摘要
介绍一种利用数字电路对主叫用户电话进行信号识别和智能化控制、实现多地点语音（或其它信息）报警的应用电路，即自动报警电话。本报警电话以入侵探测器、烟雾探测器或其它安全防范探测器为前端检测装置，以用户电话线为传输通道，当检测装置发出报警触发信号时，自动报警电话模拟人工呼叫程序将报警语音发送到预定的各被叫用户，完成被监控区域特殊情况下的自动报警。
A kind of automatic alarm phone which can identify the caller's signal and realize
multi point voice (or Other)alarm with digital circuits is described. With the intrusion
detectors,fume detectors and any other safety detectors as pre end detectors and the caller's
line as transmission channel, the automatic alarm phone will simulate human dialing procedure
and send voice alarm to the pre set called parties while the detectors send the alarm signals to
the caller's phone. The automatic alarm of the monitored area is done as such.
