Aviation facilities are unique structures, with unique fire protection requirements. Most often, large aircraft hangars will require fire pumps to provide the required pressures. NFPA 409, Standard on Aircraft Hangars provides the guidance and requirements for fire pumps in aircraft hangars.
- All pump installations are to meet the requirements of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection.
- A minimum of 2 fire pumps is required.
- Pumps are required to auto-start. This can be via pressure drop, or signal from detection control panel.
- If the pressure drop method for pump starts is used, a jockey pump is required to be installed.
- Fire pumps must be stopped manually. They cannot be set to 'auto-stop'.
- An audible 'pump running' alarm is required. This alarm is to be transmitted to a constantly attended location.
