Integrated fire exit alert system
First Claim
1. A fire exit alert system comprising:
- fire exit door hardware having a case;
a control circuit mounted in the fire exit door hardware case, the control circuit including;
a storage element for storing a voice signal, the voice signal indicating in words that the source of the voice signal is an exit;
a trigger input adapted for receiving a fire detection signal from a fire detection system;
a speaker output; and
a light source output;
a speaker connected to the speaker output of the control circuit for broadcasting an audibly locatable signal, comprising at least the voice signal, to indicate that the source of the voice signal is an exit; and
a light source connected to the light source output for providing a visually locatable indication of the location of the fire exit alert system;
the control circuit turning on the light source, retrieving the voice signal from the storage element and repeatedly sending the voice signal to the speaker output upon receipt of the fire detection signal.

Abstract
A fire exit alert system, preferably integrated into an exit device or automatic fire exit door closer, uses sound and light to signal the location of a fire exit in darkness and smoke-obscured rooms. The alert system includes a voice signal, such as “EXIT LOCATED HERE,” to signal that the location of the voice is also the location of the exit. A white noise signal generator is used to supplement the voice signal and produces a sound that is particularly localizable by the human ear. A strobe light and a laser are used to produce a visual guide to the location of the exit. The strobe light is flashed when the word “HERE” is used in the voice signal. The laser is used to produce a cone of light that points towards the fire exit alert system.
