Fire Sprinkler Systems

XL-Trace is designed to maintain fire suppression system standpipes, supply piping, mains, 
feeders, branch lines and sprinklers at 40°F (4°C) in areas subject to freezing .

Refer to the 

Fire Sprinkler System Freeze Protection Design Guide

 (H58489) for detailed in-

structions to design XL-Trace heating cable circuits to freeze protect aboveground or buried 
supply pipe, feeders, mains standpipes, branch lines and sprinklers .

Approvals

The 2007 edition of nFPA 13 (Standard for the Installation of Sprinkler Systems) allows List-
ed electrical heat tracing to freeze protect fire suppression systems including supply lines, 
standpipes and branch lines containing sprinklers . XL-Trace is c-CSA-us Certified for use on 
fire suppression systms under CSA C22 .2 no . 130-03 for Canada and Ieee 515 .1-2005 for 
the US . The system covered in this manual includes supply lines, standpipes, branch lines 
and sprinkler heads .
XL-Trace systems are also UL and ULC Listed for freeze-protecting sprinkler supply lines, 
standpipes up to 20 inches in diameter and branch lines not containing sprinklers .
