Along with the prototype having a redundant power supply and the ability to control the communication channel, its disadvantage is low reliability due to the lack of redundancy of the communication channel and the main actuating element, the panic button.

The technical problem, the solution of which is provided during the implementation of the utility model, is to increase the reliability of the fire detector manual address radio channel due to the reservation of the communication channel and panic button.

The technical problem is solved by the fact that the fire detector is a manual addressable radio channel, consisting of a microcontroller with a transceiver, a radio quality control unit, an antenna at a frequency of 868 MHz, a power controller, a main power source, a backup power source, a tamper switch, a tear-off sensor mounting points, panic button, programming button, LED indicator, while a radio quality control unit is connected to the first input of the microcontroller with a transceiver montage, the first input of which is connected an antenna at a frequency of 868 MHz, the antenna at a frequency of 868 MHz is connected to the second input of a microcontroller with a transceiver, a power controller is connected to the third input of a microcontroller with a transceiver, to the inputs of which is a main power supply and a backup power source, to the fourth the tamper-evident sensor is connected to the input of the microcontroller with the transceiver; the detachment sensor from the point is attached to the fifth input of the microcontroller with the transceiver I, an alarm button is connected to the sixth input of a microcontroller with a transceiver, a programming button is connected to the seventh input of a microcontroller with a transceiver, an LED indicator is connected to the first output of a microcontroller with a transceiver, an additional alarm button and an antenna for a frequency of 433 MHz are introduced, while the second alarm button is connected to the eighth input of a microcontroller with a transceiver, an antenna at a frequency of 433 MHz is connected to the ninth input of a microcontroller with a transceiver and a second input quality control unit radio.

The utility model is illustrated by a figure, which shows a block diagram of the proposed device, which includes a microcontroller with a transceiver 1, a radio quality control unit 2, an antenna 3 at a frequency of 868 MHz, a power controller 4, a main power source 5, a backup power source 6, a sensor 7 opening tamper control, sensor 8 control the separation from the attachment point, panic button 9, programming button 10, LED 11, the second panic button 12 and antenna 13 at a frequency of 433 MHz.

At the same time, the radio quality control unit 2 is connected to the first input of the microcontroller with transceiver 1, the antenna 3 at a frequency of 868 MHz is connected to the first input of it, the antenna 3 at a frequency of 868 MHz is connected to the second input of the microcontroller with transceiver 1, and the third input of the microcontroller with transceiver 1 the power controller 4 is connected, the main power source 5 and the backup power source 6 are connected to the inputs of it; the control sensor 7 is opened to the fourth input of the microcontroller with the transceiver 1 I case, to the fifth input of the microcontroller with the transceiver 1 is connected the sensor 8 control the separation from the attachment point, to the sixth input of the microcontroller with the transceiver 1 the alarm button 9 is connected, to the seventh input of the microcontroller with the transceiver is connected the programming button 10, to the eighth input of the microcontroller with the transceiver 1 second panic button 12, the LED 11 is connected to the first output of the microcontroller with transceiver 1, the antenna 13 at a frequency of 433 MHz is connected to the ninth input an ode to the microcontroller with transceiver 1 and to the second input of the radio quality control unit 2.

The state of the fire detector of a manual addressable radio channel is set by the user on the device by the control and reception firefighter by transmitting to the microcontroller with transceiver 1 through antenna 3 or antenna 13 a signal carrying information about arming the fire alarm system and automatic fire extinguishing. At the same time, to establish the interaction between the detector fire manual addressable radio channel and the control panel fire control device is designed programming mode, the entrance to which is carried out by pressing and holding the programming button 10.

The microcontroller with the transceiver 1 receives power from the main power source 5 or from the backup power source 6, if the main power source 5 is discharged. It evaluates the state of the main power supply 5 and the backup power supply 6, and also switches the power controller 4 between them.

Depending on the state of the panic button 9 and panic button 12, the microcontroller with transceiver 1:

1) is in normal mode of operation in the absence of fire and, as a result, pressed alarm buttons;

2) issues a special warning alarm signal to the control panel of the firefighter, if the panic button 9 and / or panic button 12 is closed.

To indicate the specified operating modes, as well as the programming mode, the And LED is intended, which is usually a two-color / three-color LED.

In the event of a fire at the facility and the panic button 9 and / or panic button 12 closes, the microcontroller with transceiver 1 sends an alarm signal to the fire alarm control panel via antenna 3 or 13. Such a signal is transmitted over one of the available wireless networks at a frequency of 433 or 868 MHz. The choice of an available wireless network (reliable communication channel) is carried out by the radio quality control unit 2. The use of several communication channels is possible due to the use of a nRF9E5 Nordic Semiconductor chip system [https://www.google.com/search as a microcontroller with transceiver 1 ? q = nrf9e5 & rlz = 1C1CHBD_ruRU834RU834 & oq = n & aqs = chrome.0.69i5913j69i60j69i57j69i60.1829j0j7 & sourceid = chrome & ie = UTF-8].

Reservation of alarm buttons allows the microcontroller with transceiver 1 to generate and transmit a special alarm alert even if one of the alarm buttons fails. In this case, the panic button 9 and panic button 12 are implemented on various principles, one of them, for example, forms a mechanical contact, the second is magnetically contact. This solution improves the reliability of the fire detector manual addressable radio channel.

To exclude the possibility of disabling a special warning alarm, the manual fire detector addressable radio channel contains a tamper evident sensor 7, which is activated when the detector is opened, and a detachment control sensor 8, which is triggered when an detector is removed. At the same time, the microcontroller with the transceiver 1 transmits a special warning alarm signal to the fire alarm control panel, which is part of the fire alarm and automatic fire extinguishing system.

A new set of essential features allows to achieve a technical result, which consists in increasing the reliability of the fire detector manual addressable radio channel due to the reservation of the communication channel and panic button.

The analysis of the prior art made it possible to establish that there are no analogues that are characterized by a combination of features that are identical to all the features of the declared fire detector of a manual addressable radio channel. Therefore, the claimed utility model meets the condition of patentability “novelty”.
