Fire Sprinkler vs. Fire Alarm Inspections

The fire alarms and fire sprinklers in your building need to be inspected and tested in accordance with NFPA guidelines and local codes. With different regulations for inspection and testing frequencies for each type of system, it can be hard to keep track of when your systems need service. Inspection intervals will vary based on the AHJ (authority having jurisdiction) and the type of system you have.

Inspections vs. Testing of Fire Protection Systems

Inspections of fire protection systems include visual checks that the system looks to be in the proper condition. Testing of systems involves more in-depth physical checks that your systems are functioning correctly.

Fire Sprinkler Testing & Inspection Frequencies

Inspections and testing of fire sprinkler systems may be performed weekly, monthly, quarterly, semi-annually, and annually.

Weekly

Every week, inspections of gauges in dry, pre-action, and deluge sprinkler systems should be performed.

Monthly

Inspections of gauges in wet pipe sprinkler systems should occur on a monthly basis.

Quarterly

Inspections of fire department connections, water flow alarm devices, valve supervisory alarm devices, supervisory signal devices, control valves, and hydraulic nameplates should be performed every quarter. Testing of fire sprinkler mechanical devices should occur on a quarterly basis.

Semi-Annually

Semi-annually, vane and pressure switch type devices must be tested.

Annually

Annually, hangar and seismic bracing, pipes and fittings, information signage, and spare sprinklers should be inspected.  Every year, a full test and tagging and physical checks on all parts of the fire sprinkler system should be performed, including:

  • Water flow test
  • Fire pump test
  • Antifreeze concentration test (if applicable)
  • Alarm tests
  • Trip tests of dry, deluge and pre-action valves

Every 3 Years

If you have a dry or pre-action sprinkler system, testing leak rates need to be tested every 3 years.

Every 5 Years

Every 5 years, you need to get an internal inspection of your sprinkler piping performed and test the gauges. Sprinklers exposed to extra high temperatures or harsh environments should be tested or replaced every 5 years.

After 15 Years, Then Every 10 Years

               Dry sprinklers should be tested or replaced after 15 years and then every 10 years after that.

After 20 Years, Then Every 10 Years

Fast response sprinklers should be tested after 20 years and then every 10 years after that.

After 50 Years, Then Every 10 Years

Standard response sprinklers should be tested after 50 years, then every 10 years after that.

Fire Alarm Inspection & Testing Frequencies

Inspections of your fire alarm systems should occur weekly, monthly, semi-annually, and annually.

Weekly

Every week, you should inspect control equipment including fuses, LEDs, power supply, and check for trouble signals on your fire alarm system.

Monthly

Inspections of batteries for your fire alarm system should be performed monthly.

Semi-Annually

On a semi-annual basis, testing of the functionality of flow switches, tamper switches, and backup batteries should be performed. Visual inspections of initiation and notification devices should occur semi-annually.

Annually

Full testing and inspection of your fire alarm system should be performed every year, including:

  • Horn/strobe testing and inspection.
  • Inspection and testing of pull stations, detectors, and flow switches.
  • Control panel testing and inspection.
  • Battery and backup power supply panel testing and inspection.
  • Testing of voice evacuation equipment.
  • Send signals to monitoring center to test communication path.
