TM 8-2350-267-10 CREW AUTOMATIC FIRE EXTINGUISHING SYSTEM (AFES) COMPONENTS - Continued Optical Fire Standard Control Sensing Assembly Electronic Amplifier STANDARD CONTROL ELECTRONIC AMPLIFIER (SCEA) Processes input signals from OFSA units when hydrocarbon fuel fire is detected. If the fire is large, the S(XA lights the FIRE AMRM lamp on the crew compadment T/A panel and activates the two fire extinguishers on vehicles 1 thru 344 (three fire extinguishers on vehicles 345 and above). If the large fire continues, or a second large fire occurs, the SCEA activates the re- maining  crew  compartment  fire  extinguishers. If the OFSAdetects a small fuel fire, the SCEA signals the T/A panel, and the red FIRE ALARM lamp on the T/A panel flickers. The crew uses a portable fire extinguisher or activates the red guarded MANUAL ELECTRIC DISCHARGE toggle switch on the T/A panel to put out the small fire. The SCEA contains BITE which internally tests the unit for normal operation. A LED on the T/A panel lights to indicate a fault in the SCEA unit. 4-15
