v. AFES, ENGINE.
The Automatic Fire Extinguisher System (AFES) is an automatic electrical system that when actuated, provides
fire extinguishing capability for the engine compartment. It consists of a TEST/ALARM panel, sensors, and
associated electrical wiring harnesses. Automatic electrical operation will sense fires and discharge halon fire
extinguishers to put out any fires. This system will not activate unless the engine TEST/ALARM panel
maintenance switch is in the horizontal power-on position. A manual discharge backup to the electrical system
enables the operator to manually discharge engine compartment fire extinguishers when the automatic system
fails to function or does not completely extinguish the fire.
