The ceiling mount, low profile panoramic DS936 PIR Detector uses alternate polarity pulse count. It also
uses a pointable Fresnel lens to provide up to 7.5 m (24 ft) of coverage and can be mounted on the surface, or semi-flush directly to a ceiling or a standard octagonal electrical box.
Mounting
The detector should be mounted at a height range 2 m to 3.6 m (7 ft to 12 ft) either surface mounted or semi-flush on ceiling.
