  • Life safety system with energy saving visual alarm appliance and method
    Patent number: 6417772
    Abstract: A life safety system with a micro-controller that is programmed to operate both a visual signal and an audible signal. One feature of the system is that a user is permitted to enter a temporal signaling mode for not only the audible signal, but also the visual signal. The program includes an energy saving routine that operates the visual signal in the temporal mode with an energy consumption that is substantially smaller than required for operation in a continuous mode. The temporal pattern has four cycles with one flash pulse per cycle for the first three cycles and no flash pulse for the fourth cycle.
