Inspection & Maintenance Protocols for Fire Fighting Systems

Inspection & Maintenance Protocols for Fire Fighting Systems

A fire fighting system sits idle for 99.9% of its lifecycle. However, when an emergency strikes, it must operate with 100% reliability. Under NFPA 20 guidelines, property managers and facility engineers bear full legal liability for executing scheduled inspection, testing, and maintenance (ITM).

Mandatory Testing Schedules Under NFPA 20

To prevent corrosion, valve seizing, or control failure, your maintenance partner must follow strict operational routines:

Weekly Protocols

• Diesel Fire Pump Engine Run: 30-minute no-flow test run to verify battery cranking voltages, oil pressure, and cooling jacket temperature.

• Electric Fire Pump Run: 10-minute test run to verify automatic start logic and packing gland lubrication drips.

• Gauge Readings: Verify normal static pressure across system risers and jockey pump controllers.

Annual Certified Performance Testing

• Fire Pump Flow Test: Hook up test header hoses to draw 50%, 100%, and 150% of rated GPM capacity. Plotting the hydraulic curve ensures internal impeller wear hasn't degraded performance below design standards.

• Full Flow Drain Test: Opening the main drain to measure static and residual pressure drops, verifying no internal pipe blockages or closed street valves.

• Clean Agent Concentration Checks: Weighing gas cylinders and inspecting room integrity seals to ensure design gas density is maintained for required hold times.
