METHOD AND DEVICE FOR CONTROL TO PROTECT ALARM SYSTEM Russian patent published in 2017 - IPC G08B29/12 

FIELD: safety.

SUBSTANCE: present invention relates to a method and a device for control to protect an alarm system at a controlled object. Readiness of the alarm system to transmit an alarm signal from the object is controlled by the system control device, by means of which, at least, connections for transmitting data from the object are checked repeatedly in order to ensure the alarm signal transmission via one or more auxiliary alarm communication channels in case of disruption of the main alarm communication channel. Control device contains at least two control devices (1, 1'), which continuously monitor electrical connection/readiness of the object (K) with at least two of the following means:- a data transmission channel operating on a free frequency (within the ISM ranges), such as WLAN, Bluetooth, ZigBee networks and/or similar, – a mobile telephone network, such as NMT, GSM, GPRS, 3G, 4G networks and/or similar, – an electric network, – Internet, – one or more other control devices (1, 1'), – a communication connection operating on a free frequency (within the ISM ranges), such as channels with frequency of 902–928 Mhz, 2.4000–2.4835 Ghz, 5.728–5.850 Ghz and/or similar, – an alarm device as part of an alarm system, – a wire connection, such as ground telephone communication lines, ground communication lines between control devices and/or similar.

EFFECT: providing protection.
