whats the testing procedures for fire sprinkler system?

Q:

A: Well, that question is a little vague. The testing proceedures for a new system are a little more in depth that the required testing and maintenance issues for existing systems. (Pressure testing of new piping for a 24 hour period prior to comissioning for example on new systems, vs. an annual flow test a the inspector's valve on the same system after it is in service, for one example.) The type of sprinkler system also changes the testing requirements. Wet Systems (those with water in the lines at all times) require different testing proceedures that say a Dry-System (where air in the lines is kept under a supervised pressure), the presence of antifreeze loops, drum drips, pre-action controls, etc., etc. can also have a big impact on what is required. (Not all sprinkler systems are the same!) The NPFA standards offer the nationally accepted guidelines in the United States for the testing of new and existing systems. See NFPA 13 for new systems, and NFPA 25 for existing systems. You can order the guides directly from NFPA, but for a cheaper option, check with your local fire prevention office, local sprinkler service company, or maybe even your local librbary for a copy of the testing sections of these standards. If you have a more specific question, re-post and I'll give it my best shot.
