Exit Device Sequencer Relays
The EMC Dual Channel Sequencer Module may be used with the S6000FE, S6000PE, or LR100 series Electric Latch Retraction (ELR) device 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.

- The two sequencer channels may be operated as two independent doors or in tandem mode for pairs of doors.
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.
When the EMC is used in the tandem mode, power supply requirements for a pair of doors are minimized.
Since the attached electric latch retraction devices are powered in a sequential manner, the inrush current of each device is staggered. This creates a lower current requirement upon activation. A smaller power supply can now be used to operate the pair of devices.
