ABSTRACT:
A fire or smoke detection and alarm system (10) that is enclosed in an elongated enclosure (36) and installed alongside an exit door (52). The enclosure (36) includes a first circuit (12) having integral smoke and fire detectors (14a), (16a) and a redundant second circuit (20) having an integral sound activated switching circuit (22) that is energized by a pre-existing remote audio alarm (24a). The two circuits (12), (20) may be selected either manually by a toggle switch (28) or automatically by an automatic switching circuit (30). When either of the two circuits are energized by smoke or fire, a stroboscopic flashing lamp (34a) and an audio alarm (34b) that are located near the bottom of the enclosure (36), are turned-on. When a fire occurs and smoke fills a room or corridor, panic and disorientation are common. By having the lamp (34a) and audio alarm (34b) near the floor, a person can crouch and be guided by the beam of the light and sound toward the exit door and out to ultimate safety.
