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.
