Up to 127 line devices (detectors, call points, sounders or interface units) may be connected to each of the ZP3 loops.
All loop devices incorporate switch settings enabling them to be assigned a unique address, the location of which is pinpointed and polled by the panel every two seconds.
Variations in the detector's environment caused by increases of temperature or products of combustion are reported to the panel where they are processed and compared to known fire data prior to any alarm output being activated.
