What is a 13 sprinkler system?

NFPA 13 is a stricter standard for sprinkler installations designed to protect people and property from fire. Its systems aim to control fires close to where they start—wherever that may be—even if there is a lower direct risk to life safety.

What does NFPA 13 cover?

The purpose of NFPA 13 is to provide a reasonable degree of protection for life and property from fire through standardization of design, installation, and testing requirements for sprinkler systems (including private fire service mains) based on sound engineering principles, test data, and field experience.

What is the difference between a 13D and 13R sprinkler system?

The biggest difference between the three versions of NFPA 13 is the audience they serve and the allowable omissions within 13D and 13R. NFPA 13 and 13D focus mainly on life safety and property protection, while NFPA 13R strictly focuses on the life safety aspect.

When can NFPA 13R be used?

Buildings must be residential, four stories or less, 60 feet in height or less, ​and not use any code exemptions for an NFPA 13 system in order to use NFPA 13R.

How many sprinkler heads can you put on one line?

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.

What is the most common type of fire sprinkler?

Wet pipe systems
Wet pipe systems are the most common type of fire sprinkler systems. These systems are filled with water from an automatic source, and when a sprinkler head is exposed to enough heat, the heat-sensitive element will release and water will be allowed to flow from that sprinkler.

What is the current NFPA 13 edition?

The 2022 edition of NFPA 13, Standard for the Installation of Sprinkler Systems, is the transformative next step for designers, engineers, contractors, and installers involved with water-based fire protection in today’s world.

How many gallons per minute does a fire sprinkler head use?

A typical fire sprinkler design requires 26 gpm, which is fine for 3/4-inch and 1-inch meters, but exceeds the maximum flow for 5/8-inch meters. One solution would be to use low-flow sprinkler heads to lower the system demand at or below 20 gpm.

Is it bad to water grass at night?

If you must water in the evening, try between 4 and 6 p.m. which should give the grass blades time to dry before nightfall. The later you water, the greater chance of disease becoming prevalent in your lawn. It’s worth noting, though, that you don’t necessarily have to water your lawn.

What is the difference between NFPA 13 and NFPA 13R?

In other words, NFPA 13R requirements provide for a level of protection that allows occupants to escape a building in the event of a fire. Conversely, NFPA 13 provides protection to not only get people out to safety, but also to control or extinguish the fire – saving the building and its contents.

How do fire 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 air is hot enough and reaches a sprinkler head, it triggers a chain reaction.
