ABSTRACT:
An alarm system provides both audible and visual signaling of emergency conditions. The audible signaling component of the system comprises a well-known audible fire alarm including an electric horn, bell or siren and an activating switch for applying enabling potential to operate the audible alarm in response to occurrence of particular emergency events. The visual signaling component of the system comprises a sensor for sensing the application of a current-voltage to the terminals of the audible device, at least one high intensity lamp of the type producing illumination of such intensity and duration so as to excite the human optic senses, a power supply and a trigger circuit. The trigger circuit is connected to the lamp, the power supply and the sensor and applies enabling potential to the lamp from the power supply in response to the receipt of a signal from the sensor.
