How Personal Alarm Devices Work

A personal alarm device is a wearable device that allows people to call for help in the event of an emergency. They usually feature an SOS button and may also include fall detectors, GPS monitoring, and two-way communication.

A personal alarm is a wearable device that creates a loud siren when pressed. The siren is designed to scare off potential attackers and disorientate them, thus deterring them from taking action.
