Model Description
PM8 PM8 Power Module with (8) 2.0 A replaceable fuses, standard 3AG (1/4" x 1-1/4").
PM8R PM8 Power Module with (8) 2.5 A PTC auto-resettable fuses.
DAC8, DAC8R Direct Access Controller
  • Distributes Door Lock Power to 8 Fused or PTC Outputs
  • Outputs Directly controlled by an Access Control System
    (no relay isolation)
  • Fail-Safe or Fail-Secure selectable per Output
  • Low Power FACP Interface for Emergency Power Disconnect
  • Low Power replaceable Disconnect Relay with Aux Contacts
  • For operation to 30VAC/DC , 8 Amps
  • Small Footprint PCB - 3.0”w x 6.0”h
  • Includes Mounting Hardware, Relays, Fuses, Manual
The DAC8 distributes power to 8 door locks directly controlled by an Access Control System (without isolation relays). Each Module includes a low power Disconnect Relay that drops power to fail-safe locks when interfaced to a fire or life safety system. A Red LED is provided for easy visual identification of an energized relay. Aux contact terminals are provided for monitoring the FACP interface. Powerful features in a small footprint - only 3.0 x 6.0 inches.

MAC8 and MAC8R

MAC4 and MAC4R

The MAC Modules distribute power to lock outputs controlled by an Access Control System through isolation relays. Inputs activated by Access System dry contacts or sink outputs. Use common or separate Output Power and Control Power inputs. Outputs jumper selectable for Fail-Safe, Fail-Secure, Dry Contact or Fused-Output-Only. FACP Interface with many hookup options. All relays are depluggable/replaceable. Low current draw. Red relay status led indicators. Extreme features in small footprints.

Selectable and Reconfigurable

Each output has a simple removable jumper that is easily positioned to select the outputs' operation;
D = use Disconnect Power
C = use Continuous Power
X = use Dry Relay Contact

Output can also be used as Fused-Output-Only whether or not a Relay is installed in the Output's relay socket. This powered output can be Fail-Safe or Fail-Secure by setting the jumper described above.
