Possible failures and corrective measures for wet pipe sprinkler systems and fire detection systems

Table 7-1 lists general problems that may arise during the testing of equipment and systems along with possible troubleshooting techniques. For all problems, consult equipment and component manuals for troubleshooting directions. Check fuses/lights/breakers/etc., for continuity, check equipment calibration and settings, check for clogged strainers, check for closed manual shutoff valves, check for improperly adjusted valves and equipment and look for faulty equipment and connections.

1. Repair of wet pipe sprinkler system and fire detection system. It is recommended that adjustments and corrections to wet pipe sprinkler and fire detection systems be done by licensed and bonded fire sprinkler companies and fire detection companies.
2. Fire code compliance. It is imperative that the NFPA Fire Code standards and manufacturer’s recommendations relative to each suppression, detection and alarm system be consulted before any operation is performed on any of these systems.
