What is the audible alarm output of the PASS device at 10 feet?

The audible alarm output of a PASS (Personal Alert Safety System) device is designed to be clearly heard in challenging environments, such as those encountered during firefighting. At a distance of 10 feet, the output of a typical PASS device is generally around 98 decibels or more. This high level is necessary to ensure that the alarm can be heard above the ambient noise levels often present in a fire situation, which can include equipment noise, multiple voices, and the roar of flames.

The specification of 98+ decibels indicates that the alarm is loud enough to alert nearby firefighters and potentially those in immediate danger, contributing to their safety by ensuring they can respond promptly to an emergency situation. The design intent is to maximize the effectiveness of the device in various conditions, thus the determination of this specific output is essential for user safety.
