How often are sprinklers systems required to be tested?
The Life Safety Code adopted and enforced by the Office of the State Fire Marshal makes reference to another NFPA standard to define the testing and maintenance requirements for sprinkler systems. Specifically, NFPA Standard #25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems is referenced. NFPA 25 establishes testing and maintenance schedules for various system components (i.e., valves, alarm devices, sprinklers heads, etc.). There is not one singular answer to the question of how often sprinkler systems or their components must be tested. NFPA 25 sets varying requirements based upon the type of sprinkler system and types of components and appurtenances that are present. By statute, those who inspect and maintain automatic sprinkler systems (other than weekly or monthly inspection and testing of control valves and gauges) must be OSFM-licensed fire sprinkler contractors.
