Ceiling surface-mounted PIR absence switch

cesfa-pirar

Ceiling surface-mounted PIR absence switch – additional range version.

When someone enters a room the lights are turned on using a wall switch. When the occupant leaves the room or area of detection the CESFA PIRAR automatically switches the lights off after a pre-selected time.

The override OFF function allows the occupant to turn the lights off from the wall switch (while the CESFA PIRAR is in the ON state) without waiting for the pre-selected time lag to time out. The lights can be switched back ON by operating the wall switch in the usual way.

Product code: CESFA PIRAR

 

 

Ideal for meeting rooms, bedrooms, hotel rooms, student and military accommodation, classrooms etc.

Can be mounted on a square pattress box, order code: PABO.
