Intelligent short-circuit isolator base for analog detectors of the ZP700 / ZX800 series. It detects short-circuits in elements and in the analogue loop for fire detection. Also supervises the partial deterioration of the wiring. It is recommended to install one unit every 20/30 elements (mandatory to install one insulator for every 32 elements according to Standard EN54-14), taking into account that the maximum number of insulators in a loop is 16. It does not include a sensor.
