- · Fire pump — weekly no-flow test (diesel), monthly churn test
- · Water flow alarm devices
- · Supervisory signal devices (tamper switches)
- · Valve supervisory switches
- · Pressure gauges on dry/pre-action systems
- · Low-point drains on dry-pipe systems
- · All sprinkler heads — visual inspection for corrosion, damage, or obstruction
- · Gauges — calibration check
- · Hydraulic nameplates — legibility
- · Hangers and seismic bracing
- · Waterflow alarm test
- · Main drain test
- · Anti-freeze loop systems
- · Standpipe systems — hose connections, pressure, flow
- · Fire pump full-flow test
- · Dry-pipe valve trip test under full flow conditions
- · Deluge and pre-action valve trip test
- · Check valves — internal inspection
- · Internal pipe inspection — obstruction investigation
- · Sprinkler heads in harsh environments replaced or tested
- · Gauge replacement or recalibration
- · Dry-pipe system — internal corrosion assessment

Source: NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. Frequencies shown are minimums under the current edition. Non-water-based systems (FM-200, CO₂, clean agent, kitchen hood) are governed by their respective NFPA standards (NFPA 12, 17, 2001, etc.) and may have different inspection schedules. Always confirm applicable requirements with your AHJ.
Hiring Guidance
What to Ask Before Hiring in Alabama
"Are you licensed in Alabama?"
Ask for their license number and verify it directly with Alabama State Fire Marshal's Office before signing any contract.
"Do you follow the current NFPA 25 edition?"
A qualified contractor should be able to confirm which edition of NFPA 25 they follow and provide a written inspection report after each visit.
"What systems do you service?"
Not all contractors are qualified for every system type. Confirm they have experience with your specific system — wet pipe, dry pipe, kitchen hood, clean agent, etc.
"Do you carry liability insurance?"
Ask for a certificate of insurance. Work on fire suppression systems carries liability; an uninsured contractor puts your property at risk.
