At Kauffman Co., we believe that an intelligently designed sprinkler system is the single most important thing you can have in your building to keep it safe from fires at all times. And the most important aspect of fire sprinkler installation is making sure your sprinkler heads are located in the proper places to provide the best coverage.
There are two main criteria for determining the location of sprinkler heads:
When properly installed, most sprinkler heads will have an 8’ coverage radius. This is one of many determining factors in how the sprinkler heads must be spaced.
The NFPA lays out specific spacing requirements for sprinkler heads. These requirements are based on hazard level as well as pump flow calculations and may need to be adjusted based on any obstructions that may be present in the area of the sprinkler head.
|Hazard Level||Coverage (in sq ft) per Sprinkler Head||Maximum Allowed Distance Between Sprinkler Heads|
|Light Hazard (areas with low concentrations of flammable materials)||130-200 sq ft per head||15 ft|
|Ordinary Hazard 1 & 2 (areas with moderate concentrations of flammable materials)||130 sq ft per head||15 ft|
|Extra Hazard 1 & 2 (areas with a high concentration of flammable materials)||90-130 sq ft per head (based on obstructions and flow calculationss)||12 ft|
Other sprinkler head spacing requirements include:
* Most sprinkler heads will be installed 1″ from the ceiling. Concealed, recessed, or flush-mounted sprinkler heads may be listed for shorter distances.
If your building needs more protection than you can get with a standard coverage fire sprinkler, or if heads cannot be installed to meet normal spacing requirements, you may need to install extended coverage sprinkler heads. These sprinkler heads have an increased radius of approximately 10 ft and can be spaces about 20 ft apart. At Kauffman Co., our fire sprinkler design engineers will take your specific building factors into consideration to install a fire protection system that will keep you safe at all times.
