How does a gas-detection alarm integrate with SHS?

• A. It provides automatic extinguishing without human input.
• B. It monitors ambient gas concentrations and triggers or modifies release/alarms if concentration is detected or if levels indicate compromised safety.
• C. It only sounds a general alarm during maintenance.
• D. It measures only the temperature.

Answer: (B)

Gas-detection alarms integrate with SHS by feeding real-time gas concentration data into the system’s control logic, so the SHS can respond appropriately. When the detected gas level reaches a defined threshold or indicates a safety compromise, the SHS can act by initiating or adjusting the release of extinguishing agents and by changing alarm states. This makes the system react to the actual hazard conditions rather than just running on a fixed sequence. The detectors aren’t inherently the extinguishing mechanism themselves, and they aren’t limited to maintenance-only signaling or to measuring temperature. They provide crucial input that governs whether and how the SHS should respond to a given gas hazard.
