GAS FIRE DETECTORS APPLICATION AT ATOMIC POWER STATIONS
PURPOSE. One of the promising ways of increasing the efficiency of fire alarms is to control gas composition changes in the environment for early fire detection with low probability of false alarms. METHODS. Main characteristics analysis of initial fire stage in premises allows to improve the fire alarm system at the expense of new sensors in fire detectors. FINDINGS. Modern technologies make it possible to use such methods of detecting as oxygen concentration control with the help of thermomagnetic sensor in the environment. RESEARCH APPLICATION FIELD. Study results are relevant for application at the objects where early fire risk detection is necessary for preventing fire or explosion, which could cause an ecocatastrophe, loss of life or great property damage. Atomic power stations are such objects. CONCLUSIONS. To exclude false alarms it is proposed to use multi-sensor fire detectors which detect fire on several parameters, including gas control of the environment.
