Abstract
A warning device (10), typically situated in an illuminated exit warning sign, broadcasts voice commands generated by a synthetic speech synthesizer (U3) via speaker (SP1). A programmable microcomputer (U2) senses a loss of AC power and generates a user initiated voice command. Upon the detection of a fire or smoke condition, the microcomputer (U2) generates a priority warning. The device (10) includes a self-contained, charged power supply (12) that powers the microcomputer (U2) and the synthesizer (U3) in the event that the externally supplied AC power ceases. Constant illumination is provided by lamps (32) or (40). A user operated switch aids in programming the microcomputer to provide two sets of audible phrases.
