Introduction
The Access Control Module (DGP-ACM12) is designed to be used with the
Digiplex EVO System control panels. Each DGP-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 4.1
• The backlight intensity defaults in sections [025] and [026] are now 003
What’s New 4.0
• Allows access with Card and Pin and Card or PIN when used with a
DGP-R915 or CR-R885-BL
• Allows arming with PIN or Card and PIN when used with a DGP-R915
• Transformer Sharing: Use one transformer to power multiple modules
with transformer sharing. Respect the maximum power output of the
transformer. See Figure 1 for more information.
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
9
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 DGP-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.
