Your commercial building’s automatic fire sprinkler system is the first line of defense when fire breaks out. Fire sprinklers can control a fire and keep it small while protecting occupants from harm and saving your business. So, how do you know your sprinkler systems will work when needed?
When you follow the required fire sprinkler system inspections, testing, and maintenance schedules set by the National Fire Protection Association (NFPA) and your local Authorities Having Jurisdiction (AHJ), you ensure your system operates as it was designed to minimize the risk of damage and loss of life should there ever be a fire.
The death rate per 1,000 reported fires was 87% lower in properties with sprinklers than in properties with no automatic extinguishing system (AES). – NFPA Report, U.S. Experience with Sprinklers, 2010-2014
How Often Do I Need to Have Sprinkler System Inspections?
The adopted codes require all commercial entities and nonprofit organizations follow NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. Each local AHJ may also have additional testing and inspection requirements. Be sure to check with your area’s fire marshal for those codes.
The NFPA25 Standard requires fire sprinkler system inspections on this schedule:
- Weekly: dry, pre-action, deluge systems gauges, control valves.
- Monthly: wet pipe system gauges, alarm valves.
- Quarterly: control valves, hydraulic nameplates.
- Annually: building, hanger/seismic bracing, pipes/fittings, sprinkler heads, information signage, spare sprinkler heads, pre-action/deluge valves, dry pipe valves, backflow prevention assemblies.
- Every 5 years: internal inspection of sprinkler piping, obstructions, check valves.
Weekly, Monthly, Annual Fire Sprinkler Inspections
A designated staff member who is trained in the proper NFPA25 Standards and local code compliance may perform weekly inspections. This person should check for normal air and water pressure on the dry, pre-action, and deluge systems gauges. He or she will also make sure control valves are not leaking or locked, that they are sealed and open.
Monthly, your on-site fire protection person should look at the wet pipe systems gauges, confirm water pressure is maintained and that there are no signs of physical damage. Alarm valves should also be inspected for physical issues.
The quarterly, annual, and every five- and ten-year inspections, along with system maintenance, testing, and repairs must be performed by a licensed fire protection technician who retains comprehensive records for a minimum of one year and has the ability to produce these maintenance records when requested.
In 97% of fires with operating sprinklers, five or fewer heads operated. Reported sprinkler failures (660 per year) were twice as common as reported fires in which sprinklers were ineffective and did not control the fire. – NFPA Report, U.S. Experience with Sprinklers, 2010-2014
When to Perform Fire Sprinkler Maintenance & Testing
A test is a more involved physical check to make sure the fire sprinkler system not only looks like it’s functioning, but actually works as it should. Routine maintenance and repair are critical to keep your fire sprinklers in good working condition.
Fire Sprinkler System Testing Timeline
Quarterly, semi-annual, and annual fire sprinkler system testing and tagging must be performed and documented by a licensed technician in accordance with NFPA25 and your AHJ. Inspection tags for fire sprinkler systems must be current.
- Quarterly: mechanical alarm devices, main drain.
- Semi-annually: vane and pressure switch type devices.
- Annually: control valves, pre-action/deluge valves, dry pipe valves, backflow prevention assemblies.
- Every 5 years: sprinklers exposed to extra-high temperatures and harsh environments, along with gauges on all sprinkler system types.
- Every 10 years: dry sprinklers; sprinklers with fast-response elements that have been in service for 20+ years.
- Other: test standard-response sprinklers after 50 years; then in 10-year intervals.
Fire Sprinkler System Maintenance Timeline
Fire sprinkler system maintenance is a vital step in the inspection and testing process that should never be skipped. In fact, without proper maintenance, your fire sprinkler system may appear in working order and test okay once a year, but without lubrication, tightening of loose bolts, cleaning, and clearing lines, your fire sprinklers may experience a shortened life span and may not work during a fire.
- As needed: repair and maintain parts that appear questionable during visual inspections/testing.
- Annually: lubricate control valves, clean interior of the pre-action/deluge valve and dry pipe valves; repair/replace parts as needed.
- Other: Examine systems for internal obstructions where conditions exist that could cause obstructed piping. Correct if it has not been corrected or the condition is one that could result in future obstruction of piping despite previous flushing procedures.
