However where sprinklers are installed in the peak below a sloped ceiling or roof surface the sprinkler shall be installed with the deflector horizontal. Pipe slope is a critical element in reducing water collection following a sprinkler system drain.

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

Per nfpa 13 the remote area should increase by 30 for the dry system nfpa 13 2013 section 11 2 3 2 5 and another 30 for the slope nfpa 13 2013 section 11 2 3 2 4. Must be offset at least one channel laterally from any ridgeline sprinkler.

Deploy on the roof of a structure and around the perimeter of a structure for complete fire protection coverage.

Ensure that the sprinkler deflector is installed with the deflector parallel to the sloped roof above. Roofs having a pitch not exceeding 2. Non combustible sloped attic spaces and have been developed to produce unique water spray patterns to enhance sprinkler placement while improving fire control. Asprhb33 horizontal base sprinkler.

These modified transport dynamics may increase the suppression challenge through increased fire size. 50 foot diameter spray per sprinkler providing over 1200 sq ft of coverage per set. Installation with fewer sprinklers installation with fewer branch lines a hydraulic advantage. The sloped ceiling may also alter sprinkler spray patterns depending on sprinkler installation details e g.
