  • Tuning algorithm for clock source frequency drift
    Patent number: 7667577
    Abstract: An emergency evacuation and fire safety system has a plurality of signal devices. The clock source frequencies are tuned using the method and system such that the signals flash in synchronization continuously at a preset flashing interval upon detecting an alarm condition. A synchronization signal including a calibrated time position is broadcast at each predetermined time interval to all notification appliances. A time difference is computed between a local time position and the received calibrated time position by each of the notification appliances at each predetermined time interval and tuning the flashing of each of the one or more notification appliances by adjusting the preset flashing interval based on the computed time difference by each of the one or more associated notification appliances.
