SECTION IV - SYSTEM DESIGN UL EX. 3470 ULC CEx747 Page 4-52 REV. 1 10-1-02 MANUAL PULL STATION REQUIREMENTS A remote manual pull station allows the R-102 system to be man- ually operated at some point distant from the regulated release assembly. The pull station should be installed at a maximum height of 60 in. (152 cm) and located in the path of exit. The pull station is the only source of manual actuation of the regulated release assembly. The totalleng1h of the cable used for each manual pull station with- in a system must not exceed 150 ft. (46 m). The maximum number of pulley elbows that may be used per pull station is 20. One pulley tee, Part No. 427929, is allowed per system. The maximum length of cable from the AllTOMAN to a pull station is 150 ft. (45.7 m) with a maximum of 20 pulley elbows used per side of the tee. As the tee is located far1her from the AUTOMAN, the 150 ft. (45.7 m) maximum must be observed but as pulley elbows are placed between the AUTOMAN and the tee, they must be deducted from the available pulley ebows (20) allowed on each side. Example: If 10 pulley elbows are placed between the AUTOMAN and the pulley tee, the maximum available pulley elbows left for ~ use on each side of the tee is 10 per side. See Figure 94 for three I different examples. (Note: Both must be gas valves or both must . be pull stations. Mixing is not allowed.) TEE CLOSE TO AUTOMAN (EXAMPLE) PULLEY TEE 12 IN.

The system works both mechanically and pneumatically by use of an air cylinder located inside the regulated release assembly. Upon actuation of the fire suppression system, a pneumatically-operated air cylinder assem- bly will mechanically close the gas shut-off vaMl. The totalleng1h of the cable for each mechanical gas valve must not exceed 150 ft. (46 m). The maximum number of pulley elbows that may be used is 20 for each valve. One pulley tee (Part No. 427929) is allowed per system. The maximum leng1h of cable from the AUTOMAN to a gas valve is 150 ft. (45.7 m) with a maximum of 20 pulley elbows used per side of the tee. As the tee is located farther from the NJTOMAN, the 150 ft. (45.7 m) maximum must be observed but as pulley elbows are placed between the AUTOMAN and the tee, they must be deduct- ed from the available pulley elbows (20) allowed on each side. Example: If 10 pulley elbows are placed between the AUTOMAN and the pulley tee, the maximum available puley elbows left for ~ use on each side of the tee is 10 per side.
