Mike Lamb Posted June 30, 2008 Report Share Posted June 30, 2008 Image Insert: 19.33 KB I believe these are covers for sprinkler heads. Can anyone fill me in as to how they operate? Should they be painted? Link to comment Share on other sites More sharing options...
Darren Posted June 30, 2008 Report Share Posted June 30, 2008 Mike; There is a 'melt-link' on the cover. When it gets to a certain temperature (don't quote this, usually about 95 degrees I think), the link melts and the cover falls down. Usually, it'll state right on the cover "DO NOT PAINT" Link to comment Share on other sites More sharing options...
Mike Lamb Posted July 1, 2008 Author Report Share Posted July 1, 2008 Thanks, Darren. You are right on. I did some searching and came up with this for anyone interested. http://www.rouchtec.com/TD2003R.pdf DON'T PAINT! Link to comment Share on other sites More sharing options...
