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 EMC series of dual channel exit device sequencers may be used with the S6000FE, S6000PE, or LR100 series electric latch retraction (ELR) devices to provide a delayed signal to operate an automatic door operator or when powering a pair of ELR devices from a single SDC 600 series power supply. Each sequencer channel provides an output to power the ELR device and a “delayed” dry auxiliary output for activation of an automatic door operator. All outputs are field selectable as normally open or normally closed.
