    • In a security system having a remote monitoring station, a sensor is tested when the security system is in a normal operating mode. The sensor is tested by actuation of a button on the sensor. Actuation of the button generates a signal indicating that a test has been conducted. Upon the generatation of both an alarm signal generated by the test and a signal indicating that a test has been conducted, the security system determines that the alarm signal was generated by a test of the sensor and not by the detection of alarm conditions by the sensor.
    • 在具有远程监视站的安全系统中,当安全系统处于正常操作模式时,测试传感器。 传感器通过致动传感器上的按钮进行测试。 按钮的启动产生一个指示已经进行了测试的信号。 在通过测试产生的报警信号和表示进行了测试的信号的生成时,安全系统确定报警信号是通过传感器的测试产生的,而不是由传感器检测报警条件 。
