Fire Sprinkler System Capacity

The jockey pump should be sized to provide a flow less than a single fire sprinkler.

Fire sprinkler system capacity.

In buildings protected by properly designed and maintained fire sprinklers over 99. 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. Next locate your system s static pressure and move down that column and find the system s working. A fire sprinkler system is a critical component of life safety in a building.

1 for situations where the jockey pump serves only above ground piping for fire sprinkler and standpipe systems. Sprinkler water pressure is essential but how much is enough. 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. Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year.

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. Although historically only used in factories and large commercial buildings systems for homes and small buildings are now available at a cost effective price. Every sprinkler system requires at least one automatic water supply of adequate pressure capacity and reliability. The water supply needs to be capable of supplying all sprinklers that operate during a fire and providing water for fire department operations during the fire.

Record this number in the gpm box. 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.
