Automatic Fire Sprinkler System
Water must be available for the standpipes and sprinklers to work. The Outside Screw & Yoke (OS&Y) valve must be open for water to flow to the sprinkler heads. Spare Sprinkler Heads are needed to replace damaged or activated heads. Having spare heads that are compatible with the system and a wrench on hand allows the system to be placed back into operation much more quickly.
All Standpipe Caps need to be in place to insure that water being pumped into the standpipe reaches the desired destination.
Gauges on Wet or Dry Systems must show pressure. If no pressure is indicated, a problem may exist with the system.
Caps on the Fire Department Connection must be in place to keep small animals and debris out of the sprinkler/standpipe system.
In order for water from the sprinkler head to adequately cover the fire area, there must be at least 18 inches of clearance between the sprinkler head and materials stored under it.
