What is the maximum distance of sprinkler head from walls?
5.2. 1 of NFPA 13, which states that the distance from the sprinkler to the wall can be no more than one-half the allowable distance between sprinklers. The max distance between standard spray sprinklers in light hazard settings is 15 ft. (4.6 m) (with exceptions for light-hazard, combustible concealed spaces).
What is the minimum distance between a sprinkler head and any obstruction?
1 foot
What is the minimum distance between two sprinklers without any obstruction in between?
A sidewall sprinkler can’t be installed less than four feet from an obstruction unless: The greatest dimension of the obstruction is less than two feet. In that instance, the sprinkler must be at least three times that dimension away from the obstruction.
How far does a sprinkler head have to be from a light fixture?
The sprinklers spray at an angle of approximately 45 degrees. So of your light fixture is 4 inches deep, then you should keep them at least 4 inches away from the sprinkler heads.
How do you clear a clogged sprinkler?
Sprinkler heads contain a small plastic filter that should also be checked routinely for signs of clogging. Unscrew the nozzle of the sprinkler and pull out the filter to see if it’s dirty. Running the filter under cold water will remove any dirt. Flushing a sprinkler line will remove dirt and other debris.
What is the difference between NFPA 13 and 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.
What is the closest distance that items can be stored from a ceiling without any sprinkler heads?
Storage shall be maintained 2 feet (610 mm) or more below the ceiling in non-‐sprinklered areas of buildings or a minimum of 18 inches (457 mm) below sprinkler head deflectors in sprinklered areas of buildings.
Can you hang things from sprinkler pipes?
There should never be anything hanging on the sprinkler pipes, sprinklers or the sprinkler guard, as such decoration can block or obstruct the sprinkler system’s full coverage.
How much clearance is required below or around a sprinkler head?
As a general rule, NFPA 13, Installation of Sprinkler Systems, requires 18 inches of clearance, but makes the following modifications: For standard pendent and upright spray (SSP/SSU) sprinklers, the 18- inch dimension is not intended to limit the height of shelving or storage along a wall as illustrated below.
What is the minimum clearance required below ceiling mounted sprinklers?
The minimum vertical clearance between sprinklers and material below shall be 18 inches (45.7cm).
How Low Should sprinklers be?
The correct height for a sprinkler head is to have the top of sprinkler head just above the soil surface. No more than a quarter of an inch above the ground level. This lowers the tripping hazard, and a lawn mower can go past it without causing any damage.
Can I mix and match sprinkler heads?
While you can mix different brands in the same zone, don’t mix the type of head because they have different flow rates. Rotor heads, spray heads, matched precipitation etc all throw water at a different rate.
Can you mix rotary and spray sprinklers?
If you set that same irrigation zone to run based on the precipitation rate for your spray heads, well then they’ll have an adequate amount of water, but the areas with the rotors or rotary nozzles are going to be severely underwatered, so you don’t want to mix them.
