A utility model is illustrated in the drawing, where in FIG. 1 shows a block diagram of a fire alarm device.

The fire alarm device consists of individual fire alarm loops 1 with fire detectors included in them. Each individual loop is connected to a separate remote signal reception and registration module 2, which includes a loop servicing unit 3, a decision making unit 4, a notification transmission unit 5, an external circuit switch unit 6, an input of a loop servicing unit 3 connected to an individual loop, output the loop maintenance unit 3 is connected to

j ///% 3

-5in the input of decision block 4, the output of decision block 4 is connected to the input of the notification block 5 and to the input of the external circuit block 6. All modules 2 receiving and recording signals via communication lines 7 are connected to the module 8 control and management. The control and management module 8 includes an address notification receiving unit 9, an information processing unit 10, an indication unit 11, an external circuit switch unit 12, the output of the notification transmitting unit 5 of the signal receiving and recording module 2 being connected via a communication line 7 to the input of the unit 9 receiving address notifications, the output of block 9 of address notifications is connected to the input of block 10 of information processing, the output of block 10 of information processing is connected to the inputs of block 11 of the indication and block 12 of the external circuit switch.

Device for fire alarm operates as follows.

In the initial state, the detectors of all individual fire loops 1 are in standby mode. This state of the individual loop 1 is detected by the loop servicing unit 3 of the individual module 2 and transmitted to the decision block 4, which analyze the states of the individual loop 1 and the individual module 2 and issue a notification CORRECTLY to the notification transmission unit 5. Upon request from the module 8 control and management

is transmitted to the block 9 receiving address notifications and then to the side 10 of the information processing, confirming the operability of all elements of the system.

When one detector is triggered in a fire alarm loop 1, the loop service unit 3 of the corresponding signal reception and registration module 2 transmits a message about the named event to decision block 4. Block 4 decision making generates a notice ATTENTION, which through block 5 transmitting notifications via communication line 7 is transmitted to the module 8 control and management. Block 9 receiving address notifications receives the notification ATTENTION, assigns it the address of the module that transmitted the notification, and transmits the information to the information processing unit 10. The information processing unit 10 filters the information received from each of the signal reception and registration modules 2 / according to the majority rule "m from n, where" m is the number of notifications in, n consecutive polling cycles / and passes to block 11 when deciding on the reliability of the information indication notice ATTENTION and address of the transmitting module 2 of the reception and registration of signals. The indicating unit 11 gives out light and sound warning signals ATTENTION with an indication of the address.

-7 fire alarm loops 1, the loop maintenance unit 3 of the corresponding signal reception and registration module 2 transmits a message about the named event to decision block 4. Block 4 decision making generates a warning FIRE, which through blocks 5 of the transmission of notifications on the communication line 7 is transmitted to the module 8 control and management. At the same time, the decision making unit 4 issues a command to the external circuit switch unit 6 to turn on local smoke removal or warning devices. The block 9 for receiving address notifications of the monitoring and control module 8 receives the FIRE notification, assigns the address of the module that transmitted the notification to it, and transmits the information to the information processing block 10. The information processing unit 10 filters the received information and, when deciding on the reliability of the information, transmits a FIRE notification to the indication unit 11, while blocking the indication of lower priority notifications. At the same time, the information processing unit 10 issues a command to the external circuit switch unit 12 to turn on system-wide smoke removal or warning means. The indication unit 11 gives out the light and sound signals of the FIRE warning indicating the address of the signal receiving and registration module 2 that has sent this notification.

loop failure message. Block 4 decision making removes transmitted to the block 5 of the transmission of notifications and then to the communication line 7 notification CORRECTLY. Block 9 receiving address notifications module 8 control and management ceases to transmit at this address to block 10 information processing notification FIXED. The information processing unit 10 responds to this event by generating the address notification FAULT, which is transmitted to the indication unit 11. The indicating unit 11 gives out light and sound alerts MALFUNCTION indicating the address of the module 2 for receiving and registering the signals that transmitted this notification.
