Designing a promising security alarm system requires solving a number of scientific problems. In the known publications, the features of formation and propagation of seismic waves in soil, influence of seismic sensors characteristics on the signal formation, seismic signal processing techniques, mathematical models of spatial and organizational structure of the protected object for making design decisions when determining the system hardware environment, are considered. Using the findings and recommendations of these studies allows improving the security alarm system efficiency. Another possibility to improve the security alarm system efficiency is to select a rational scheme of locating seismic sensors on the probable routes of objects moving to a stationary object. In practice of using the systems, there are schemes of probable routes for moving objects such as: four seismic sensors are located in far and near zones of control; two seismic sensors are located on the border in far or near zone of control; two seismic sensors are located sequentially in far and near zones of control; one seismic sensor is located either in far or near zone of control. To study the dependence of the system efficiency on the location of seismic sensors, mathematical models of the reaction of security alarm system at the appearance of a moving object were developed by the authors. One of these models, namely, the mathematical model of the system reaction to the appearance of the moving object with the location of four seismic sensors in far and near zones of control, is given in the paper. Description of the model development makes it possible to assess the level of its adequacy to the object of the study. Using the developed mathematical models, the dependence of the efficiency on the number of seismic sensors and schemes of their location on the probable routes is shown. In the studies, it was taken into account that the system efficiency is determined by sensitivity of seismic sensors and the system parameters: probability of correct classification of moving objects and probability of appropriate receiving the radio signal
