    icn-detection-strongStrong detection zone
    ie. person moving arm

    icn-detection-secondarySecondary detection zone
    ie. person walking (less sensitive when walking straight towards PIR switch)

    PIR Quad detector gives 124 detection areas within the zone

    In open plan areas

    For best coverage the CELO should be spaced every 5m in either direction
