If the packaging materials are class 3 commodities, they could design to FM.

What about using Single Interlock Pre-action. We got a bid for a "Quell" pre-action dry system with detection that is crazy expensive with a 2500 gpm fire pump. Good city water is adequate for an ESFR system without a pump from a 20" water main. What is the poor reliability aspect Concern?

You could use heat detection in lieu of smoke detection depending on environmental conditions. Heat tracing a complete system is a disaster waiting to happen IMHO. Also the Heat trace system must be electronically supervised to insure operability. So he will need a fire alarm system for it to connect to. Craig L.

[EXTERNAL] I have a client that is renovating an uninsulated 30,000 SF shed warehouse. He does not want to heat the building. Dry system requirements for solid piled storage over 25Ft high in 35 Ft. high building are not available. I am pushing for an ESFR wet system in a heated building. Rather than heating an uninsulated building owner suggests we heat the sprinkler pipe with heat cable and 1" insulation. This method is in 13. Tyco has a system to apply heating cable to branch lines and cross mains. In over 50 years I have never seen or heard of heat tracing being done. I think it is a mistake due to reliability and cost There must be reasons this heating method is not being installed on a sprinkler system. What arguments can I use to avoid this method of keeping a wet grid system from freezing.
