The System Sensor R-20T is a multi-voltage control relay with a single DPDT contact set. It includes a red activation LED, terminal strip connections, and a mounting track. As a result, it provides reliable switching for fire alarm and control circuits.
Installers use the relay to interface fire alarm panels with auxiliary equipment. For example, it can support HVAC shutdown, door release, and other control functions. The terminal strip also simplifies field wiring.
System Sensor R-20T Voltage Range
The R-20T accepts a wide operating voltage range. Specifically, it supports 18-35 VDC, 18-35 VAC, 115 VAC, and 230 VAC. Therefore, one model fits many system architectures.
The DPDT configuration provides two independent sets of switching contacts. In addition, the red LED confirms when the relay is activated. The included track and hardware also speed mounting.
