What is the role of detectors in SHS design?

• A. Detectors never initiate release
• B. Detectors initiate release or monitor condition and integrate with control system
• C. Detectors only log events after discharge
• D. Detectors only warn after fire

Answer: (B)

Detectors in SHS design are central to sensing fire conditions and guiding the system’s response. They aren’t just warning devices; they can act as initiating devices that directly trigger agent release, or they can feed real-time condition data into the control system so the system can decide when and how to release. This integration ensures a coordinated, timely response and allows the control panel to manage alarms, interlocks, and discharge logic while monitoring for faults or abnormal conditions. By linking detection with the control system, SHS can avoid false discharges and still provide prompt protection when a fire is detected.
