An Ideal Routine Sprinkler Inspection Plan

of commercial fire sprinkler systems

How Often Should A Fire Sprinkler System be Inspected?

The lives of building occupants and the protection of your assets rely on proper operation of a well designed, properly maintained fire protection system. The automatic fire sprinkler system acts as the first line of defense in the event of a fire emergency.

It’s necessary to perform not only a single yearly inspection, but to have a solid inspection plan to coincide with a building maintenance routine, keeping a record of all fire sprinkler inspections and tests.



Sprinkler System Inspection Schedule

Weekly or Monthly Inspections

Inspect gauges in dry, pre-action, and deluge systems as often as once a week. Wet pipe system gauges can go a month between inspections.

Quarterly Inspections

Every three months, inspect the water flow alarm devices, valve supervisory alarm devices, supervisory signal devices, control valves, and hydraulic nameplates.

Sprinkler System Testing Schedule

Quarterly Sprinkler Inspection

Fire Sprinkler Mechanical Devices are to be subject to quarterly inspections. For more information on Quarterly Inspection requirements or definitions, please refer to NFPA 25.

Semi-annual Sprinkler Inspections

Vane and pressure switch type devices must me tested every six months. Be sure to keep solid records as your system inspections and testing progresses.

Annual Sprinkler Inspections

Full testing and tagging are performed. A technician is to perform physical checks on all parts of your fire sprinkler system. Water flow tests, fire pump tests, antifreeze concentration tests (if applicable), alarm tests, and trip tests of dry pipe, deluge, and pre-action valves, will be performed to ensure compliance with NFPA 25.

Fire Sprinkler Inspections (5yr)

Sprinklers exposed to extra-high temperatures and harsh environments, along with gauges on all sprinkler system types, should be tested or replaced.

Fire Sprinkler Inspections (10yr)

Dry sprinklers should be tested or replaced. Rapid-response sprinklers should be tested after 20 years in use and every 10 years preceding. Standard response sprinklers should be tested after 50 years in use and in 10 year intervals preceding.
