Abstract
Abstract A passive infra-red sensor comprising a housing including a mounting base and a lens mounting cover element, detector support apparatus selectably positionable with respect to said mounting base along a first axis, an infra-red detector and a beam locator illuminator mounted on the detector support apparatus, a multi-faceted focusing lens including a first array of beam defining lenses arranged for optical coupling to the infra-red detector and a second array of beam defining lenses arranged for optical coupling to the beam locator illuminator.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
77 words
A passive infra-red sensor comprising: a housing including a mounting base and a lens mounting cover element; detector support means; an infrared detector mounted on the detector support means; and a lens arranged for optical coupling to the infrared detector; and lens mounting and locking retaining means arranged for snap fit engagement with said cover element, and which once inserted, can be removed only from the inside of the cover element and not from the outside thereof.
Claim 2
Dependent Claim
77 words
A passive infra-red sensor comprising: a housing including a mounting base and a lens mounting cover element; detector support means; an infrared detector mounted on the detector support means; and a lens arranged for optical coupling to the infrared detector; and lens mounting and locking retaining means arranged for snap fit engagement with said cover element, and which once inserted, can be removed only from the inside of the cover element and not from the outside thereof.
Claim 3
Dependent Claim
29 words
A passive infra-red detector according to claim 1 and wherein said lens is one of a plurality of interchangeable lenses having differing configurations corresponding to differing protection zone configurations.
