Abstract
A fire extinguishing system coupled with a guarding system for the protecting same region as covered by the fire extinguishing system, and provided with at least one intrusion sensor arranged at desired locations in the region. The fire-extinguishing system is provided with at least one fire sensor arranged in the region and at least one fire extinguishing device for extinguishing a fire, and is connected to the guarding system by a warning signal transmission device provided with a logic circuit for identifying three different conditions based upon whether the fire sensor(s) detects a breakout of a fire or not and whether the intrusion sensor(s) detects an intruder or not. The above-mentioned fire extinguishing system can be further coupled with a switching device for identifying conditions with regard to whether the fire extinguishing system and the guarding system are intentionally set in a self actuatable condition or not.
