Description

The invention relates to the field _; automatic signaling and can be used in systems of centralized control and management of technological processes, in particular, 5 control ship technical equipment.

The aim of the invention is to reduce power consumption and simplify the device for multipoint signaling-10 zatsii.

The drawing shows a schematic diagram of a device for multipoint alarm,

The device contains a source of 1 15

supply, generator 2 pulses, button 3, alarm 4 (sound), signal cells 5, each of which includes diodes 6-10, signal lamp 11, resistor 12, relay with 20 winding 13 and switching contacts 14–16, closing Pin 17 of the parameter sensor, changeover pin 18 of the emergency sensor.

The device works as follows 25 times.

At normal values of the monitored parameters, the parameter sensor contact 17 is open, the relay coil 13 is de-energized, and the device does not require energy. When the contact 17 of the sensor parameter is closed, the generator of 2 pulses is started, which provides the glow of the signal lamp 11 and the operation of the alarm device 2 in intermittent mode. When the signal is acknowledged by pressing button 3, power is supplied to the winding 13 of the relay, after which it triggers and releases button 3, power is supplied to the winding 13 via contacts 18, 17 and 14. At that, the pulse generator 2 and the alarm 4 turn off, and the signal lamp 11 goes into constant light mode. The next time the emergency sensor contact 18 starts, the winding 13 of the relay is de-energized and its contacts 1416 return to the initial state shown in the drawing. When this starts, the generator 2 pulses, and the signal lamp 11 from the mode of constant light goes into the mode of intermittent light. At the same time, the alarm 4 is turned on in continuous mode. If then the switching contact 18 of the emergency sensor returns to its original state, then the intermittent nature of the light signaling is preserved, and the warning lamp 4 from the constant changes to the intermittent mode, ensuring that the emergency sensor 18 is activated.

After the alarm is fixed by pressing the button 3, the winding 13 is turned on, which, after the relay triggers, receives power through pins 8, 16 and 14. At the same time, the generator 2 of the pulses and the alarm 4 turn off and the warning lamp 11 switches to a constant light.

After returning the contact 18 of the emergency sensor to the initial state, the alarm characteristic of the sensor's response to the parameter is resumed and only after the return of the contact 17 of the sensor to the initial position does the signal cell 5 turn off.

The signal lamps 11 are checked by pressing the button 3. In this case, the winding 13 of the relay receives power, its contacts 14-16 are switched, and the signal lamps. 11 go into a steady glow mode.
