SECURITY ALARM, BASIC PARAMETERS, CLASSIFICATION AND DIAGNOSIS
The article discusses the analysis of the functional - parametric scheme of security alarm from the point of view of diagnostics. It is proposed an expanded classification of the security alarm of 24 signs with sub - signs in the amount of 2 to 8. Particularly significant features are: protection zones, the area of coverage of the object, the configuration of the detection zone, the scale of application, cost, etc. Proposed theoretic - multiple description of the elements of the security alarm in the form of general parameters and additional. A functional scheme of security alarms consisting of detectors - sensors, communication lines, receiving - control device and remote alarm (light and audible) is presented, the corresponding mathematical ratios and characteristics of the alarm train are presented. The method of diagnosing the security alarm in the form of an algorithm of 28 blocks using the equivalent of a plume, allowing for 3-4 procedures to determine the fault is proposed.
