What sprinkler alarm system is F circuit?

What sprinkler alarm system is F circuit?

• A. Sprinkler alarm
• B. Flooding alarm
• C. High temperature alarm
• D. Fire alarm

Answer: (C)

In sprinkler systems, different circuits carry signals from different types of detectors so alarms are clear and fast. The F circuit is dedicated to the high temperature alarm—the heat detectors placed around sprinkler zones monitor ambient temperature and will trigger this circuit when a preset temperature is reached, signaling a potential fire even if sprinkler heads haven’t released water yet. This separation from water-flow (sprinkler) signals, flooding (leaks) signals, and general fire alarms helps ensure a heat-induced warning is delivered promptly and accurately. So the F circuit corresponds to the high temperature alarm.
