    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: The present invention relates to a housing for a fire alarm and/or extinguishing control station having a housing body (20), which comprises an opening (22) on a front side (24), a housing door (30) for closing the opening (22) and a hinge arrangement (40), which is configured to allow opening and closing of the housing door (30). The housing door (30) has an outer face (32), which faces an observer when the housing body (20) is closed and an inner face (34) which is opposite the outer face (32), wherein the housing door (30) has an indicator and/or operating component (36) on the outer face (32). The hinge arrangement (40) has a first axis of rotation (41) and parallel thereto a second axis of rotation (42) and is designed such that the first and the second axes of rotation (42) can be rotated in opposing directions when the housing door (30) is opened such that the outer face (32) of the housing door (30) and an interior (12) of the housing (10) are simultaneously facing the observer when the housing (10) is in the open state.

    摘要: The invention relates to an unmanned vehicle (2) for initiating a fire extinguishing action, comprising a vehicle sensor unit (6) for detecting a fire parameter KF of a vehicle monitoring region (8), a signal receiving unit (10) for receiving an instruction signal SI representing a reference fire status ZR for a fire detector monitoring region (12) of a stationary fire detector (14) and a target location (16), and a navigation control unit (18) for navigating the vehicle (2) to the target location (16) based on the instruction signal SI, such that the vehicle monitoring region (8) and the fire detector monitoring region (12) overlap, wherein the vehicle (2) is configured to detect the fire parameter KF at the target location (16) by means of the vehicle sensor unit (6) as a verification fire parameter KV of the fire detector monitoring region (12), wherein the vehicle (2) is configured for determining a verification fire status ZV by evaluating the verification fire parameter KV, wherein the vehicle (2) is configured to determine the reference fire status ZR as a verified reference fire status ZVR, if the reference fire status ZR and the verification fire status ZV sufficiently correspond, and to initiate a fire extinguishing action in the event of a verified reference fire status ZVR. The invention also relates to a system (20) having a vehicle (2) of this type, as well as a corresponding method.
