Description

The invention relates to automation and can be used for multipoint alarm systems.

The aim of the invention is to improve the reliability of the device.

The drawing shows a diagram of the device

The device contains signal cells 1, each of which is made of thyristors 2 and 3, resistors 4 and 5, diode 6 and lamps 7 and 8, forming the board 9, the source 10 of the pulsating signal, unit 1 1 of the audible alarm, resistive divider 12, made of resistors 13 and 14, current limiting element made in the form of resistor 15, buttons 16 and 17, sensors 18, test lamp key 19, power supply bus 20 and 21

The pulsing signal source 10 may be made of a relay 22 with a closing contact 23, a relay 24 with a closing contact 25, and a relay 26 with a closing contact 27

The sound alarm unit 11 can be made of transistors 28 and 29, a relay 30 with a closing contact 31, a resistor 32 and a transformer 33, a button 34.

The device works as follows.

When a violation occurs, the contact of the corresponding sensor 18 closes, applying a full voltage to the control of the thyristor electrode 2, which opens and connects the lamps 7 and 8 of the board 9 to the pulsing signal source 10. At the same time, the first current pulse triggers the sound alarm unit 11. Pressing the button 17 of the panel 9 translates into a steady glow mode. The voltage through the button 16 is applied to the control electrode of the thyristor 3, which opens, closing the thyristor 2 "

After the violation has disappeared, the contact of the sensor 18 is opened and the device returns to its original state.

The button 17 checks the thyristors 2 and 3 of the signal cells 1 s. Checking the lamps 7 and 8 of the board 9 is performed by the key 19 testing the lamps. In this case the lamps 7 and 8 are connected in series between the power supplies 20 and 21
