摘要： The invention proposes a method for localizing a ground fault of a fire protection system and also a fire alarm and/or extinguishing control panel comprising a plurality of connection points, a central unit and a ground fault identification module, wherein one or more subscribers can be connected to each connection point via a connection line. The method comprises, during or after identification of a ground fault by the ground fault identification module, the following steps: disconnecting the connection lines of one, more or all of the connection points by opening switching elements until at least no ground fault is identified by the ground fault identification module, and then connecting the connection lines successively for each connection point by closing the respective switching element.

摘要： A preaction dry pipe alarm valve (1) is provided for a sprinkler pipework (24) and sprinklers with a fire detection and extinguishing control panel (26). A water supply (38 and an air feed (37) are selectively in communication with the sprinkler pipework. A pilot control chamber (19) of the preaction dry pipe alarm valve (1) is depressurized in case of a fault message from the fire detection and extinguishing control panel (26). When the pilot control chamber (19) is depressurized and, in the case of a decreasing pressure in the sprinkler pipework (24), a quick opener (40) opens the valve head (2) of the preaction dry pipe alarm valve (1), so that extinguishing water can flow into the dry pipework (24). The system allows very short flooding times for the sprinkler pipework with no additional rapid vents installed in the pipework.
