Abstract
A detection unit comprises a support element and at least one module connectable to the support element, each module comprising a housing and an infrared detector fitted therein. When connected each module has a defined circumferential position relative to the support element. Preferably, the detection unit is designed for fitting three modules which circumferentially enclose the support element, as well as a further module.
Claims14
A detection unit comprising:
- a support element;
- means for fixing said support element on a wall or ceiling of a space to be monitored;
- a preselected number of detector modules, each module including a housing and at least one infrared detector fitted therein;
- means for releasably connecting a plurality of such detector modules to said support element in a plane parallel to and around said support element;
- wherein said connected modules circumferentially enclose said support element and each connected module has a defined position and detection field relative to said support element and wherein a detection field pattern desired for the space to be monitored is achieved by said preselected number of detector modules.
