Mini-module monitor Series To of 1 conventional zone. It allows the connection of up to 30 conventional detectors occupying an alone direction in the bow. Also it is used for the barrier connection (linear detector) to the analogical system. It can be fed from the own analogical bow providing that the number of conventional detectors is not superior to 15 or that the number of modules connected to the same bow does not exceed 8, without counting consumptions of other elements. It allows to supervise the wired up one of the conventional zone (short circuits and opened circuits) with indication in the module and in the analogical head office. Using the bases Z6-BS5 it allows to supervise detectors extracted while the rest of detectors of the zone continue working. For assembly in rail CASH.
