The utility model relates to security and fire alarms (OPS) and can be used for centralized and autonomous protection of shops, cash desks, banks, pharmacies, institutions, enterprises and other objects from unauthorized entry and fires by monitoring the status of twenty alarm loops (AL), with security, fire and security-fire detectors included in them, and the issuance of alarm notifications about an alarm violation and the operation of the detectors via the Ethernet interface to the control and control panel or a computer, to the operator to the panel centralized monitoring through three relay outputs.

A known device is a security control and fire alarm PPKOP 01121-20-1 "SIGNAL-20P" (see Operation Manual, ATsDR.425533.001 RE, NVP "Bolid", Moscow Region, Korolev, 2001) including a microcontroller, to the input / output of which is connected to the channel switch, light indicators, keys, power supply loop reset circuit, non-volatile memory, reset button, tamper, monitors of the main and backup power supply, as well as a voltage converter for loop power (loop), loop modules , relay and power supply.

The disadvantages of the known device are: The RS-485 interface, when integrated into modern IT (information technology) infrastructure, requires the use of interface converters. As a backup power source, there is no possibility of using serial products such as Back UPS, since the input voltage control (220v) is not provided.

Thus, the device cannot be included in the local computer network without additional equipment (interface converter), as well as the unreliability of the device due to the inability to control the mains voltage (220v.)

The task of creating a utility model is to create an OPS device that allows you to work in any local Ethernet network without additional equipment, as well as increasing the reliability of the device as a whole.
