I have put sprinklers in several shooting ranges (Government made me do it). They were all double interlock preaction systems with piping run above the steel roof/ceiling of the range. They all used concealed type sprinklers. One of the ranges utilized a saw tooth ceiling/roof to protect the heads. Two of the systems have been hit and put into trouble (including the saw tooth one - hit by a ricochet). Luckily no water has been released. I know one system that has been hit several times and the building has turned the system off.

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
