Talking about Hotel Fire Spraying

The nozzles installed in the hotel are divided into downward spraying, side spraying and concealed spraying. The sensing temperature is 68 and 93, the normal room is 68, and the high temperature environment such as hotel kitchen is 79 and 93.

When smoking in a hotel, as long as the window is opened, it will not cause an alarm. Only when the smoke detector installed in the room reaches a certain smoke concentration, the alarm will start.

When the hotel fire alarm detector alarms, confirm it first, and then start the fire sprinkler pump to put out the fire when there is a fire.

Generally, the automatic fire sprinkler pump can be started in three ways:

1. In case of fire, reach the nozzle crushing temperature, make the nozzle rupture and spray water, make the water flow indicator in this area act, and send a signal to the fire control center. At the same time, the water flow of the alarm valve group causes action, which drives the hydraulic alarm bell to sound. The pressure switch on the alarm valve group acts at the same time to automatically start the spray pump.

2. The fire monitoring center can start the spray pump in the control room after receiving the fire alarm signal and confirming the fire.

3. Manually start the spray pump directly in the water pump room.
