The disadvantages of the known device are insufficient reliability of operation, since the device lacks periodic monitoring of the health of the main elements and there is the possibility of skipping an emergency situation.

The aim of the invention is to improve the reliability of the device. The goal is achieved by the fact that the alarm device contains a power source, the plus bus of which is connected to the object control sensors and connected to the reset and checkout buses, a pulse generator with a locking contact, a sound signal generator and control cells, respectively, through the reset and acknowledge buses. alarms performed on the on and off relays, decoupling diodes and signal lamps, a delay relay with an open contact, a test button and a test bus, a delay, and pulsed power and control, and additional diodes are inserted in the control and alarm cells, one output of the buzzer is connected to the impulse power bus, which is connected to the negative power supply bus through the shorting contact of the pulse generator, the other output of the buzzer is connected with a delay relay, pulse generator and control bus, in each control and alarm cell, one output of the acknowledgment relay is connected to the negative power supply bus, and the other output of the acknowledgment relay is connected to the enable relay and the acknowledgment bus, respectively, through its own first closing contact and through a serially connected first closing contact and an additional diode, one output of the switching relay is connected via its own second closing contact to the negative power supply busbar and through an isolating diode a delay bus which is connected via a break contact of the delay relay to the negative bus of the power source, and another output of the activation relay is connected to the corresponding sensor of the control unit They also connect their own third closing contact in series and the first opening contact of the handshake relay connected to the control bus, to the reset and test buses, respectively, via their own fourth closing contact and another uncoupling diode and directly to one output of the lamp, the other output of which Dinen with minus BUS of power source through parallel-connected disconnecting contacts of the activation relay and the second closing contacts of the acknowledgment relay, and with the pulse switching power supply neither through the series-connected fifth closing and second disconnecting contacts, respectively, of the on relay and the acknowledgment relay. 654 The drawing is a schematic diagram of the device for technological signaling. The device contains a source 1 p 1 tani with positive 2 and minus 3 power buses, button 4 and acknowledgment bus 5, button b and reset bus 7, button 8 and test bus 9, object control sensors 10, generator 11 with contact 12 and bus 13 pulse power supply, delay relay 14 with disconnecting contact 15 and delay 16, 16 control bus 17, buzzer 18 and control and alarm cells 19, which contain an acknowledgment relay 20, with closing 21 and 22 and opening 23 and 24 contacts, a relay 25 turn-ons with a closing 2630 and a disconnecting 31 strokes, diodes 32-34 and warning lamps 35. An apparatus for processing alarm operates as follows. In the initial state, when the contacts of the sensors 10 are open, the control and alarm cells 19, the pulse generator 11, the delay relay 14 and the alarm 18 are de-energized. When any contact of sensor 10 of the control object is turned on, the corresponding relay 25 on the circuit is turned on: positive bus 2 of power supply source 1, closed contact of sensor 10 of object control, relay 25 winding, diode 33, negative bus 16 delay, closed contact 15 of relay 14 of delay and negative tire 3 of the power supply source 1. When the relay 25 is turned on, its following contacts are closed: 27, which switches the bus 16 of its power supply to the common negative bus 3; 28, which by means of the closed contact 23 of the handshake relay 20 supplies power to the common control bus 17 and turns on the generator 11 of pulses, the relay 14 of the delay and the buzzer 18; 30, which pushes the signal lamp 35 by means of a closed contact 24 of the acknowledgment relay 20 to the negative bus 13 of the pulse supply. At the same time, contact 31 of the on relay 25 is opened and disconnects the signal lamp 35 from bus 3. When the generator 11 pulses is turned on, its closing contact 12 on the bus 13 causes a pulsed negative power supply and a signal lamp 35, in the circuit of which the sensor 10 is closed control objects begins to burn in a pulse mode, and the buzzer 18 emits a pulse sound signal. The included delay relays 14 through its open contact 15 de-energizes the delay bus 16, not

By the way, when the first sensor 10 controls the objects is turned on, its signal lamp 35 lights up in a pulsed mode, relays 25 and 14 are on, the generator 11 of pulses is working, and pulses an acoustic signal. alarm 18. In addition, through its closing contact 29, the switch-on relay 25 is self-blocked via the reset bus 7 through the reset button 6 and remains on even when its object sensor 10 is open, to implement the memory element.

Upon the subsequent closure of the contact of the sensor 10 to control objects of another monitored object, its turn-on relay 25 does not turn on, leaving its contact 31 closed, by means of which the lactate 35 of this cell is illuminated with a constant light through the negative bus 3.

In order to remove the audio signal of the first switching-on control unit 19 and the signalization button 4, the acknowledgment button is pressed, which, applying power to the acknowledgment bus 5, switches on the diode 32 and the closed contact of the relay 25 to turn on the acknowledgment relay 20 only for this control and signaling cell 19. When the acknowledgment relay 20 is turned on, its contact 23 is wired, which de-energizes the control bus 17 and turns off the buzzer 18, the delay relay 14 and the pulse generator 11, and the switch 24 opens, disconnecting this signal lamp 35 from the bus 13. At the same time, contact 21 of the relay closes 20 acknowledgment, which is set to self-blocking from reset bus 7 by means of the closed contact 29 of the turn-on relay 25. The signal lamp 35 is connected via a closed contact 22 to a permanently burning bus 3 .. I I

After acknowledging the newly generated signal from the closed contact of the sensor 10 of the control object leads to the inclusion of the corresponding on relay 25, and its signal lamp 35 is pulsed with simultaneous feeding of an audible signal.

Further operation of the system is carried out in a similar way. But in any case, after acknowledgment of the hygdie, the first signal from sensor 10 of the control of objects is highlighted with a blinking light by the corresponding signal lamp 35 with simultaneous supply of a pulsed sound signal.

By pressing the reset button 6, the tire 7 is reset, and all the control and alarm cells 19, the sensors 10 of which have been opened, i.e. objects are given

5 in good condition, de-energized. and the entire system returns to a de-energized initial state. To periodically check the health of control cells 19 and sig-10, generator 11 pulses,

Relay 4 delay and beep sound 18 uses the 8 test button. When pressed on the test bus 9, feed appears &

fJ which is supplied via diodes 34 to all of the on relay 25. As a result, a pulse generator 11, a delay relay 14, a buzzer 18 and hot warning lights 35 of all cells 19 are turned on.

20 control and alarm in pulse mode. After that, to check the operability of the acknowledgment relay 20 of all the control and signaling cells 19 and their contacts, the confirmation button 4 is pressed. As a result, the relay 20 handshakes of all serviceable monitoring and alarm cells 19 are turned on, and their signals lamps 35 by means of closed clocks 22 of the handshake relay 20 are evenly illuminated. Next, the reset button 6 is pressed, and the entire system returns to its original state. . .

The device contains minimal

40 Each newly switched on power or emergency shutdown object after acknowledging previous signals can be clearly distinguished from other signals, as among those already existing, 45 among those received after it, which significantly increases the conditions for monitoring the operation and health of monitored objects and creates all the necessary prerequisites for proper repair and prevent the development of an emergency.
