1 . Mount unit in the desired location . Mark and predrill holes in the wall to line up with the top three keyholes
in the enclosure . Install three upper fasteners and screws in the wall with the screw heads protruding . Place
the enclosure’s upper keyholes over the three upper screws, level and secure . Mark the position of the lower
three holes . Remove the enclosure . Drill the lower holes and install the three fasteners . Place the enclosure’s
upper keyholes over the three upper screws . Install the three lower screws and make sure to tighten all screws
(Enclosur Dimensions, pg. 16) .
2 . Connect unswitched AC power (220VAC 50/60Hz) to the terminals marked [L, N] on power supply board .
Green branch wire connects to earth (safety) ground lug . Use 14 AWG or larger for all power connections .
Keep power-limited wiring separate from non power-limited wiring. Minimum 0.25” spacing must
be provided (Figs. 5-7, pgs. 10-12).
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or
servicing equipment. There are no user serviceable parts inside. Refer installation and servicing to
qualified service personnel.
3 . Select desired DC output voltage by setting SW1 to the appropriate position on the Maximal3V power
supply,
(Figs. 1 and 1a, pg. 7). Maximal5V power supply is factory set at 12VDC and Maximal7V power
supply is factory set at 24VDC .
4 . Measure the output voltage of the unit before connecting any devices to ensure proper operation .
Improper or high voltage will damage these devices .
5 .
Output options (Fig. 2, pg. 7):
The unit will provide either sixteen (16) switched power outputs, sixteen (16) dry form “C” outputs, or any
combination of both switched power and form “C” 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] .
(c) Form “C” outputs:
When form “C” outputs are desired the corresponding output fuses (1-8) of each ACM8 board must
be removed .
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. 7):
(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. 8-12, pgs. 13-14):
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 ACM8 board . To disable FACP
disconnect for an output turn the corresponding switch(es) [SW1-SW8] ON on each ACM8 board .
(a) Normally Open [NO] input:
For non-latching hook-up refer to Fig. 9, pg. 13 . For latching hook-up refer to Fig. 10, pg. 13 .
(b) Normally Closed [NC] input:
For non-latching hook-up refer to Fig. 11, pg. 14 . For latching hook-up refer to Fig. 12, pg. 14 .
(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. 2a, pg. 7, Fig. 8, pg. 13) .
