KEY FEATURES

The PIR sensor has been designed to switch lighting, heating and ventilation
loads up to 10A. The unit is switched on by the detection of moving infra red

The Occupancy Detector sensor has been designed to switch
lighting, heating and ventilation loads up to 10A. The unit is
switched on by the detection of moving infra red heat within a
specified range. When infra red heat, such as a moving body,
is no longer detected, the unit will switch off the load after the
adjustable time period has elapsed. If infra red heat is detected
again during the timing period, the timing sequence will restart.
The unit has a lux level adjustment and Auto Lux function, which
measures the ambient light levels and prevents lighting being
switched on, when there is sufficient lighting in the room. There
is a sensitivity adjustment and test mode function added for your
