U0O35M0 - UM26BA000000001 ENGINE AND APU FIRE EXTINGUISHING The guarded FIRE P/B switches provide FIRE indication and the means to isolate affected systems When the FIRE pushbutton is released out, the engine or APU will shut down This also arms the extinguishing system Each engine is equipped with fire bottles located in the pylon Each bottle is discharged by an associated AGENT P/BSW The P/B switches are located on the FIRE panel on the overhead For the APU, there is just one fire extinguisher bottle located in the aft fuselage forward of the APU firewall A single AGENT P/BSW The TEST buttons are used to test the respective fire detection and extinguishing system integrity MAINTENANCE COURSE -

U0O35M0 - UM26BA000000001 The A320 family aircraft are provided with a cooling system for the avionics equipment The cooling system is controlled and monitored by the Avionics Equipment Ventilation Controller (AEVC) The air is circulated through the system by a blower fan (cool air supply) working together with an extraction fan (warm air removal) The extraction airflow is downstream of the avionics equipment, so the Avionics SMOKE detector is fitted in the extraction duct and will detect smoke coming from the computers and control boxes The detector is monitored by the AEVC The AEVC signals the Flight Warning Computer to display the AVIONICS SMOKE warning in the cockpit MAINTENANCE COURSE -

U0O35M0 - UM26BA000000001 CARGO AND LAVATORY FIRE EXTINGUISHING The cargo compartment fire extinguishing agent is discharged into the FWD compartment through one nozzle (2 nozzles for A321) or into the AFT compartment using two nozzles (3 nozzles for A321) The standard system includes one extinguishing bottle located into the FWD cargo compartment (for A318 and A319 relocated to the AFT bulk cargo compartment RH side) An optional system includes two bottles The second bottle is required for extended range operations Each lavatory waste bin is protected by an automatic fire extinguishing system A small pressurized extinguisher will automatically discharge in case of a fire Fusible material in the discharge tube melts at high temperature and the pressurized agent discharges into the waste bin MAINTENANCE COURSE -
