Please see Extra Specification for Wall Mounted PIR Switch - No Neutral at the bottom of this page.


Standard PIRs are 230V, optional 24V PIRs are also available (if 24v please specify AC or DC).

PIR Quad Detector

Detects movement of a warm body moving within its detection zone.

Adjustable Time Lag

This is the time that must elapse with no movement detected before the PIR will switch off. Adjustable from 10 seconds to 40 minutes.

Adjustable Photocell

Used to keep lights off when there is sufficient natural light. Range: 100 to 1000 Lux. The photocell can only be used in this way if the amount of natural light exceeds the level of artificial light.

The photocell can be set to maximum when controlling H&V equipment.

Loading: All models can switch up to 6 amps (1500W at 230VAC) of resistive and fluorescent lighting loads or up to 3amps (750W) of electronic and wire wound transformer loads, or up to 2amps (500W) of CFL, 2D Lamps LED Drivers and LED Lamps and fittings or up to 1 amp (250W) of valve, fan or motor loads.

Several PIR sensors can be wired in parallel for larger spaces. For best coverage the PIR sensors should be spaced every 5 metres in either direction.

Easy to fit

Only 3 wire connections needed: Live, neutral & switched live.

Extra Specification for Wall Mounted PIR Switch - No Neutral

Fits into a plaster depth (16mm) wall box. Has a manual override off switch on the front of the plate. 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.

Minimum load 40W resistive or 100W inductive, or for wiring in parallel 50W resistive or 120W inductive per PIR/D/WM-NN in the circuit.
