Which device is designed to help locate a wearer in distress by emitting an audible alarm?

Explanation:
The device that is designed to help locate a wearer in distress by emitting an audible alarm is the Personal Alert Safety System. Worn on the SCBA, it automatically sounds a loud alert if the wearer stops moving for a preset period or if the wearer manually activates it. This audible signal helps teammates quickly locate and reach the distressed firefighter in smoky or low-visibility conditions. The regulator, purge valve, and facepiece, by contrast, are part of the breathing air system and do not provide a distress alarm.
