8. ACM8CB Fire Alarm Interface options (Figs. 6-10, pg. 10):
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] OFF on each ACM8CB board. To disable FACP
disconnect for an output turn the corresponding switch(es) [SW1-SW8] ON on each ACM8CB board.
(a) Normally Open [NO] input:
For non-latching hook-up refer to Fig. 7, pg. 10. For latching hook-up refer to Fig. 8, pg. 10.
(b) Normally Closed [NC] input:
For non-latching hook-up refer to Fig. 9, pg. 10. For latching hook-up refer to Fig. 10, pg. 10.
(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. 6, pg. 10).
9. FACP Dry form "C" output (Fig. 2b, pg. 7) (Not evaluated by UL):
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 board.
10. Stand-by Battery Connections (Fig. 3, pg. 8):
For U.S. Access Control applications batteries are optional. Batteries are required for Canadian installations
(ULC-S319). When batteries are not used, a loss of AC will result in the loss of output voltage. When the
use of stand-by batteries is desired, they must be lead acid or gel type.
Connect battery to terminals marked [– BAT + ] (Fig. 3, pg. 8). Use two (2) 12VDC batteries connected in
series for 24VDC operation (battery leads included). Use batteries - Casil CL1270 (12V/7AH), CL12120
(12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL recognized BAZR2 and
BAZR8 batteries of an appropriate rating.
11. Battery and AC Supervision outputs (Fig. 3, pg. 8):
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. To delay AC reporting for 2 hrs. set dip switch [AC Delay] to OFF position (Fig. 3, pg. 8).
To delay AC reporting for 1 min. set dip switch [AC Delay] to ON position (Fig. 3, pg. 8).
13. Fire Alarm Disconnect (Fig. 3, pg. 8):
To enable Fire Alarm Disconnect set dip switch [Shutdown] to ON position.
To disable Fire Alarm Disconnect set dip switch [Shutdown] to OFF position.
14. Installation of tamper switch (Fig. 3a, pg. 8):
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 (Fig. 3a, pg. 8).
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.
15. Multiple power supply inputs (Fig. 2, pg. 7) (Not evaluated by UL):
When using an additional Listed external power supply, jumpers J1 and J2 located on corresponding
ACM8CB board must be cut (Fig. 2c, 2d, pg. 7 and Fig. 5, pg. 10). Connect external Listed power-limited
access control power supply to the terminals marked [– Power +] (These terminals are paralleled to the
[– Control +] terminals). When using DC power supplies, polarity must be observed. When using AC
power supplies, polarity need not be observed. (Fig. 2d, pg. 7) All field wiring connections must
be made employing suitable gauge CM or FPL jacketed wire (or equivalent substitute) (Fig. 4a, pg. 9).
