There is a red light flashing on the fire sprinkler in the hotel. Is that a camera?

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.

2. The system is equipped with an alarm device, which can automatically 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.

3. 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.

4, automatic control series, automatic control fire sprinkler system is a kind of fire extinguishing facilities that can automatically open the sprinkler to extinguish the fire and send out fire alarm signals at the same time. 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.

5. Usually the roof fire water tank is filled with water. In case of fire, when the temperature of the sprinkler reaches a certain temperature (generally 68℃), the chromium plating layer of the sprinkler melts, and the water in the pipeline is automatically sprayed out under the action of the roof fire water tank. At this point, the wet alarm valve will automatically open, and the pressure switch in the valve will also automatically open. This pressure switch has a signal line, which is interlocked with the fire pump, and the pump will start automatically. Then the spray pump supplies the water in the pool to the pipe network through the pipeline, and the whole fire fighting system starts to work.
