Usage
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 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
/ Test mode
being switched on, when there is sufficient
lighting in the room. There is sensitivity
adjustment and test mode function added
for your convenience.

across switch live and neutral supplies of
