Fire Sprinkler System Capacity

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

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. Although historically only used in factories and large commercial buildings systems for homes and small buildings are now available at a cost effective price. Next locate your system s static pressure and move down that column and find the system s working. 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.

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. Sprinkler water pressure is essential but how much is enough. 1 for situations where the jockey pump serves only above ground piping for fire sprinkler and standpipe systems. 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. 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. A fire sprinkler system is a critical component of life safety in a building. Every sprinkler system requires at least one automatic water supply of adequate pressure capacity and reliability.

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. The main fire pump should start and run providing a pump running signal for any water flow situation where a sprinkler has opened which will not.
