There are two main criteria for determining the location of sprinkler heads.
Fire sprinkler coverage radius.
Commercial and industrial installations differ from residential as do the materials used.
18 figure 10 impact of single and multiple obstructions on a k5 6 spray sprinkler operating at 25 psi.
Keeping the sprinkler head within the heat pocket is vital to activating the system.
It was recognized that obstructions can impact sprinkler coverage given the following code sections 6.
Extended coverage sprinklers have a water distribution radius of a little over 10 feet so they can be spaced approximately 20 feet apart.
This overlap may seem like a waste at first but it is a very important necessity.
Minimum width of fire lane 20 ft except multi family complexes 26 ft.
Minimum inside turning radius 25 ft.
Minimum capacity 12 500 lbs.
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.
In these cases extended coverage sprinkler heads can be installed to increase the spacing between heads.
In some circumstances standard distribution sprinkler heads will not provide enough coverage.
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.
This means they cannot be blocked.
Minimum and maximum distances between the most common sprinkler heads and from heads to walls receive careful attention in nfpa 13.
Pattern development for standard upright or pendent spray sprinklers national fire protection association.
Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year.
Sprinkler heads must be unobstructed to provide maximum flow to the areas that need it.
Wheel loading with asphalt or concrete driving surface.
Minimum outside turning radius 45 ft except multi family complexes 51 ft.
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.
Fire sprinkler distancing is set by local building codes but prescribed by national and international building associations.
Because fire sprinklers are heat activated sprinkler heads must be located high up on or near the ceiling.
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.
This is important read it carefully.
The area watered by each sprinkler must overlap substantially the area watered by the adjacent sprinkler.
