ABSTRACT:
The smoke detector of the present invention is designed to warn hearing impaired persons of fire or smoke. A small, attractive, and inexpensive wall or ceiling mounted unit houses a dual chamber ionization detector, piezoelectric alarm horn, and a high intensity xenon strobe unit producing approximately 130 candela. In one embodiment, it is powered only from standard 120 volt AC power, although an internal battery standby version and low voltage D.C. version are alternative embodiments. The unit is furnished with a surface mount housing. It can easily be moved from room to room as required and it is intended to be easily hung on the wall about a foot from the ceiling.
