Fire Sprinkler Protection
I'm installing a sprinkler system that the design calls for 160' 0f 11/4" pipe over 10 hotel units. The problem is that the attic space is unconditioned. There will be 10 drops off of the main to the rooms below. Some of the units will be unoccupied in the winter months. The only thing I can come up with is to use Temp. sensitive heat tape then wrap in insulation. Does anyone have any other ideas.
