ZONE : An INPUT circuit that when faulted will trigger a programmed response in the CONTROL PANEL. ZONES typically denote areas of the building (or premises) and may also identify specific device types (pull stations, smoke detectors, heat detectors, etc.). These days, ADDRESSABLE PANELS utilize software zones (ones actually programmed to illuminate a specific indicator lamp) as opposed to the older style conventional panels in which the zones are "hardwired".
