Abstract

A flashing alarm device responsive to audible signals produced by a smoke detector when the smoke detector senses a smoke condition, the alarm device including a circuit with a microphone portion for responding to audible signals produced by the smoke detector and an amplifier circuit portion for amplifying signals produced by the microphone, a switch circuit portion having a control input connected to the output of the amplifier circuit portion, and another circuit portion including a battery, a timer circuit, and a light bulb, the battery having a connection to the amplifier circuit and to the timer circuit, the timer circuit and the light bulb being connected in series with the switch circuit portion for energizing and de-engergizing the light bulb whenever the switch circuit portion is in its conducting condition. The device may also include a housing for the components and the device may optionally be constructed to operate on transmitted and received radio frequency signals.
