Fire Sprinkler System Capacity

A fire sprinkler system is a critical component of life safety in a building.

Fire sprinkler system capacity.

A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected such as when a predetermined temperature has been exceeded. A fire sprinkler system is an active fire protection method consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system onto which fire sprinklers are connected. 1 for situations where the jockey pump serves only above ground piping for fire sprinkler and standpipe systems. Using the system design capacity chart on this page locate the three numbers you just recorded to determine the sprinkler system design capacity in gallons per minute gpm.

The jockey pump should be sized to provide a flow less than a single fire sprinkler. Next locate your system s static pressure and move down that column and find the system s working. Although historically only used in factories and large commercial buildings systems for homes and small buildings are now available at a cost effective price. Sprinkler water pressure is essential but how much is enough.

A building s water supply whether it s the municipal waterworks a well or a tank must have enough capacity and pressure to meet the demands of its fire sprinkler system and a pump must often augment pressure. Standard for the installation of stationary pumps for fire protection protects life and property by providing r equirements for the installation of fire pumps to ensure that systems will work as intended to deliver adequate and reliable water supplies in a fire emergency. Every sprinkler system requires at least one automatic water supply of adequate pressure capacity and reliability. The first step is to calculate the minimum flow which will be required at the most remote sprinkler which in this case is at node 130 this is a two step process as will need to calculate the minimum flow required to satisfy the 7 50 mm min design density and then find the flow rate from the sprinkler given the sprinklers minimum pressure requirement whichever is the greater flow will.

Record this number in the gpm box. Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year.
