Abstract

The invention relates to an automatic multipoint alarm with a general sound and individual light alert and can be used in various sources of centralized monitoring of equipment and technological processes. The aim of the invention is to increase the reliability of information generated by the device, by eliminating the possibility of generating false information when the device returns to its original state. The device contains signaling cells, each of which is made up of four relay diodes with three closing and two opening contacts and indicators, a first pulse generator, a signal source, a reset button, a control button, an acknowledgment button, a sensor, and a buzzer. Fifth, sixth, and seventh diodes are inserted into each alarm cell, the relay is filled with the fourth make contact, and the signal source is designed as a second pulse generator. The introduction of additional diodes allows you to eliminate false information when the device returns to its original state 1 or less.

Description

The invention relates to an automatic multipoint alarm system with a general sound and an individual light alert and can be used in various systems of centralized control of equipment and technological processes.

The aim of the invention is to increase the reliability of information generated by the device, by eliminating the possibility of generating false information when the device returns to its original state.

The drawing shows a diagram of the device.

The device contains busses 1 and 2 of the power supply, control button 3, reset button 4, acoustic signal generator 5, acknowledgment button 7, sensors 8, alarm cells 9, each

which are made of diodes 10-16, relays 17c with closing 18-21 and opening contacts 22 and 23 of the signal lamp 24, and generator b of pulses.

The device works as follows.

In the initial state, when all monitored objects are in good condition and the sensors 8 are open, the alarm cells 9, the pulse generator 5 and the acoustic alarm 6 are de-energized. In case of an accident at monitored objects, sensor 8 closes, power is supplied from bus 1 through diode 14 to signal lamp 24 and then through diode 15 and disconnecting contact 22 of relay 17 to acoustic signaling device 6. At that, the warning lamp through disconnecting contact 22 of relay 17 and acoustic signaling device 6 works in a pulse mode through the generator 5 pulse about e

In order to remove the sound signal and transfer the signal lamp 24 to an even glow, the acknowledgment button 7 is pressed. As a result, through the sensor 8, the diodes 13 and 11 and the button 7 turns on the relay 17, which disconnects the buzzer 22 and the buzzer 6 and disconnects the generator 23 pulses, closes the signal lamp 24 and turns off self-blocking through the contacts 18 and 20, diode 12 and reset button 4.

When the previously faulty object is restored, the sensor 8 opens, the diode 16 opens and the signal lamp 24 through the already closed closing contact 21 of the switched on relay 17 and the pulse generator 25 turns on again in a pulsed mode, but with a different frequency.

To remove the reset signal, the reset button 4 is pressed, which, when opened, removes the self-blocking relay 17. In all the alarm cells 9, in which the sensors 8 are open, the relay 17 is de-energized and the signal lamps 24 are switched off. In the same alarm cells 9, in which the sensors 8 are in emergency operation, the reset does not occur, because remain connected through the diodes 13 and the corresponding sensors 8, so re-handshaking is not required, i.e. only the alarm 9 cells of the recovered objects are reset and go to sleep state.

. Periodic health check of the device is carried out as follows.

The control button 3 is pressed and held. At the same time, through the diodes 10 and 14, as well as the diodes 15, the warning lamps 24 and the buzzer 6 are switched on in a pulsed mode. Next, the acknowledge button 7 is pressed, which, turning on the relay 17, switches all the warning lamps 24 of the alarm cells 9 to an even glow and turns off the audible alarm device 6. Then the control button 3 is released and all signal lamps of the 24 signaling cells 9 are switched on again in a pulsed mode from the generator of 25 pulses. Next, the reset button 4 is pressed, all the signaling cells 9 are de-energized and return to the initial waiting state.
