Overview

The Signal Relay controller is a versatile device that can be used in a large number of applications including process control, HVAC and hospitality applications. The signal relay controller activates the output with receive input from a linked sensor or switch transmitting:

• ambient light levels monitored by an wireless photo sensor
• occupancy state monitored by a wireless occupancy sensor
• switch action from a wireless single or dual paddle wall switch
• switch action from a wireless key card switch
• switch action from a wireless door/window (reed) switch
• gateway control implementing schedules or other events

The signal relay can be used in distributed process applications to eliminate troublesome wiring runs using linked wireless electrical switches. A low voltage or line voltage event can be transmitted to the signal controller triggering the dry-contact relay connected to any PLC or controller input.

The controller fits equally as well into hospitality applications. Responding to linked key card switches that monitor suite occupancy/vacancy, the controller can also be used to enable and disable air-conditioning equipment based on the occupancy state and/or patio door position.

Other features include telegram repeating and BEMS system integration allowing the controller to be used both in distributed control applications or as a component of a centralized system.

The controller is Range Confirmation® compatible, working with all Echoflex sensors equipped with the Range Confirmation® feature to provide visual feedback of a linked sensors signal strength for optimal sensor placement.

Echoflex offers pre-linking and pre-commissioning on all products sold as a system through Echoflex. In addition to this service, Echoflex provides several methods of configuring and verifying controller operation once installed on-site:

1. Use the linked sensors and Simple Tap™ to make quick changes to individual controllers.
2. Use Smart Click® to access more configuration parameters using a linked switch.
3. To access the full menu of configuration parameters, Echoflex’s Garibaldi software is a PC based tool that includes hands-free commissioning.
