What are the applications of civil air defense display signal light box in life?

Civil air defense signal lights are useful in wartime, but they are useless in peacetime.

Civil air defense signal lights are mainly used in wartime to indicate what kind of protective ventilation state the protection unit is in:

Green - clean ventilation;

Yellow type - filter type (filter) ventilation;

Red - Isolated ventilation.

It is generally installed in the ventilation machine room and the entrance and exit door of the personnel in the protection unit, facing the unit.

A large number of civil air defense control boxes|Control cabinet, civil air defense equipment control box, civil air defense signal control box, 1. Use.

Special device for underground engineering (civil air defense) is used for command transmission and alarm signal display for the conversion of different protection and ventilation modes of fortifications in wartime.

Second, the signal device composition.

This device is composed of a command end through signal control box and a number of signal boxes at the receiving end, and the control box has 6 channels and 12 channels of output. Because the command terminal also has a signal input, and adopts unified signal parameters, this device can be used not only for the ventilation signal system of individual fortifications, but also for the formation of a hierarchical signal system in the civil air defense area fortification group, so as to realize the unified command and operation of the area in wartime.

3. Characteristics of the device.

a. It has the function of sending and monitoring, and can find the signal transmission failure in time;

b. It has a reply signal at the receiving end, and can timely grasp the execution status of each duty post;

c. It can carry out system self-inspection and test, which is convenient for maintenance and management;

d. Strong versatility, the system can be expanded arbitrarily, and is suitable for civil air defense fortifications and areas of various scales.

Fourth, technical specifications.

Fifth, the appearance of the ruler.

12-way control box, wall-mounted, 500, 600, 200, 4-hole, 13x18, 380, 630

6CH control box 400 500 200 4-hole 13x18 280 530

Signal box 560 120 100 2 holes 340

Note: 1. The ventilation signal control box is generally located in the anti-chemical communication duty room.

2. AS1 ASN: Ventilation signal indicator box, which is high on the inside of the innermost closed door of the air inlet room, exhaust fan room, diesel generator room, power station control room, personnel entrance and exit (communication port) and other places that need to be set up in wartime. The quantity is determined by the individual engineering design.

3. The audio signal button in the wire enclosure frame should be installed on the outside of the first protective closed door of the main entrance. The audio signal button should be guarded.

4. The P1 PN, PG1 PGN, PR1 PRN, and PY1 PYN in the fence frame are installed in the signal box of each ventilation mode.

Civil air defense equipment mainly includes, such as 1, reinforced concrete protective airtight door 2, airtight door 3, hanging plate valve 4, hose door 5, explosion-proof floor drain 6, airtight valve 7, oil network dust collector 8, mixed-flow fan 9, civil air defense flange 10 ventilation signal box, etc. Many, many, you have to use this to write **, you have to first understand what the air defense basement is.

Yours should have an entry point! Summarize the civil air defense products as a whole, and then enter into in-depth research from one aspect.

On pages 12 and 13 of the Civil Air Defense Atlas.

building electrical or facility inside.

The civil air defense ventilation signal light box is generally used with the civil air defense control box and the civil air defense call button.

The light box is connected to the control box with 5 wires, three of which are connected to the control box by three groups of bulbs, and one is connected to the electric bell, and there is a common wire between the light box and the control box.

Tell you clearly, the civil air defense ventilation control box belongs to strong electricity, and the control equipment also belongs to strong electricity, and the control box is a secondary circuit composed of strong current components such as relays.

The general light box should wear four wires as well I hope it can help you, please click "Praise", thank you

The red is the ** line, and the white is the speaker line.

The intelligent control system of the civil air defense engineering protection unit has been developed, and you don't have to worry about it.

1. The signal control box of the three ventilation modes only controls the signal light box and its sound effect, does not control the fan, and does not have the ability to convert and control the ventilation mode;

2. If you want to control the fan, it is very simple to do, but it is impossible to realize the conversion of the three ventilation modes by only controlling the fan;

3. The conversion of ventilation mode was originally manually converted (except for high-level civil air defense projects equipped with intelligent control systems);

4. The call button can not realize intercom, only equivalent to a doorbell, telling the management personnel in the project that there are external personnel to enter, and checking whether the ventilation mode, operation indicators, and anti-chemical detection personnel meet the conditions for personnel to enter from the main entrance and exit (the ventilation mode is filtering; Internal overpressure design value; Minimum number of ventilation and ventilation of the anti-virus channel The minimum number of ventilation changes is designed, and there are anti-chemical detection personnel and are in place in the dressing inspection room).

Tell you clearly, the civil air defense ventilation control box belongs to strong electricity, and the Qizao control equipment also belongs to strong electricity, and the control box is a combination of strong current components such as relays and accompanies the side limbs into a two-lu circuit.
