System Sensor R-20T Single 2 Form-c Relay with Actuator Led

Product Description

The SYSTEM SENSOR R-20T is a single 2 Form-C relay module designed for use in fire alarm and life safety control systems. It provides two independent Form-C relay contacts in a single unit and incorporates an actuator LED that gives a clear visual indication of relay status during system operation and testing. The R-20T is installed by licensed fire alarm technicians and system integrators as part of a larger fire alarm control panel network, where reliable relay switching is critical to proper system response.

The R-20T is suited for commercial and light industrial fire alarm installations where controlled switching of auxiliary loads is required. Typical applications include HVAC shutdown, door holder release, elevator recall, and other ancillary control functions triggered by a fire alarm event. The module fits into structured fire alarm system architectures that call for addressable or conventional relay outputs.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. De-energize the fire alarm control panel and follow lockout-tagout procedures before wiring or mounting the relay module. Verify load ratings of connected devices do not exceed the relay contact specifications before commissioning. After installation, perform a full functional test to confirm relay operation and LED indication.
