Ceiling PIR Switch

The unit is a self contained, ceiling mounted, Passive Infra Red Detector and switch. It is mains powered and produces a switched mains output. This is a relay switch which can be connected in parallel to other switches. Adjustments can be made to on-time and lux level. The unit can be installed without the need to access both sides of the ceiling.

A self contained ceiling mounted passive infra red detector with a switching capacity of 16A.

The PIR sensor pickup will detect all round 360° movement at a distance up to 6 metres within an even 120° arc about the right angle centre line of the ceiling mounted unit.

A novel installation method protects the ceiling and allows adjustments to be made more accurately without the unit hanging on its cable.

Access from below the ceiling only is required for fixing.

Variable 'on' time from 18 seconds to 18 minutes (the timer will reset after each time the sensor is triggered) and lux levels from full daylight to full dark.

There are several versions, 2m and 4m of cable length and with or without IP44 (splashproof) rating. All these are also available as a surface mounted version when there is no ceiling void.
