A Zone in Fire Alarm Systems refers to an area or section of a building that shares the same fire detection and alarm characteristics. Each zone has its own set of smoke detectors, heat detectors, pull stations, and other fire-related equipment.nnA Loop/Fire Alarm System is a network configuration where devices such as sensors, control panels, and annunciators are interconnected to create a continuous circuit. This allows for the transmission of alarm signals throughout the system. In case of a break or fault in one part of the loop, the system can still operate through alternative paths.
