What triggers the PASS device alarm?

What triggers the PASS device alarm?

• A. The PASS device emits an alarm when the firefighter stops moving.
• B. It alarms when the firefighter runs a distance.
• C. It alarms when air is low.
• D. It alarms when the radio is on.

Answer: (A)

The thing being tested is how a PASS device signals danger by monitoring motion. A PASS alarm goes off when the firefighter stops moving for a preset period, signaling that the wearer may be incapacitated or in distress and needs help. Movement resets the timer, so as long as you’re moving, the alarm won’t sounds. This safety feature is separate from other alerts like low air in the SCBA or radio status, which are not triggers for the PASS alarm. So the correct understanding is that the alarm is activated by a lack of movement, not by distance traveled, air level, or radio activity.
