The hourly F and FH Ratings of the firestop system are dependent upon the hourly rating of the wall in which it is installed.

2. Firestop Device* — The firestop device consists of a steel plate sandwich construction with three (16" device size) or four (24" device size) circular opening ports which are each nom 4 in. (102 mm) diam. The firestop device is intended to be oriented vertically or horizontally and mounted to the face of the opening on both sides of wall. The 16" and 24" firestop devices when oriented horizontally are attached to the 16 in.

(406 mm) and 24 in. (610 mm), respectively, center to center spaced wall studs at each side of opening, over the gypsum board. As an option, up to two devices may be installed adjacent to each other with a nom 13/16 in. (2 cm) overlap to protect larger sized openings (see Item 1B, double device). As an option, single and double 16" and 24" gang plates may be attached directly against the studs prior to installation of the gypsum board layers. When 16" gang plate is installed horizontally in 24" stud cavity, attachment of plate to wall studs is optional. As an option, two devices may be installed end to end in adjacent stud cavities, over the gypsum board layers or directly attached to the wall studs when installed in accordance with the Hilti Installation Instructions and min one layer of gypsum board each side of wall is continuous across the two stud cavities. Each device shall be secured to gypsum board with min No. 10 by 1-1/2 in. (38 mm) steel drywall screws through prepunched holes around periphery of steel device plates; min three (16" gang plate) or four (24" gang plate) screws are used at each long dimension and three screws at each end. When device is secured direct to studs prior to installation of gypsum board layers, the fasteners along each long dimension of opening are spaced max 2-1/2 in. (64 mm) from corners and max 6 in. (152 mm) on center unless otherwise noted in Hilti Installation Instructions. Min screw length is 3/4 in. (19 mm) where device is secured direct to studs and at the overlapping plate to plate joint for double devices. The device shall be installed in accordance with the accompanying installation instructions. When the hourly rating of the wall assembly is 1 hr, blank gang plates (no cables) may be installed vertically or horizontally for single gang plate openings only, and double gang plates are limited to installation horizontally with fasteners at ends of plates penetrating into wall studs.
