ACM4E/ACM4CBE Installation Guide
- 3 -
Installation Instructions:
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure’s upper keyholes over the two upper screws; level and secure. Mark the position of the lower
three holes. Remove the enclosure. Drill the lower holes and install the two fasteners. Place the enclosure’s
upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws

2. Power supply input:
The units can be powered with one (1) power supply which will provide power for both board operation and
the locking devices or two (2) separate power supplies, one (1) to provide power for the board operation and
the other to provide power for the locking devices and/or access control hardware.
Note:
The input power can be either 12 to 24 volts AC or DC
(0.4A @ 12 volt, 0.2A @ 24 volt current consumption with all relays energized).
a) Single power supply input:
If the unit and the locking devices are to be powered using a single Listed Access Control Power Supply,
connect the output (12 to 24 volts AC or DC) to the terminals marked [– C].
b) Dual power supply inputs
(Fig. 1, pg. 5)
:
When the use of two Listed Access Control Power Supplies is desired, jumpers J1 and J2 (located to the
left of the power/control terminals) must be cut. Connect power for the unit to the terminals marked
[– C] and connect power for the locking devices to the terminals marked [– Power +].
Note:
When using DC Listed Access Control Power Supplies polarity must be observed.
When using AC Listed Access Control Power Supplies polarity need not be observed.
Note:
For UL compliance the power supplies must be UL Listed for Access Control Systems and accessories.

Output options
(Fig. 1, pg. 5)
:
The ACM4E will provide either four (4) switched power outputs, four (4) dry form “C” outputs, or any
combination of of both switched power and form “C” outputs, plus four (4) unswitched auxiliary power outputs.
The ACM4CBE will provide four (4) switched power outputs or four (4) unswitched auxiliary power outputs.
a) Switched Power outputs:
Connect the negative (–) input of the device being powered to the terminal marked [COM]. For Fail-Safe
operation connect the positive (+) input of the device being powered to the terminal marked [NC]. For
Fail-Secure operation connect the positive (+) input of the device being powered to the terminal marked [NO].
b) Form “C” outputs
(ACM4E)
:
When form “C” outputs are desired the corresponding output fuse (1-4) must be removed. Connect
negative (–) of the power supply directly to the locking device. Connect the positive (+) of the power supply
to the terminal marked [C]. For Fail-Safe operation connect the positive (+) of the device being powered to
the terminal marked [NC]. For Fail-Secure operation connect the positive (+) of the device being powered
to the terminal marked [NO].
c) Auxiliary Power outputs (unswitched):
Connect positive (+) input of the device being powered to the terminal marked [C] and the negative (–) of
the device being powered to the terminal marked [COM]. Output can be used to provide power for card
readers, keypads etc.
Note:
When wiring for power-limited outputs utilize a knockout separate from the one used for
non power-limited wiring.
4.
Input trigger options
(Fig. 1, pg. 5)
:
a) Normally Open [NO] input trigger:
Inputs 1-4 are activated by normally open or open collector sink inputs.
Connect devices (card readers, keypads, request to exit buttons etc.) to terminals marked [IN] and [GND].
b) Open Collector Sink inputs:
Connect the access control panel open collector output to the terminal marked [IN] and the
common (negative) to the terminal marked [GND].
