Wouldn't feeding the fire with fresh air make it more intense? I also read that the flight deck has a halon portable fire extinguisher, any reason why inaccessible areas of aircraft don't have inbuilt halon extinguishers?
StormyKnight:
That may be true for fires fueled by combustible materials, however the EE bay contains mainly electronics cards, wiring, and aluminium racks and equipment cases. These items 'burn'
primarily due to electric current providing the input heat and not combustibles contained within.
Generally, EE bay 'fires' are limited to smoke events where no amount of oxygen deprivation will quench them because they are typically self sustaining until power is removed.
Note on detection on the A320 series (and most aircraft types) - EE/Avionics bay uses an ionization type detector while some aircraft's lavs use photo type detectors - photo detectors being of the type that can be fooled by condensation fog.
