What is the maximum duration a PASS device can emit a full alarm at 95-100 decibels?

The maximum duration for which a Personal Alert Safety System (PASS) device can emit a full alarm at a sound level of 95-100 decibels is indeed 10 hours. This duration is established to ensure that firefighters have an audible warning signal that can last for an extended period of time, providing a crucial safety alert in emergency situations where a firefighter may become incapacitated or trapped.

The 10-hour runtime is designed to balance battery longevity with the necessity of maintaining an effective alert system. This duration allows for sufficient time to facilitate rescue operations while also ensuring the device doesn't drain its battery too quickly, which could compromise safety. Other time durations, while potentially relevant in different contexts, do not meet the operational requirements and safety standards established for PASS devices.
