Concerning the illustrated fire detection and alarm system, what statement is true concerning the wiring between zones? Illustration EL-0114

Correct Answer: Option B — The zones are all connected in series by means of the fire locating switches and the ground locating switches.

Fire detection and alarm circuits utilize loop architectures where fire locating and ground locating switches systematically configure zone continuity. Under IEEE 45 standards, multi-zone monitoring panels rely on series-interconnected configurations through these specific diagnostic switches to isolate faults and verify continuous loop integrity across monitored vessel compartments.
