The PASS device includes which feature?

• A. It relies on battery from the HUD only
• B. It uses a wired connection to the main control unit
• C. It includes 2 omnidirectional speakers for PASS
• D. It requires external power supply

Answer: (C)

Audibility of the PASS alarm in all directions is achieved by two omnidirectional speakers built into the device, ensuring the alert can be heard from any angle in smoky or noisy conditions. This setup helps teammates locate a wearer quickly when visibility is limited. The PASS unit is self-contained with its own power source, so it does not rely on the HUD battery or require an external power supply, and it does not use a wired connection to the main SCBA control unit. In short, the two omnidirectional speakers are the feature that guarantees reliable audible alert regardless of orientation or obstacles.
