How long does the PASS device wait before emitting an alert after receiving a signal?

The PASS (Personal Alert Safety System) device is an essential safety tool used by firefighters. It is designed to alert others if a firefighter becomes immobilized or unconscious. Upon activation, the device generally has a delay period of 30 seconds, which can be adjusted based on specific operational protocols. However, when the PASS device receives no movement or signals from the user, it typically waits for 20 seconds before beginning the alert process.

The rationale behind this wait time is to prevent false alarms. Firefighters often move about quickly while performing tasks, and a shorter delay might result in unnecessary alerts, potentially diverting attention from genuine emergencies. Therefore, the correct interval before the PASS device emits an alert is 20 seconds, allowing for a reasonable time frame for movement and activity while still ensuring safety protocols are in place.
