(a) the ceiling ridge is horizontal;
(b) the compartment openings to adjoining spaces have minimum lintel depths of 8 inches (203,2 mm) below the lowest sprinkler;
(c) any adjacent sprinklers in the direction of the ceiling ridge are to be in a row which runs parallel to the ridge,
and the sprinklers are to be spaced a minimum of 8 feet apart;
. (d) the sprinklers are Installed with Deflector Arms perpendicular to the ceiling ndge; and,
- (e) the sprinklers shown in Figures F -1 through F -8 are located in a plane which is perpendicular to the ceiling ridge, .
and the ceiling angles are within the specified range.
