CREW AFES COMPONENTS (continued)
The crew AFES activates automatically when one of four optical fire sensing assemblies (OFSAs) detects hydrocarbon
fuel fires. Crew AFES components are described on pages 4-11 through 4-15.
Crew Test and Alarm (TIA) Panel
The T/A panel provides status lights and switches and contains the electronic circuitry necessary to monitor the crew
AFES.
The T/A panel interfaces with the standard control electronic amplifier (SCEA) and the OFSA.
The crew AFES has built-in test equipment (BITE), which automatically monitors the status of components and allows
crew members to test the components for normal operation.
A red-guarded, two-position MANUAL DISCHARGE toggle switch permits the crew to manually discharge crew
compartment fire extinguishers.
