The hotel fire sprinkler flashes red.
There will be a flashing red light, indicating that it is working normally. Most hotels have this device, and so does our office building. At the end of each year, there will be building management inspection, pumping with pipes, sprinkler alarm, and then spraying water or foam to put out the fire.
Fire sprinklers are used in fire sprinkler systems. When a fire breaks out, it is put out by spraying water through the sprinkler splash plate, which is divided into drooping sprinkler, vertical sprinkler, ordinary sprinkler and side wall sprinkler. According to the definition in GB 5135.1.3.1,the nozzle is: under the action of heat, within a predetermined temperature range.
principle of operation
In general, fire sprinklers are installed on the wall or ceiling, connected to the water network pipeline filled with pressure, or a single sprinkler is installed along the pipeline to protect the area below it. In case of fire, the glass ball in the sprinkler will begin to expand when it encounters high temperature. When the expansion temperature exceeds the set value, the liquid will break the glass ball, and the water in the water pipe will flow out to put out the fire.
Sprinklers constantly spray water above the flame, which will completely extinguish the fire source in most cases, or at least control the heat to limit the generation of toxic smoke until the fire brigade arrives. In case of fire, the fire water will be spilled evenly through the sprinkler to control the fire in a certain area. Common nozzle types are: drooping type, upright type, ordinary type and side wall type.
