Infra-red occupancy switch April 1st 2007 Danlers has issued a revised version of its ceilingmounted, directional passive, infra-red occupancy switch. The new switch can be rotated and lowered to detect the movement of people in the vicinity. It then switches the lighting, or other load, on and off as necessary. The switch also features a built-in adjustable photocell, so that, if required, lighting can be kept off while there is enough daylight available. More articles from Danlers Limited: |
