Technical Specifications

Voltage
Standard PIRs are 230V, optional 24V PIRs are also available.

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 inactive when controlling H&V equipment.

Loading
Will switch up to 6amps (1500W) of resistive, fluorescent or inductive lighting loads, or up to 1amp (250W) of fans.

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.
