Overview:
These units are UL Listed Sub-Assembly multi-output Access Power Controllers that convert one (1) 12 to 24 volt DC
input into eight (8) independently controlled fused or PTC protected outputs. These power outputs can be converted to dry
form “C” contacts (fused models only). Outputs are activated by an open collector sink or normally open [NO] dry trigger
input from an Access Control System, Card Reader, Keypad, Push Button, PIR, etc. The units will route power to a variety
of access control hardware devices including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. Outputs will operate in both Fail-Safe and/or Fail-Secure modes. Units are designed to be powered by one common power source which
will provide power for both the board operation and locking devices, or two (2) totally independent power sources, one
(1) providing power for board operation and the other for lock / accessory power. The FACP Interface enables Emergency
Egress, Alarm Monitoring, or may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the eight (8) outputs.

Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local
codes and authorities having jurisdiction. Product is intended for indoor use only and should be installed
by qualified personnel.
1. Refer to Sub-Assembly Installation Instruction for mounting Rev. MS050913.
Carefully review:
Typical Application Diagram (pg. 4) Terminal Identification Table (pg. 5)
LED Diagnostics (pg. 5) Hook-up Diagrams (pg. 6)
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 12 to 24 volts DC (0.5A @ 12 volt, 0.3A @ 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 power supply, connect the output
(12 to 24 volts DC) to the terminals marked [- Power +].
(b) Dual power supply inputs (Fig. 1c, pg. 4):
When the use of two 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 [- Power +] and connect power for the
locking devices to the terminals marked [- Control +].
Note: When using DC power supplies polarity must be observed. When using AC power supplies polarity
needs not to be observed (Fig. 1d, pg. 4).
Note: For UL compliance the power supplies must be UL Listed for Access Control Systems and accessories.
3. Output options (Fig. 1, pg. 4):
The ACM8 will provide either eight (8) switched power outputs, eight (8) dry form “C” outputs, or any combination
of of both switched power and form “C” outputs, plus eight (8) unswitched auxiliary power outputs.
The ACM8CB will provide eight (8) switched power outputs or eight (8) 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:
When form “C” outputs are desired the corresponding output fuse (1-8) must be removed (ACM8 only). 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.
4. Input trigger options (Fig. 1, pg. 4):
(a) Normally Open [NO] input trigger:
Inputs 1-8 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 sink positive (+) to the terminal marked [IN] and the
negative (-) to the terminal marked [GND].
5. Fire Alarm Interface options (Figs. 3 through 7, pg. 6):
A normally closed [NC], normally open [NO] input or polarity reversal input from FACP signaling circuit will
trigger selected outputs. To enable FACP Disconnect for an output turn the corresponding switch [SW1-SW8] OFF.
To disable FACP disconnect for an output turn the corresponding switch [SW1-SW8] ON.
(a) Normally Open [NO] input:
For non-latching hook-up (Fig. 4, pg. 6). For latching hook-up (Fig. 5, pg. 6).
(b) Normally Closed [NC] input:
For non-latching hook-up (Fig. 6, pg. 6). For latching hook-up (Fig. 7, pg. 6).
