Get Testing, Inspection, And Maintenance Frequencies For Fire

Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. NFPA 25 is the baseline for inspection, testing, and maintenance of water-based fire protection systems. Compliance helps maximize system integrity to avoid failure and ensure fast, effective response in a fire emergency.

The annual test frequency is a minimum requirement, NFPA 25 permits more frequent testing if desired.

In section 25.2 it states that all fire alarm systems in commercial premises need to be tested weekly to ensure that there has not been any major failure, and that the fire alarm system is in working order.

NFPA 25 dictates this fire sprinkler testing schedule: Quarterly: In order to be as effective as possible, fire sprinkler mechanical devices should be tested quarterly. Semiannually: Every six months, vane and pressure switch type devices must be tested. Annually: Full testing and tagging should be performed annually.

NFPA 25 requires an internal inspection of fire sprinkler system piping every five years. This is to be conducted to inspect for the “presence of foreign organic and inorganic material.” Foreign materials can cause obstructions to pipe and sprinklers.

Hard-wired (including low voltage) smoke detectors must be sensitivity tested in ance with NFPA 72(10), Sec. 14.4. 5.3. o Detector sensitivity must be checked within 1 year after installation and every other year thereafter.

Newly installed sprinkler systems must be hydrostatically tested to check for leaks at a pressure of at least 200 psi (14 bar) for a period of at least two hours.

ing to NFPA 25, the property owner or designated representative is accountable for the fire protection system's overall maintenance. During monthly inspection, the on-site fire protection person should examine the pipe system gauges, ensure water pressure maintenance, and inspect the alarm valves.
