The invention relates to a system (20) for determining a verified fire status, having: an unmanned vehicle (2) comprising a vehicle sensor unit (6) for capturing a fire parameter KF, a central unit (22) for transmitting an instruction signal SI to the vehicle, and a stationary fire detector (14) comprising a fire detector sensor unit (28) for capturing a reference fire parameter KR of a fire detector monitoring area (12), wherein the fire detector (14) is designed for determining a reference fire status ZR and for transmitting a corresponding fire detector signal SB to the central unit (22), wherein the vehicle (2) is designed for navigating to the target location (16) on the basis of the transmitted instruction signal SI, for capturing the fire parameter KF as a verification fire parameter KV of the fire detector monitoring area (12) at the target location (16), and for determining a corresponding verification fire status ZV, and wherein the vehicle (2) is designed for transmitting a corresponding verification signal SV to the central unit (22), which can determine the reference fire status ZR as verified reference fire status ZVR, if the reference fire status ZR and the verification fire status ZV correspond. The invention furthermore relates to a vehicle, a method, and a central unit, each corresponding to the system (20).
