applied to centralized control pulses, resulting in a large number of objects.

The purpose of the invention is to increase the information content and reliability of the device.

The imp is a diagram of the proposed device.

The device for multipoint alarm contains a source of power supply 1, a buzzer 2, a pulse generator 3 with opening contact 45 an acknowledgment button 5, a reset button 6, a control button 7, objects sensors 8, 9 alarm cells 9, each of which is received from the receiving relay 10 with closures II pins 11 - IS, relay of 14 wiring with clamping 15 and expanding 16 contacts and switching 1 contacts, diodes 18-24, ijesHCTopa 255 light indicator 36, intermediate relay 27 with disconnecting 28 and closing W 29 and 30, button 31 control l light alarm.

The device works as follows o

In the initial state, when the sensors 8 of the control objects are switched on (open) 5 buzzer 2, the generator 3 pulses, intermediate turnips 27, as well as the receiving relay 10, the relay 14 and the warning lights 26 of the alarm cells 9 are de-energized.

When any sensor 8 monitoring the object from the power supply source is switched on, the power supply is applied to the diodes 21 and 23 of the corresponding cell 9 C from the power supply output. In this case, the warning lamp 26 of the relay 10 is turned on. When the relay 10 is turned on, its contacts are closed. The closing contact 11 of the relay 10 self-locks it and turns on the intermediate relay 27. When the intermediate relay 27 is turned on, its opening contact 28 opens and diverts the supply voltage of the relay 10, excluding the possibility of turning on the relay 10 in any of the other cells 9 alarms when any other sensor 8 controls the object.

The horn 26 illuminates in pulsed mode.

Thus, turning on the sensor

The object control 8 is accompanied by an impulse light signal of the corresponding light signaling device 26 and an uninterrupted sound signal of the sound signaling device 2.

To remove the sound signal detected by the operation of the first on relay 10, it is necessary to briefly press the 5 acknowledgment button. At this, the acknowledgment relay 14 is turned on and becomes self-blocking. In this case, the switching contact 17 of the acknowledgment relay 14 switches the warning lamp 26 to the equal luminescence mode, and opening the contact 16 of the acknowledgment relay 14 disconnects the power supply of the intermediate relay 27. The intermediate relay 27 turns off, opens its closing "pins 29 and 30 in the power supply circuit of the buzzer 2 and

generator of 3 pulses, the disconnecting contact 28 of the intermediate relay 27 closes. In this case, the sound of the signaling device 2 and the generator of 3 pulses are turned off, and the closed contact 28 of the intermediate relay 27 stops the power supply circuit of the relay 10.

If after acknowledgment the sensor 8 of the control of any other object is turned on, then in the corresponding cell

and a warning lamp 26, as well as an intermediate relay 27, a warning lamp 2 and a generator of 3 pulses

Further operation of the multipoint alarm device is carried out in an analogous manner. But in any case, after acknowledging, switching on any other sensor 8 for controlling the object is accompanied by the deactivation of the warning lamp 26 and the cracking of it among the previously switched on glow, as well as by the activation of the acoustic signal.

When the object returns to its initial state, the object monitoring sensor 8 is turned off and relieves power from the acknowledgment relay 14. In this case, the diodes 2i and 23 are locked, the relay 14 of the acknowledgment 14 is turned off, and the pulses are received, which results in light.

The warning lamp 26 is pulsed.

Thus, turning on the sensor

The object control is accompanied by an impulse light signal of the corresponding light signaling device 26 and an uninterrupted sound signal of the sound signaling device 2.

In order to remove the audio signal caused by the operation of the first on relay 10, it is necessary to briefly press the acknowledgment button 5. At that, the acknowledgment relay 14 is turned on and becomes self-blocking. In this case, the switching contact 17 of the acknowledgment relay 14 switches the warning lamp 26 to the equal luminescence mode, and the disconnecting contact 16 of the acknowledgment relay 14 breaks the power supply circuit of the intermediate relay 27. The intermediate relay 27 turns off and opens closing the contacts 29 and 30 in the power supply circuit of the buzzer 2 and

generator 3 pulses, the disconnecting contact 28 of the intermediate relay 27 is closed. In this case, the buzzer 2 and the generator of 3 pulses are turned off, and the interlocking relay 28 of the intermediate relay 27 restores the power supply circuit of the relay 10.

If after acknowledgment the sensor 8 of the control of any other object is turned on, then in the corresponding cell

9 signaling switches on 10

and a warning lamp 26, as well as an intermediate relay 27, a warning lamp 2 and a generator of 3 pulses.

