Door control relay modules ensure compatibility of access hardware components and simplify system installation and troubleshooting. Modules may be ordered with or without power supplies. Different modules may be specified for one power supply. The isolated relay design allows small gauge cable runs of 22 gauge wire up to 1000 feet from the trigger device to the module.

Modules may be ordered with or without power supplies. Different function modules may be used in the same power supply or cabinet.

SDC’s ACM-1 series allows for control of a single electrified locking device from up to six activation devices. LED visual status indicators provide relay activation status.
