About this file
This document is a fire protection system inspections, testing, and maintenance checklist based on NFPA 25 standards, provided by USA Fire Protection as a reference guide for facility owners and managers.
The checklist outlines a comprehensive preventive maintenance schedule for fire sprinkler and suppression systems across multiple time intervals: weekly inspections of control valves, temperature verification, and pressure gauges; monthly examinations of valve exteriors and air compressor conditions; quarterly visualizations of fire department connections and testing of relief valves; semi-annual testing of waterflow switches and nitrogen concentration verification; and annual operational tests of hose valves, control valves, partial trip tests of deluge systems, and lubrication of valve stems. Extended intervals include three-year operational testing of Class II hose valves and full flow trip tests; five-year internal inspections of pipe, deluge valves, and strainers, plus gauge replacement and hydrostatic testing; twenty-year sample testing of dry sprinkler heads and ESFR/CMSA units; twenty-five-year testing of fast-response sprinkler heads; and fifty and seventy-five-year testing protocols for all sprinkler heads with specified retesting intervals. The document includes a disclaimer that the checklist serves as a guide only and does not guarantee code compliance, recommending consultation with a fire and life safety professional and USA Fire Protection for jurisdiction-specific compliance assurance.
