(1.1 m), 3 ft 6 in. Baffles shall be arranged to protect the actuating elements. This prompted the submittal of a proposal for the 2002 edition whereby Table 8.9.5.1.3 (the section number changed in 1999 and again 2002) would have an allowance to have obstructions closer to the sprinkler (as allowed for standard spray). The TY-FRB Sidewall Sprinkler delivers effective, affordable defense against fire in light or ordinary-temperature applications. The distance from sprinklers to the end walls shall not exceed one-half of the allowable distance permitted between sprinklers as indicated in Table 10.3.3.2.1. (1.1 m) to less than 4 ft (1.2 m), 4 ft (1.2 m) to less than 4 ft 6 in. The appropriate interpretation is that obstructions could be closer than 4 ft, but could be no closer than 4 ft when they extended below the plane of the deflector. Leave a comment.
