Apparatus and method for providing alarm syncrhonization among multiple alarm devices |
摘要 |
A method and apparatus for synchronizing a series of interconnected alarm devices. The alarm device detecting an alarm condition produces a signal having a distinct rising edge which is detected at each of the remaining alarm devices. A pulsed alarm signal having a fixed number of pulses is generated at each of said remaining devices in response to the rising edge. A reset signal from the alarm device detecting the alarm condition resets each of the remaining alarm devices after each fixed number of pulses is produced so that each of said devices has a pulsed alarm signal which begins and ends at substantially the same time.
