Introduction
The Access Control Module (ACM12) is designed to be used with the Digiplex EVO
System control panels. Each ACM12 allows you to connect a reader, a REX device, a
door contact and a locking device to control the access to one door. If desired, door
contacts can also be assigned to zones in the control panel to link the doors to the
alarm system. This will allow you to use the same door for the access control
system and the alarm system.
What’s New 4.2
•
Support for six additional schedule intervals for Door Unlock Schedule.
•
Added security when disarming your system. New option to disarm with
access card and PIN code.
Technical Specifications
Installation
The module is connected to the control panel’s combus as shown in Figure 1.
Please refer to the control panel’s Programming Guide for the maximum
installation distance. Devices connected to the PGM output must be connected as
shown in Figure 2. Refer to Figure 5 for connection drawings for the REX device,
reader, locking device and door contact.
The door contact follows the control panel’s EOL definition. When EOL is
enabled and the door contact is not used, place a 1k
resistor across the
CT
and
AUX
- input terminals. If EOL is disabled, use a jumper.
If the REX device is
not used, place a jumper across the
REX
and
AUX
- terminals.
AC Power
Use a 16.5Vac (50/60 Hz) transformer with a minimum 20VA. as shown in
Figure 1. Do not use any switch-controlled outlets to power the transformer.
Backup Battery
To power the module’s door lock relay during a power failure, connect a
12Vdc 4Ah rechargeable acid/lead or gell cell backup battery as shown in
Figure 1. Connect the battery after applying AC power.
Inverting the polarity when installing the battery will blow the battery
fuse.
Connecting the External Negative Trigger
The ACM12 comes with an external negative trigger. You can use a PGM from
the control panel or another module to release the access control door lock.
The external negative trigger can also be triggered using a push-button.
When the push button is pressed, the door will unlock. The PGM or push-
button must ground the negative trigger. Connect the push-button as shown
in Figure 2.

When connecting the diode to the door lock, be sure to
connect the cathode of the diode to the positive (+)
voltage and the anode to the negative (-) voltage.
