The Wall Mounted PIR occupancy switch provides presence or absence occupancy-based switching for lighting, heating, air conditioning and ventilation equipment. The built-in PIR (passive infra-red) sensor detects motion of body heat, providing convenient activation of the connected load whilst saving energy by switching it off automatically when the space becomes unoccupied (after an adjustable period). An adjustable ambient light threshold optionally inhibits initial activation when the area is adequately lit, reducing wasteful use of lighting.

The WMPAD3-L includes a touch-sensitive override button and offers the flexibility of two operating modes to suit either manual or automatic initial activation.  This makes it ideal for use in meeting rooms where lighting needs to be turned off during presentations.

The WMPAD3-L provides an illuminated button to aid location of the unit in the dark (when used in Absence Mode). The LED also acts to facilitate accurate setup of the light sensor function.
