What exactly seems "not right"? The velocity or projectiles have nothing to do with it. Piping will not even hold up.
I feel your case hinges on required or not. FM is calling for it so.. R/ Matt Matthew J.

Something about little glass bulbs or solder links in an area that has high velocity projectiles, seems not right. Everything in each alley (including the separation walls) are non-combustible. The only thing combustible at the end of the range is shredded rubber used to absorb the impact after the target. The rubber is treated with flame retardant and replaced every three months. Each alley has a series of baffles below the roof that are at a 45 degree angle for sound. The designer of the facility has done many of these without sprinklers in this area of the building. He has even shot tracers to see how the flame retardant hold up and the flame goes out is less than 20 seconds. A fire marshal is saying to sprinkler everything. If you have any insight, I am listening closely. *Jay Stough* NICET IV LAYOUT NICET III ITM _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
