Which feature is NOT located in the Sensor Module?

• A. It houses batteries for PASS and HUD
• B. It contains two omnidirectional speakers
• C. It detects motion to trigger auto-engagement
• D. It includes a built in display that shows cylinder pressure

Answer: (D)

The Sensor Module handles sensing and signaling functions for the SCBA. It processes sensor data, controls auto-engagement (based on motion or inactivity), and powers the electronic alarms and related components such as the HUD and PASS system. The audible alerts and the power for those functions are typically managed here, including any small speakers needed to emit alarms. The cylinder pressure reading, however, is presented on the Heads-Up Display mounted on the firefighter’s mask. The HUD continuously displays cylinder pressure by receiving data from the system, so the wearer can read it at a glance without looking away from the work area. So the feature not located in the Sensor Module is the built-in display that shows cylinder pressure; that reading belongs to the Heads-Up Display on the mask.
