Fire Sprinklers Alternative For Vaulted Ceiling Without Attic

If they are fuel fired units they are a source of fuel and a source of heat.

Fire sprinklers alternative for vaulted ceiling without attic.

Generally if they are not fuel fired units you do not provide sprinklers in the ceiling space. Unheated attic spaces to cover sprinkler piping completely with insulation. While models bb sd and hip are specific application attic sprinklers the model ap is a specific application combustible concealed space sprin kler with specific application criteria for use with models bb sd and hip. For individual areas requiring more than four ap sprinklers the maximum area of attic protected by ap sprinklers is limited to 3000 ft2 279 m2 in any sin gle area.

The sprinkler types that were studied included quick response ordinary temperature standard response and high temperature sprinklers. Areas must be separated by a minimum of 15 feet 4 6 m by an area protected by bb sd or hip sprinklers in order to be considered separate. Nfpa 13 installation of sprinkler systems the standard for the installation of automatic sprinkler systems never specifically addresses whether or not an attic requires sprinkler protection. Actuation of the ceiling sprinklers expected from a 3 dimensional growing fire load which is the most likely case of an accidental fire is 8 9 mw and that from a 2 dimensional plane pan fire is expected.

Gotta get sprinklers up there then. Would it make more sense to just install a metal roof to prevent the radiant heat penetration. Nfpa 13d does not require the following areas to have sprinkler systems. The starting point to determining if attics require sprinkler protection is section 8 1 which basically says to protect all spaces unless there is a specific exemption somewhere in the standard.

I have a roof with no attic space in the living room and experience radiant heat coming through the ceiling in the summer. Attics with or without storage 01. The sprinkler deflector orientations investigated were parallel to the inclined roof and parallel to the floor surface. My roofing contractor can install shingles and add more insulation on that portion of the roof but the cost is high.

Ceiling clearances applied distance from top of storage to ceiling were 10 feet and 20 feet. Some units are designed for and are safe for attic installation. The 3mm glass bulb pendent sprinklers with a k factor of 4 9 5 8 for pendent and 4 4 for horizontal sidewall permit the efficient use of residential water supplies for sprinkler coverage in residential fire protection design.

The low flow f1 res sprinklers are specially engineered. Ceiling piping cannot be used.
