Strong detection zone
ie. person moving arm
Secondary detection zone
ie. person walking (less sensitive when walking straight towards PIR switch)For optimum coverage recommended mounting height between 2.4 and 5m.
PIR Quad detector gives 124 detection areas within the zone
Perspective view of detection zone
For optimum coverage recommended mounting height between 2.4 and 5m
Several PIR occupancy switches
In open plan areas
For best coverage the PIR occupancy switches should be spaced every 5m in either direction
