Indoor fire sprinklers are generally divided into, smoke alarm and heat source alarm, smoke alarm is the smoke needs to reach a certain degree to alarm water spray, and heat source alarm is the temperature to reach a certain degree so that the glass tube inside will be broken before spraying water.
Depending on the temperature of the kitchen, the preparation room, cold food room, storage room, etc. can use 68 degree sprinklers, and the operation room, staple food room, etc. should use 93 degree sprinklers.
This can be treated with 25 galvanized steel pipes with extended downdraft.
If this is short, lengthen the lower lead tube, use the pipe hoop to lengthen, if the short one is not big, you can try the concealed nozzle.
As long as the sprinkler head of this ceiling is closed to the ceiling, the spray is flat with the ceiling, and the maximum spacing of the sprinkler is not exceeded.
