ACM4 series
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 (ACM4/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. 4):
(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].
