How a deluge sprinkler system works?
A deluge fire protection system has unpressurized dry piping and open sprinkler heads. The system is directly connected to a water supply and when the system is activated, a deluge valve will release the water to all the open sprinkler heads. The valve is opened when activated by a heat or smoke detection system.
Can you turn off fire sprinkler system?
One option you have is to turn off the entire system by cutting off the water supply. This stops water from flowing into your home entirely, not just the sprinkler system. If you have a fire sprinkler system with a shutoff valve on the pipe that brings water to this system, you can turn off this valve.
How are deluge systems activated?
How is a Deluge System activated? The sprinkler heads on a Deluge system are fused together and operate as one when activated. The valve is opened when activated by heat or smoke detection systems. Once activated, the water is released into the piping and out of the sprinkler heads.
How do fire suppression sprinklers work?
Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the liquid expands, it shatters its glass confines and the sprinkler head activates.
At what temperature do fire sprinklers go off?
between 155 to 165 degrees Fahrenheit

Why is my sprinkler water pressure so low?
One of the leading reasons for low sprinkler water pressure relates to the valves on your backflow preventer device. If you notice limited water pressure in your sprinkler system but normal water pressure inside your home, then the problem might be that your backflow preventer valves are not completely open.

What causes low pressure in one zone of sprinklers?
Timer problems are the most common cause of intermittent low pressure in one sprinkler system zone. The timer for this zone may be a bit behind the others, causing a delay for full water pressure to reach the affected zone. Or, the timer may turn the zone on and off a few times or may not turn it on at all.