Further operation of the multipoint alarm device is carried out in an analogous manner. But in any case, after acknowledging, turning on any other sensor 8 for controlling the object is accompanied by lightening the warning lamp 26 and cracking it among the previously switched on light, as well as audible signaling.

When the object returns to its original state, the object monitoring sensor 8 turns off and removes the supply voltage from the acknowledgment relay 14. In this case, the diodes 2i and 23 are locked, the acknowledgment relay 14 is turned off, the receiving pefie 10 remains switched on by its own contact 11. The warning lamp 26 also remains plugged in. When the handshaking relay 14 is turned off, its disconnecting contact 16 closes and, through diode 22, the supply voltage enters the coil of intermediate relay 27, which turns on, including an acoustic alarm 2 and a pulse generator 3, disconnecting contact 4 of which periodically turns on the warning light 26, which is lit in the pulse mode, but with a reduced luminescence intensity, because a current limiting resistor 25 is turned on in the power supply circuit of the light detector 26.

Therefore, turning off the sensor

8 control of the object is accompanied by the mi- 20th of this, the supply voltage enters the

with a dimming light signal of reduced intensity of luminescence of the corresponding light signaling device 26 and a continuous sound signal of the sound signaling device 2.

To remove the sound signal and reset the light signaling notifying that the object control sensor 8 is turned on, briefly press the reset button 6, and the relay 10 is de-energized in the switch-off sensor 8 circuit and the intermediate relay 27, which turn off the acoustic alarm 2 and the pulse generator 3 .

Consequently, the information about the turned-off sensor 8 of the control of the object is reset, the warning lamp 26 of the corresponding alarm cell 9 does not carry false information, and the alarm cell 9 is ready to receive new information.

For periodic.control of the health of the signaling devices 26 is the button 31 control light alarm. When the light control button 31 is pressed, the light-emitting elements of the operable lights of the signaling devices 26 are fixed in a steady state.

A complete health check of all elements of the device is performed in stages.

To check the health and test the 9 signaling cells, the intermediate relay 27, the buzzer 2 and the pulse generator 3, when the sensors of the objects are controlled by the sensors 8, the button 7 is used.

Alarms and diodes 18. When the button 7 is pressed, the supply voltage through the diodes 18 of the alarm cells 9 goes to diodes 21 and 23. In this case, the operational light signaling devices 26 turn on, and the receiving relays 10 also turn on and become self-blocking. The closing contact 11 of the receiving relay supplies the supply voltage to the coil of the intermediate relay 27, the buzzer 2 and the pulse generator 3 are turned on, and the 26 warning lights of all the healthy alarm cells 9 are pulsed.

the windings of the acknowledgment relays 14, including the operative acknowledgment relays 14. If all relays 10 and all of the acknowledgment relays 14 are intact and switched on, then the supply voltage is removed from the winding of the intermediate relay 27, the intermediate relay 27 is turned off, turning off the buzzer 2 and the 3-pulse generator. At the same time, the light signaling devices 26 are switched to the steady glow mode.

In order to check the alarm circuits and the operation of the device, when the sensors for monitoring 8 objects are returned, it is necessary to release the alarm control button 7. In this case, the acknowledgment relay 14 is turned off, and the relay 10 is held in the on state by the closing contacts 11 in the self-blocking circuit, and the warning lamps 26 also remain on when the power supply circuits are in good condition. When the acknowledgment relay 14 is turned off, their disconnecting contacts 16 are closed, and through diodes 22, the supply voltage enters the coil of intermediate relay 27, which turns on and closes its contacts 29 and 30 in the power supply circuit of the buzzer 2 and the pulse generator 3. The buzzer 2 and the 3-pulse generator are switched on, the light-signaling devices 26 with serviceable supply circuits are hot in a pulsed mode, but with a reduced luminous intensity, otherwise they are extinguished.

The circuit is reset to its initial state by pressing the button with i.; 6poca, circuit 1 is opened: blocking relay 10, relay 10 is turned off, light warning lamps 26 are turned off, intermediate relay 27, buzzer 2 and pulse generator 3 are turned off.

A complete check on the functioning of all the elements of the scheme should be carried out after repair or preventive maintenance. Therefore, the operator only needs the acknowledgment button 5, the reset button 6 and the test button for checking the light signaling, and the alarm control button 7 should be protected against accidental pressing, for example, located under the transparent flap.

When the supply polarity is changed, the polarity of all the diodes in the circuit changes to the opposite.
