The System Sensor R-20E is a multi-voltage conventional relay with a single 2 Form-C (DPDT) contact set. It comes mounted in a steel enclosure with a red activation LED. Installers use it to switch high-current loads from a fire alarm system. Typical jobs include fan and damper control, door holders, and air handling unit shutdown.
The enclosure features a removable front cover for quick access. Also, an LED viewing hole on top shows relay status at a glance. Terminal strip connections, mounting track, and hardware are included.
