• A. Sometimes
• B. True
• C. False
• D. Not applicable

Answer: (B)

Heat detectors in basic wet chemical fire suppression systems are designed to respond to heat quickly and reliably in a damp, kitchen environment. Fusible-link heat detectors are the traditional choice because they are self-contained and don’t rely on external power or electronics, melting at a predetermined temperature to trigger the system. This makes them robust against electrical issues and moisture exposure. Electronic heat detectors that do not use fusible links can also be used, but only when the system is designed and listed for that type of detector. They rely on sensors and electrical signaling to actuate the suppression system, which means they require proper power, wiring, and maintenance to avoid false alarms or failures. When appropriately approved, they provide an alternative detection method. So the statement is true: heat detectors for basic wet chemical systems are usually fusible-link, although electronic heat detectors that do not use fusible links can also be used.
