    In my two previous blogs, we first discussed wet sprinkler systems (Wet), the most basic and most common fire system type followed by dry sprinkler systems (Dry), which are a bit more complicated.  Ratcheting up another level, in this last edition on sprinkler systems, let’s take a look together at preaction and deluge systems.  These can be complex and variable, so we’ll operate at the 30,000 ft level.

    In my previous blog , I discussed the most basic and most common fire system type: wet sprinkler systems. The possible failure areas discussed with wet systems will also apply to dry sprinkler systems (control valves closed, obstructions, issues in the system, installation, or deficiencies with inspection, testing, and maintenance). Dry systems are even more prone to obstructions than wet systems, so close attention should be paid to that possibility. (more…)

    After a major fire, it is necessary to investigate the fire sprinkler system to see if and why it malfunctioned. Wet sprinkler systems are the most common and least complex fire sprinkler systems in use. The following are major items addressed in an investigation involving a wet system.

    If available, drawings of the supply piping and sprinkler system are helpful. If these are not available, a sketch of the system will be made. Requests will also be made for inspection, testing, and maintenance documentation as well as fire alarm logs.

    The top reason that fire sprinkler systems do not function correctly during a fire is (more…)
