The System Sensor R-10E is a multi-voltage conventional relay in a steel enclosure. It provides a single Form-C (SPDT) contact set with a red activation LED. Fire alarm installers use it for high-current switching jobs. For example, fan and damper control, door control, and air handling unit shutdown are typical applications.
The enclosure has a removable front cover for easy access. In addition, an LED viewing hole on top shows relay status without opening the cover. The relay, terminal strip, mounting track, and hardware come pre-mounted inside.

Need two contact sets instead? Then specify the System Sensor R-20E, the DPDT version in the same enclosure. Alternatively, the R-10T offers the same SPDT relay in track-mount form without the enclosure.
