What is the primary purpose of the duress alarm feature?

The primary purpose of the duress alarm feature is to send a silent alarm when an individual is in a situation where they are being forced to disarm the alarm system against their will. This feature is critical for personal safety, as it allows a user to alert authorities discreetly without alerting the intruder that help is being summoned. In situations where a homeowner may be threatened, the ability to activate a silent alarm can be a lifesaving measure, enabling law enforcement to respond without drawing the attention of the assailant.

Other options, such as emitting a loud noise or illuminating the premises, serve different purposes within a security system but do not specifically address the scenario of duress. Notifying authorities in real-time is also important; however, the unique function of the duress alarm is its discreet nature, which allows for help to be requested without escalation of the situation.
