The layout of the nozzle is not a question of how many square meters are needed to install it. First, it is necessary to determine whether the building is a civil building, a factory building or a warehouse, then determine the danger level, and then determine whether it is sprayed up, down or sideways. If the ceiling is not hung, how to arrange between beams and other factors makes how many square meters to install a sprinkler become an uncertain number.

It is suggested to consult the specifications of automatic sprinkler system, design specifications of automatic fire alarm system and the use nature of buildings in the specifications. Explain in detail the feeling of spray and smoke.

If it is a general place, the indoor fire protection code stipulates that the height is less than 6 meters, the room area is more than 80 square meters, the maximum protection area of smoke is 60 square meters, and the protection radius is 5.9 meters. The smoke detector should be not less than 50 cm and not more than 750 cm away from the wall. This is a large area, and independent rooms, regardless of size, must be equipped with detectors.

The protection radius of nozzles is1.6m. The distance between nozzles is generally less than 3.6m, and the distance from the nozzle to the wall is between 0.8-1.8m. ..

About automatic sprinkler system

1, the fire sprinkler system is a kind of fire extinguishing device and a widely used fixed fire fighting facility, which has the characteristics of low price and high fire extinguishing efficiency. According to different functions, it can be divided into manual control and automatic control. The system is equipped with an alarm device, which can automatically give an alarm in case of fire. The automatic control fire sprinkler system can also spray water automatically and work synchronously with other fire control facilities, so it can effectively control and extinguish the initial fire.

2. Classification: Manual control series. Manual control means that when a fire breaks out, workers need to turn on the fire pump to supply pressurized water to the main pipeline, and the nozzle starts to work under the action of water pressure.

Automatic control series, automatic control fire sprinkler system is a kind of fire extinguishing facility that can automatically turn on the sprinkler and send out fire alarm signals at the same time in case of fire.

Automatic sprinkler system has the advantages of automatic sprinkler, automatic alarm and cooling initial fire, and can work synchronously with other fire-fighting facilities, so it can effectively control and extinguish initial fire. Now it has been widely used in building fire prevention. Automatic sprinkler systems are divided into smoke-sensing type and temperature-sensing type.

3. Application: Manual control series is generally applied to ships. Combined with the fire fighting system of the ship, pipelines are laid around the ship's cab and living area, and sprinklers are installed. When there is a fire on the ship itself or other ships.

When the fire fighting system works, the nozzles will spray at the same time to protect the cab and living area on board. Automatic control series has been widely used in civil buildings, public places, factories, warehouses and other places because of its low price, convenient use, safety and reliability.
