Integrated fire exit alert system |
摘要 |
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.
