Fire detection system with increased electromagnetic hindrances resistance [Tyt.równol.]
Języki publikacji
Abstrakty
There is a description of the optical scheme of the laser fibre-optical smoke detector that provides increased electromagnetic fields stability in the fire alarm system using it as a fire detecting facility. Smoke detection by means of this detector is realized according to the radiation receiver reaction to the reduction of the light flux intensity registered by this receiver owing to partial absorption and dispersion on smoke particles. High noise immunity of the fire alarm system with the laser fibre-optical smoke detector is caused by the absence of the long electrically conducting supply and communication lines inputted to the detector from the receiving-monitoring device. Supply and communication lines play a part of the effective receiving aerials of the casual electromagnetic fields. Approbation results of the working capacity of the offered scheme are represented.
