32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- NFPA 25
- Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems; establishes frequencies and procedures for sprinklers, standpipes, pumps, and water supplies.
- Impediment
- A condition that prevents a system from performing as designed, such as a closed control valve or failed pump; requires immediate correction and notification to the AHJ.
- Deficiency
- A condition that could impair system performance but does not immediately prevent operation; it is documented and scheduled for correction per NFPA 25.
- AHJ
- Authority Having Jurisdiction; the organization or individual responsible for enforcing code requirements and approving installations, tests, and impairments.
- Record retention
- NFPA 25 generally requires inspection and test records to be kept on site for at least one year and made available to the AHJ upon request.
- Fire pump churn test
- A no-flow run of the fire pump to verify it starts and operates; churn pressure should not exceed 140% of rated pressure per NFPA 20.
- 150% flow test
- Annual fire pump test requiring the pump to deliver 150% of rated flow at not less than 65% of rated pressure, verifying the pump curve.
- Diesel pump weekly run
- Diesel fire pumps must run weekly for at least 30 minutes; record oil pressure, coolant temperature, battery voltage, and fuel level.
- Suction pressure
- The pressure at the pump suction inlet; must remain positive and adequate to prevent cavitation and meet the system demand during flow tests.
- Main drain test
- A test of the water supply by fully opening the main drain; static and residual pressures are recorded and compared to baseline values to detect obstructions.
- Spare sprinkler stock
- NFPA 13 requires at least 6 spare heads for systems up to 300 heads, 12 for 300-1000, and 24 for over 1000 heads.
- Dry pipe trip test
- Annual test of a dry pipe valve by opening the test valve to verify the valve trips and water flows within the required time.
- Control valve supervision
- Control valves must be locked open or electrically supervised; a closed valve is an impairment requiring immediate correction and AHJ notification.
- Gauge replacement
- NFPA 25 requires replacement of pressure gauges every 5 years, or when they are damaged or fail calibration checks.
- Class I standpipe
- A standpipe system with 2.5-inch outlets intended for fire department use; requires 100 psi residual pressure at the topmost outlet per NFPA 14.
- Class II standpipe
- A standpipe system with 1.5-inch hose stations intended for occupant use; typically found in older or specific occupancy types.
- Fire department connection
- An exterior connection allowing the fire department to supplement the system water supply; caps, clappers, and access must be maintained clear.
- Pressure-reducing valve
- A valve that reduces downstream pressure to a safe level; requires annual testing and 5-year full flow testing per NFPA 25.
- Smoke detector sensitivity
- Sensitivity testing is required within one year of installation and every two years thereafter, or per manufacturer instructions, to verify alarm response.
- Notification appliance test
- Annual test of horns, strobes, and speakers to verify audibility at 15 dBA above ambient or 75 dBA minimum, and visibility per design.
- Battery load test
- Annual test of emergency power batteries to verify voltage, charging current, and capacity; batteries are replaced per manufacturer intervals.
- Manual pull station test
- Annual functional test of manual fire alarm pull stations to verify alarm transmission, annunciation, and proper reset.
- Extinguisher hydrostatic test
- Pressure testing of extinguisher shells at 5 or 12 year intervals depending on type; CO2 and water every 5 years, dry chemical every 12 years.
- Class K extinguisher
- A portable extinguisher for cooking oils and fats in commercial kitchens; uses wet chemical agent and requires semiannual system inspection.
- Clean agent system
- A gaseous suppression system using agents such as FM-200 or Novec 1230; requires annual inspection of agent quantity, pressure, and nozzles.
- Wet chemical system
- A kitchen hood suppression system using wet chemical agent; requires semiannual inspection and test of fusible links and manual pull stations.
- Smoke control system
- A system of fans, dampers, and barriers designed to control smoke movement; requires annual testing of fan operation and pressure differentials.
- Stairwell pressurization
- A smoke control method maintaining positive pressure in stairwells; verify pressure differential and door opening force during annual testing.
- Emergency generator test
- Level 1 emergency power systems require monthly exercise under load for at least 30 minutes and annual full load testing per NFPA 110.
- Transfer switch test
- Verification that the automatic transfer switch transfers load to the emergency source upon loss of normal power and returns properly.
- Deficiency report
- A written report identifying the system, component, condition, and recommended corrective action; classified as impediment or deficiency per NFPA 25.
- Impairment procedure
- Notification of the AHJ, owner, and occupants when a system is out of service; interim measures such as a fire watch may be required.
