Ceiling surface mounted PIR Occupancy switch with Short visit function and Courtesy exit mode

This PIR occupancy switch is designed for the automatic control of lighting loads with the additional benefit of manual temporary intervention when used in combination with retractive wall switch (momentary).

These surface-mounted models are ideal for solid ceilings.

The CESR PIRSV is a hard wired version and can be mounted directly onto solid ceilings or onto a range of different mounting boxes.
