Sloped Roof Fire Sprinkler Installation

Nfpa 13 also requires the use of false or dropped ceilings if ceiling inclines exceed 2 in 12 slopes.

Sloped roof fire sprinkler installation.

Excellent foam aspirating action. Flash roof sprinkler system supports up to 24. 50 foot diameter spray per sprinkler providing over 1200 sq ft of coverage per set. Asprhb33 horizontal base sprinkler.

Deploy on the roof of a structure and around the perimeter of a structure for complete fire protection coverage. Must be offset at least one channel laterally from any ridgeline sprinkler. The sloped ceiling may also alter sprinkler spray patterns depending on sprinkler installation details e g. Pipe slope is a critical element in reducing water collection following a sprinkler system drain.

For placement on a sloped surface such as a roof a sub base of wood could be constructed to compensate for the slope or sand bags can be used to achieve that objective. A project that contains a light hazard office space with a dry pipe sprinkler system and a 900 sqft area with sloped ceilings about a 5 12 pitch. When compared to standard spray sprinklers which have restricted nfpa 13 installation criteria within attic spaces the models bb sd hip and ap sprinklers fig. Roofs having a pitch not exceeding 2.

Installation with fewer sprinklers installation with fewer branch lines a hydraulic advantage. Here is a quick summary of the minimum pipe slope requirements for fire sprinkler systems. However where sprinklers are installed in the peak below a sloped ceiling or roof surface the sprinkler shall be installed with the deflector horizontal. These modified transport dynamics may increase the suppression challenge through increased fire size.

Ensure that the sprinkler deflector is installed with the deflector parallel to the sloped roof above. Structural fire protection that is quick and easy to set up. Water removal is important in that the largest detriment to sprinkler system life corrosion occurs across interfaces between air and water. Sprinkler deflector orientation is outlined by fm global data sheet 2 0 installation guidelines for automatic sprinklers 3 and requires parallel to the floor installation.

Deflector orientation and or standoff distance. 12 16 7 are considered horizontal and sprinklers shall be permitted to be installed with deflectors horizontal.
