Silent Alarm | 无声报警

For this type of alarm there is no audible indication that the security system is in alarm condition howver, the alarm panel would signal through to an ARC. This would typically be used when the intention is to not alert the intruders that they have been detected, but notify the authorities.

这类警报没有声音指示表明安防系统处于报警状态，但是报警主机会向接警中心发出信号。意图是在不让入侵者发现的情况下通知当局。
