CA 2196014

A dual element PIR detector for a security system uses a series of beams in selected areas to limit the amount of radiation received from small domestic pets. A series of alternating beams define dead zones and the beams and dead zones provide size discrimination where a small domestic cat or other small pet does not have sufficient size to cause IR responses in two sensors sufficient to cause an alarm condition.

Détecteur de mouvement passif à infrarouge à deux éléments pour système de sécurité, utilisant une série de faisceaux dans des zones choisies afin de limiter la quantité de rayonnement provenant de petits animaux domestiques. Une série de faisceaux alternants? définissent des zones mortes. Celles-ci et les faisceaux assurent une discrimination de taille de sorte que de petits animaux domestiques, comme des chats, n'ont pas une taille suffisante pour provoquer dans deux détecteurs une réponse infrarouge qui déclencherait une alarme.
