Long life detector

A long life, surface mountable ambient condition detector (10) includes a non-replaceable battery (38) for the purpose of providing power to the detector. The detector includes an activation switch mechanism (14a) having a one-time, or single use turn-on characteristic. The activation switch mechani...

Beschreibung
Zusammenfassung:	A long life, surface mountable ambient condition detector (10) includes a non-replaceable battery (38) for the purpose of providing power to the detector. The detector includes an activation switch mechanism (14a) having a one-time, or single use turn-on characteristic. The activation switch mechanism (14a) switches the battery (38) once from a non-conducting state to a state of electrical conduction with a control unit (32) of the detector. The switch mechanism may include a frangible member (12a, 12b) for switching the battery (38) from the non-conducting state to the electrical conducting state. Until the detector (10) has been energized, the frangible member (12a, 12b) blocks mounting of the detector on the surface.
