Fire Sprinkler Coverage Radius

A single fire sprinkler can cover an impressively large area with modern fire codes allowing a single head to protect more than 200 square feet in some environments.

Fire sprinkler coverage radius.

This is important read it carefully. In some circumstances standard distribution sprinkler heads will not provide enough coverage. Extended coverage sprinklers have a water distribution radius of a little over 10 feet so they can be spaced approximately 20 feet apart. Minimum vertical clearance 14 ft.

Without this overlap it would be impossible to design sprinkler systems that provided uniform water continue reading sprinkler coverage nozzle. Extended coverage light hazard pendent and recessed pendent sprinklers k factor 5 6 model sw 20 and sw 24 extended coverage ordinary hazard horizontal sidewall sprinklers standard response k factor 11 2 model eloc extra large orifice concealed pendent sprinklers extended coverage quick and standard response k factor 11 2 series rfii. Sprinkler heads must be unobstructed to provide maximum flow to the areas that need it. 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.

Minimum inside turning radius 25 ft. It was recognized that obstructions can impact sprinkler coverage given the following code sections 6. Pattern development for standard upright or pendent spray sprinklers national fire protection association. Wheel loading with asphalt or concrete driving surface.

The industry benchmark for design and installation of automatic fire sprinkler systems nfpa 13 addresses sprinkler system design approaches system installation and component options to prevent fire deaths and property loss. Fire sprinkler distancing is set by local building codes but prescribed by national and international building associations. Sprinkler head location and coverage. This means they cannot be blocked.

There are two main criteria for determining the location of sprinkler heads. Keeping the sprinkler head within the heat pocket is vital to activating the system. The area watered by each sprinkler must overlap substantially the area watered by the adjacent sprinkler. Minimum and maximum distances between the most common sprinkler heads and from heads to walls receive careful attention in nfpa 13.

Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year. In these cases extended coverage sprinkler heads can be installed to increase the spacing between heads. Commercial and industrial installations differ from residential as do the materials used. Minimum width of fire lane 20 ft except multi family complexes 26 ft.

18 figure 10 impact of single and multiple obstructions on a k5 6 spray sprinkler operating at 25 psi. In buildings protected by properly designed and maintained fire sprinklers over 99. Minimum outside turning radius 45 ft except multi family complexes 51 ft.
