Fire Sprinklers Installed For Sloped Roof

Centerline of sprinkler must be a minimum of 6 laterally from face of truss see figure 8.

Fire sprinklers installed for sloped roof.

The sloped ceiling may also alter sprinkler spray patterns depending on sprinkler installation details e g. Our roof sprinkler systems have been designed specifically for structural perimeter protection from urban interface wildland fires features include. Deflector orientation and or standoff distance. When compared to standard spray sprinklers which have restricted nfpa 13 installation criteria within attic spaces.

Sprinklers are one of the oldest methods but one of the newest technologies in wildfire control and property fire protection in wildland areas. Rooftop sprinklers are a proven method of improving the chances that a building will survive a wild fire according to various studies. In the face of an advancing wildfire a structure with a properly implemented firesmart program in combination with an operational exterior rooftop sprinkler system has a survival probability of above 90. 12 16 7 are considered horizontal and sprinklers shall be permitted to be installed with deflectors horizontal.

Must be offset at least one channel laterally from any ridgeline sprinkler. Sprinklers must be installed with the frame arms perpendicular to the roof slope. These modified transport dynamics may increase the suppression challenge through increased fire size. Roofs having a pitch not exceeding 2.

At higher roof angles the actual location of the fire source relative to the sprinkler locations produced increasingly skewed and decreased water flux patterns including a higher number of sprinklers activated. Deploy on the roof of a structure and around the perimeter of a structure for complete fire protection coverage. However where sprinklers are installed in the peak below a sloped ceiling or roof surface the sprinkler shall be installed with the deflector horizontal. For the 33 degree roof inclination equivalent to an 8 in 12 roof slope the water flux on top of the fire source is reduced by 50.

Deflector parallel to the sloped roof above. 50 foot diameter spray per sprinkler providing over 1200 sq ft of coverage per set. These sprinklers are specifically intended for use in combustible and non combustible sloped attic spaces and have been developed to produce unique water spray patterns to enhance sprinkler placement while improving fire control. When rooftop sprinklers are activated they spray water high up in the air which lands on the roof trees and other surfaces that are within range.
