1. Mount unit in 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. Connect unswitched AC power (220VAC 50/60Hz) to terminals marked [L, N] (Fig. 3, pg. 10).
Use 14 AWG or larger for all power connections. Secure green wire lead to earth ground lug.
Keep power-limited wiring separate from non power-limited wiring.
Minimum 0.25” spacing must be provided.
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 power supply board
(Maximal11FV and Maximal33FV, Fig. 1, pg. 9). Maximal55F power supply is factory set at 12VDC.
Maximal77F power supply is factory set at 24VDC. Maximal75F consists of one (1) power supply board
that is factory set at 12VDC, and one (1) power supply board that 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. 9):
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.
ACM8 Auxiliary Power outputs (unswitched):
Connect access control devices that require constant power to terminals marked [C] positive (+) and [COM]
negative (–). Outputs can be used to provide power for card readers, keypads etc.
eFlow Auxiliary outputs (unswitched):
For auxiliary device connection this output will not be affected by Low Power Disconnect or Fire Alarm
Interface. Connect device to terminals marked [+ AUX –] (Fig. 3, pg. 10).
7.
Input trigger options (Fig. 2, pg. 9):
(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.
ACM8 Fire Alarm Interface options (Figs. 5-9, pg. 10):
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.
