Slide
the tamper switch bracket onto the edge of the enclosure approximately 2” from the right side . Connect
tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device .
To activate alarm signal open the door of the enclosure .
13 .
Multiple power supply inputs (Fig. 2, pg. 9):
When using an additional UL Listed external power supply, jumpers J1 and J2 located on corresponding
ACM8CB boards must be cut (Fig. 2c, 2d, pg. 9, Fig. 10, pg. 17) . Connect external UL Listed power-limited
access control power supply to the terminals marked [– C] (only applicable on Maximal11D) . When
using DC power supplies polarity must be observed . When using AC power supplies polarity needs not to
be observed . (Fig. 2d, pg. 9). All field wiring connections must be made employing suitable gauge CM or
FPL jacketed wire or equivalent substitute (Fig. 6a-9a, pgs. 13-16).
