摘要： An alarm system has a controller which communicates over a conductive path with a remote module. An indicating device, such as an alarm bell, strobe light, audible horn or other device is coupled to the remote module and activated when a control signal is received from the controller. A rechargeable battery is provided in or adjacent the remote module, and acts as a reservoir for the power to energize the indicating device upon connection. The remote module receives charging current over the conductive path from the controller, and this current is very low, substantially less than the current level required to energize the bell, horn, or strobe. A constant power dc-to-dc converter is provided to charge the battery at the appropriate rate, while drawing a substantially lesser amount of power from the controller. Both the rechargeable battery and the indicating device are supervised, and any malfunction reported to the controller.
摘要翻译：报警系统具有通过导电路径与远程模块进行通信的控制器。诸如报警铃，闪光灯，听筒或其他设备的指示装置被耦合到远程模块，并且当从控制器接收到控制信号时被激活。在远程模块内或附近提供可再充电电池，并且充当用于在连接时为指示装置通电的电力的储存器。远程模块通过控制器的导电路径接收充电电流，该电流非常低，大大小于为铃，喇叭或频闪通电所需的电流水平。提供恒功率dc-dc转换器，以适当的速率对电池充电，同时从控制器中抽取相当少的功率。对可充电电池和指示装置进行监控，并向控制器报告任何故障。

摘要： A plurality of remotely located transponder units each communicate with a central station unit to provide a full array of alarm and status signals to the central station. The transponder units are capable of remotely addressing the central station unit directly, without the need for human intervention at the central station, to alter subscriber opening and closing times, passwords, and other system parameters. The transponder also permits defective zones to be shunted either from the central station or locally pending repair, testing and status checks.

摘要翻译：多个远程位置的应答器单元各自与中央站单元通信，以向中心站提供完整阵列的报警和状态信号。转发器单元能够直接远程地对中心站单元进行寻址，而不需要在中心站进行人为干预，改变用户的开启和关闭时间，密码和其他系统参数。应答器还允许从中心站或当地待命的修理，测试和状态检查来分流故障区域。
