PIR Occupancy Switch Ceiling Switch - 10 Amps
Detection zone: 360°
PIR occupancy switch has a passive infra-red quad person detector.
This detects the movement of a warm body, moving within its detection zone.
When such a movement is detected the load is switched on.
There is an adjustable time lag function,
The time lag is the time that must elapse with no movement detected
before the PIR occupancy switch will switch off.
There is a built-in adjustable photocell override,
which can be used to keep lights off when there is sufficient daylight available.
The photocell can be set to inactive when controlling heating, ventilation or air conditioning.
