Duress Alarm | 挟持警报

A system that reports the presence of one or more persons trying to force an individual to enter, or reenter, a facility against the individual's will. Although the triggering devices for hold-up, duress, and panic alarms are often the same or similar, police response may differ. A duress alarm, for example, may be designed to detect and silently report an employee being forced back into a protected facility to provide access to a safe, vault, drug storage area, or area containing confidential records. The intent is generally not to make the criminal aware that a call for help is being triggered to the monitoring facility. In a residential environment, a duress alarm could signal an abduction or rape attempt.

A duress alarm can also be considered as a medical alarm/emergency.

指一种报告一个人或者多个人试图挟持个人违背其意愿进入或者再次进入设施的机制。尽管触发紧急，挟持报警的设备相同或者相似，但是警察应对措施会不一样。挟持警报，设计为检测并无声报告当员工被迫返回保护设施，并提供进入保险柜，金库，药物储存区域或者包含保密信息场所。目的通常是为了不让犯罪者意识到求救信号已经向监控中心发送。在住家环境中，挟持警报可能意味着诱拐或者强奸。

挟持报警也能被认作为医疗警报/紧急报警
