Abstract
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.
