Wall PIR Occupancy Switch
Detection zone: 120°
Wall Mounted PIR Switch
Direct replacements for existing wall switches.
No neutral wire is needed.
Hence they are very quick and inexpensive to install.
It fits into a plaster depth (16mm) wall box.
Has a manual override off switch on the front of the plate.
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.
Time lag range:
10 seconds to 40 minutes in 9 steps.
- Photocell range:
100 to 1000 lux, and inactive.
- Max Load:
1500W (6 amps) of any type of load (including fluorescent lights and fans)
- Minimum load is 40W resistive or 100W inductive,
or for wiring in parallel 50W resistive or 120W inductive per WAPIR in the circuit.
- Walk test
The WAPIR requires a permanent live supply, and should only be used in applications where the lights would not be on for more than 12 hours per day.
This is to allow its rechargeable battery enough time to recharge itself from the mains supply.
- Detection zone: 120°
- Surface or Flush Mounted
