FORMATION OF THE FIELD OF FIRE DETECTOR GRADING METHODS
Array
Keywords:
fire detector, fire development, false alarm.Abstract
The possibility of grading the range of fire detectors of smoke detectors is considered in order to increase their functional properties. The typical composition of the elements of the sensitive part and the design of the existing smoke detector model of domestic production IPD-A is analyzed. The influence of the causes of false positives on the operation of the detector in the automatic fire extinguishing system are considered.
The results of the practice of operation and maintenance of the systems of automatic fire extinguishing system with normative indicators have been synthesized. Based on them, a summary scheme of the development of fire in the room was built. The list of reasons for false alarms is given. The general method of calibration of the fire detector has been formed. On the basis of the latter is proposed the concept of an advanced graded fire detector smoke, which has additional parameters for adaptive tuning, with improved performance.
The problem of formation of the general method of calibration of the fire detector is solved in the work, taking into account the characteristics of the fire load. For this purpose, a summary scheme for the development of a fire in the room was developed for the purpose of demonstrating changes in the temperature of gases, and materials whose combustion actively affects the overall temperature of the gases in the room at each stage of the fire per unit time;
4) A description of the design elements of the existing domestic smoke detector IPD-A;
5) The list of common false positives was analyzed on the basis of practical operation and maintenance of the detector;
6) A graded fire detector with basic elemental differences from the existing detector is proposed to improve the quality of operation.
The concept of an advanced graded smoke detector, with additional parameters for adaptive tuning, with improved performance, is proposed to be developed on the basis of the design of a typical existing device for the purpose of improved firing capture by hardware.
