FM APPROVALS Project ID: 3046888 APPROVAL OF HILTI CABLE TRANSIT SYSTEM CFS-T FOR USE IN WALL AND FLOOR ASSEMBLIES RATED UP TO AND INCLUDING 2 HOURS for HILTI, INC. 5400 SOUTH 122ND EAST AVENUE TULSA, OK 74146 I INTRODUCTION 1.1 Hilti, Inc. submitted their Cable Transit System CFS-T devices for examination to determine if they meet the FM Approvals requirements of the Standard listed below when installed in fire rated gypsum walls and concrete floor or wall assemblies.
FM APPROVALS Project ID: 3046888 II MATERIAL DESCRIPTIONS 2.1 The Hilti Cable Transit System, Model CFS-T, is a system used to firestop openings in rated floors and walls. The units are designed principally for the shipping and offshore industries. The units are either rectangular or round in shape. The devices examined in the program consist principally of a galvanized steel frame, elastomeric sealing modules, steel anchor and a steel compression device with adjusting nut.
FM APPROVALS Project ID: 3046888 3.2 Approval Standard 4990 requires that all through penetrations shall be subjected to a fire resistance test conducted in accordance with ASTM E814 (08) "Standard Method for Fire Tests of Through-Penetrations Fire Stops” followed by a hose stream test conducted in accordance with ASTM E2226 (07), “Practice for Application of Hose Stream”. An hourly rating will be assigned based on the time period for which it successfully met the performance criteria. 3.
FM APPROVALS Project ID: 3046888 IV TEST ASSEMBLIES 4.1 This test program consisted of two (2) wall assemblies and one (1) floor assembly. The wall assemblies incorporated two (2) openings while the floor assembly incorporated three (3) openings. A description of the test assembly is given below. 4.1.1 Test Specimen No. 1 (Ref. TBTL 908a) consisted of a 2 hour fire rated gypsum wall with steel studs. The wall contained two (2) separate openings as described below.
FM APPROVALS Project ID: 3046888 4.1.3 Test Specimen No. 3 (Ref. TBTL 909a) consisted of a 2 hour fire rated gypsum wall with steel studs. The test specimen was identical to Test Specimen No. 1. When installed within a wall, the units are not symmetrical. One side of the wall contains the unit while the other side of the wall contains mineral wool. Since it could not be determined which side would be more critical, separate fire tests had to be conducted exposing each side of the wall to the fire.

Two hour fire rated gypsum wall assembly consisting of steel channel studs. Gypsum Board. Min 5/8 in. (16 mm) thick x 4 ft (1.2 m) wide gypsum wallboard applied to each side of the wall.
FM APPROVALS 3046888 Page 2 of 2 3.FIRESTOP SYSTEM. The firestop system shall consist of the following: Circular Firestop Devices – Circular firestop device for use in preformed openings. The firestop device shall be inserted into the framed opening and friction fit on one side of the wall assembly. Each device consists of a seal plug unit with compression device and single/multi-diameter elastomeric sealing modules.
FM APPROVALS 3046888 Appendix C Page 1 of 2 FIRE STOP DESIGN 668 F Rating – 2 HR T Rating – ¾ HR TFM Rating – ¾ HR and 1 HR (see item 3) 1. FLOOR OR WALL ASSEMBLY. Min 4-1/2 in. (114 mm) thick lightweight or normal weight concrete floor or wall, or minimum 8 in. (200 mm) thick concrete block wall. Max size of opening is 11.8 in. x 11.0 in. (300 mm x 280 mm). 2. FIRESTOP SYSTEM.
FM APPROVALS 3046888 Page 2 of 2 modules shall be left in place or “blank” (solid) sealing modules shall be used. During the installation of the elastomeric sealing modules, thin steel anchor plates shall be used to separate the rows of sealing modules and to retain the sealing modules within the steel frame. After installation of the modules, the bolts of the compression unit are tightened to form an effective seal around the penetrants and insert modules.
