Abstract
An apparatus for extinguishing fires in enclosures having an air ramp with an automatic trap door. When the trap door is tripped, the air flow is reduced. Fires can be extinguished through the reduced air flow. The air ramp includes a center section having an upwardly ramped center area, a trap door which is moveably attached to the center area and a front section which is connected to the center section. The front section allows the air ramp to be mounted in an enclosure.
