Description

The utility model relates to systems that provide control and protection of the protected premises from unauthorized entry, as well as fire protection.

A well-known fire alarm system in which information interaction between guarded objects and a central monitoring point (CMS) is carried out via telephone communication lines (TLS), RU 94042351.

The disadvantage of this system is associated with the low reliability and efficiency of the information provided by the employed TLS. This is due to insufficient high-speed TLS, limited bandwidth and periodic employment of TLS. In addition, the reliability of wired communication lines is small and they are vulnerable to open circuit and short circuit in cases of deliberate failure of them.

Moreover, the subscriber unit contains a block of controlled switches of peripheral centers, RU 12472 U1.

This technical solution is taken as a prototype of this utility model.

The disadvantage of the prototype is the lack of the ability to remotely (from the monitoring station) transfer to the operating position of the computer of the RF and detectors located in the RF (arming), as well as the ability to remotely cancel such a command. This is significant in cases where in the RF there is no staff; in addition, in the prototype system there is no indication of the state of the RF and the operation of the subscriber unit of the RF, which is important when the service personnel is in the RF; there is also no possibility of influencing the situation in the RFP directly inside the RFP. Also, the disadvantage of the prototype is the fact that the system only provides information about the fire in the RF, but does not automatically provide the extinguishing of this fire.

The objective of this utility model is to provide the possibility of remote (from the monitoring station) transfer to the “guard” position of the computer of the protected premises and the detectors located in them and their remote disarming; In addition, the tasks of providing an indication of the state of the landfill and the operation of the subscriber unit of the landfill, providing the possibility of influencing the situation in the landfill while inside the landfill, as well as the possibility of extinguishing the fire when it is detected by fire detectors, are being solved; The problem of providing the possibility of monitoring and remote control of all the monitoring stations of the system from one common control and monitoring panel is also being solved.
