This Danlers ceiling flush passive infra-red occupancy switch (PIR) can be flush mounted into suspended and plasterboard ceilings. It includes a 2 metre connecting flex to make installation quicker and easier.
These PIR switches incorporate a passive infra-red quad sensor to detect movement of a warm body within their detection zone and a photocell to monitor the ambient light level.
Upon detecting movement, if the ambient light is dark enough, the PIR switch will turn the load on. The ambient threshold can be set by the user to between approximately 100 lux and infinite lux (photocell inactive) via the LUX adjuster.
If no more movement is detected within a pre-selected time, then the PIR switch will turn the load off. This time lag can be set via the TIME adjuster to 10 seconds, 20s, 40s, 1 minute 15 seconds, 2m30s, 5m, 10m, 20m or 40 minutes.
