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
(Enclosure Dimensions, pg. 15).
2. The power supply is pre-wired to the ground (chassis). Connect main incoming ground to the provided green
grounding conductor lead. Connect unswitched AC power (115VAC 60Hz) to the terminals marked [L, N] on power
supply board. 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. 11-13).
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 Maximal3 power supply
(Figs. 1 and 1a, pg. 7). Maximal5 power supply is factory set at 12VDC and Maximal7 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. 8):
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 the terminal marked [NC].
Connect the negative (-) input of the access control devices to the terminal marked [COM].
(b) Fail-Secure Switched Power outputs:
For Fail-Secure operation connect the positive (+) input of the access control devices to the terminal marked [NO].
Connect the negative (-) input of the access control devices to the 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 the terminals marked [C] positive (+) and [COM]
negative (-).
7. Input trigger options (Fig. 2, pg. 8):
(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 the terminals marked [IN] and [GND].
(b) Open Collector Sink inputs:
Connect the access control panel open collector sink positive (+) to the terminals marked [IN] and the negative (-) to
terminals marked [GND].
8. Fire Alarm Interface options (Figs. 8-12, pg. 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
open the
corresponding switch(es) [SW1-SW8] on each ACM8 board. To disable FACP disconnect for an
output close the corresponding switch(es) [SW1-SW8] on each ACM8 board.
(a) Normally Open [NO] input:
For non-latching hook-up refer to (Fig. 9, pg. 14). For latching hook-up refer to (Fig. 10, pg. 14).
(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).
