w. AFES, CREW.
The Automatic Fire ExnguisherSystem (AFES) is an automatic electrical system that when actuated, provides
fire extinguishing capability for the crew compartment. It consists of a TEST/ALARM panel, sensors, halon fire
extinguishers, 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 crew 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.
