What is the function of a sprinkler bell valve in a fire protection system?
A sprinkler bell valve in a fire protection system controls the flow of water to sprinkler heads. It opens when the system detects a fire, allowing water to flow and extinguish the fire.
How do fire sprinkler systems put out fires?
Fire sprinklers have two major components that operate in response to a fire: the fire sprinkler heads which are connected via a series of pipes to a fire pumps. Water pressure is kept in the head by a series of valves in the pump. and is kept in the heads by little vials of colored liquid. During a fire, the liquid inside the sprinkler heads heats up and starts to expand, eventually causing the vial to burst. Water that was kept in the pipes pours out of the sprinkler heads. The water pouring out of the sprinkler heads causes the pressure in the fire pump to drop. In response, the pump kicks on and pumps more water from the municipal water supply to keep the sprinkler flowing. NOTE: this is how "wet pipe" fire sprinklers, the most common types of fire sprinklers, work. Other sprinklers (dry pipe, deluge and pre-action) are slightly different.
How do you add zones to a fire sprinkler system?
Fire sprinkler systems are effectively already zoned - you don't need to do anything special. When your fire sprinkler system detects a fire, it doesn't set off all the sprinkler heads at once. Instead, each fire sprinkler head goes off when the temperature underneath it reaches a specific temperature, meaning only the ones affected by the fire will go off.
Where can one find more information about fire sprinklers?
Over 40 million fire sprinkler heads are fitted each year. A fire sprinkler is a component of a fire sprinkler system that discharges water onto fires in the area once the effects of a fire have been detected, such as excessive increase in temperature.
How does heat move from a fire up to a fire sprinkler?
Since hot air is lighter than cool air, heat, especially the high heat from a fire, moves up to the fire sprinkler heads on the ceiling the ceiling rapidly. When the heat gets too great, heat sensitive bulbs contained in the sprinkler heads burst and release pressurized water from behind the bulbs.

What does deluge mean in a fire sprinkler system?
A deluge fire sprinkler system, unlike most ordinary systems, mean that the sprinkler heads do not have individual heat-sensitive valves. The sprinkler heads in a deluge system have no valves of their own, meaning they are always open and water will be sprayed out of them when the supply valve is turned on. There are limited uses for deluge systems, such as in a tire storage warehouse where it is important to put out a fire quickly and the massive flow of water will not cause major damage.
How many fire sprinkler heads are needed for a fire department connection to be installed?
In the past the FDC was optional. NFPA 13: Standard for the Installation of Sprinkler Systems now requires the connection except for systems of 20 sprinkler heads or less, or when permission has been obtained from the authority having jurisdiction. Sources- Brannigan & Corbett- Building Construction for the Fire Service (4th Ed) 2008. The above is a direct quote on page 288 if you so need it for a paper. So when you have more than 20 sprinkler heads, or when you have obtained permission. Doug E.
What is the minimum distance sprinklers should be placed from the home?
National fire code requires at least 18 inches of separation from sprinkler heads to things stored beneath them.
