LISTINGS & APPROVALS
Note: Where piping is installed above drop ceiling tiles, the piping shall be considered exposed.
Ceilings may be combustible, or non permanently installed.
• Standard Coverage Sprinklers
- Pendent sprinklers shall be FM Approved, quick response sprinklers having deflectors installed within 8 in. (203,2 mm) of the ceiling. The maximum distance between sprinklers shall not exceed 15 ft (4,6 m). The maximum ceiling height shall not exceed 10 ft (3,0 m).
- Upright sprinklers shall be FM Approved, quick response sprinklers having deflectors installed within 4 in. (101,6 mm) of the ceiling. The maximum distance between sprinklers shall not exceed 15 ft (4,6 m). The maximum distance from the ceiling to the centerline of the main run of pipe shall not exceed 7-1/2 in. (191 mm). The distance from the centerline of the sprinkler to the closest hanger shall be 3 in. (76,2 mm). The maximum ceiling height shall not exceed 10 ft (3,0 m).
- Horizontal Sidewall Sprinklers shall be FM Approved, quick response sprinklers having deflectors installed within 12 in. (304,8 mm) of the ceiling and within 6 in. (152,4 mm) of the side wall. The maximum distance between sprinklers shall not exceed 14 ft (4,3 m). The maximum ceiling height shall not exceed 10 ft (3,0 m).
- Solvent cement joints shall be made with TFP-500 or TFP-600 One Step Solvent Cement.
• Extended Coverage Sprinklers
- Pendent sprinklers shall be FM Approved, quick response sprinklers having deflectors installed within 8 in. (203,2 mm) of the ceiling. The maximum distance between sprinklers shall not exceed 20 ft (6,1 m). When the sprinklers are not on square spacings, the flow for a sprinkler should be based on the density applied over the square area calculated for the largest dimension of the sprinkler spacing. The maximum ceiling height shall not exceed 10 ft (3,0 m).
- Horizontal Sidewall Sprinklers shall be FM Approved, quick response sprinklers having deflectors installed within 12 in. (304,8 mm) of the ceiling and within 6 in. (152,4 mm) of the side wall. The maximum lateral distance between sprinklers shall not exceed 16 ft (4,9 m). The maximum ceiling height shall not exceed 10 ft (3,0 m).
- The minimum flow or pressure established for Extended Coverage Systems shall be per FM Loss Prevention Data Sheet 2-0 and 3-26.
- Solvent cement joints shall be made with TFP-500 or TFP-600 One Step Solvent Cement.
• Residential Sprinklers
- Pendent sprinklers shall be FM Approved, residential sprinklers having deflectors installed within 8 in. (203,2 mm) of the ceiling. The maximum distance between sprinklers shall not exceed 20 ft (6,1 m). The minimum required discharge from each sprinkler is to be the greater of either the approved flow rate applied over the square area calculated for the largest dimension of the sprinkler spacing or a minimum discharge of 0.1 gpm/ sq ft (4,1 mm/min) over the actual area (S x L) covered by the sprinkler. The maximum ceiling height shall not exceed 10 ft (3,0 m).
