Security Door Controls

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. 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.

Features:

• Dual channel sequencing
• Sequence operators and latch retraction
• Delayed dry auxiliary output
• Field selectable normally open (NO) or normally closed (NC) outputs
• Auto-sensing dual voltage
• Visual status indicators (LED)

Models:

• EMC: Dual channel exit device sequencer

Applications:

• The two sequencer channels may be operated as two independent doors or in tandem mode for pairs of doors.
• Electrified panic device and operator sequencing for single or pair of doors
• Tandem: When EMC is used in tandem mode, power supply requirements for 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 a pair of devices.
