Question 275Electricity/Electronics - QMED70% to pass
Concerning the illustrated fire detection and alarm system, what statement is true concerning the wiring between zones? Illustration EL-0114

AI Explanation
The correct answer is B) The zones are all connected in series by means of the fire locating switches and the ground locating switches.
This is the correct answer because in a typical fire detection and alarm system, the zones are connected in series through both the fire locating switches and the ground locating switches. This allows the system to detect fires and ground faults, which are crucial for safety and proper operation.
The other options are incorrect because A) only mentions the ground locating switches, C) describes a parallel connection, and D) only includes the fire locating switches, which does not accurately represent the wiring between the zones.
