How long can a PASS device in full alarm last before it needs to be reset or motion detected?

A PASS (Personal Alert Safety System) device is designed to enhance firefighter safety by providing an audible alarm when a firefighter is motionless for a certain period. In full alarm mode, which activates when a firefighter has not moved, the device can continuously sound for an extended duration.

The correct response indicates that a PASS device can sustain its full alarm state for up to 10 hours before it requires a reset or a motion signal to deactivate. This time frame offers a sufficient window for rescuers to locate a downed firefighter, making it a critical feature in emergency situations. Understanding the operational limitations of a PASS device is crucial for effective safety measures and ensuring that all personnel are aware of how long they remain in a monitoring state.

In contrast, the other durations provided by the incorrect options exceed the realistic operational capabilities of typical PASS devices. These limitations are designed not only to manage power consumption but also to ensure the device is effective during emergencies without being overly reliant on a prolonged alarm state.
