Vehicles 1 thru 344 were manufactured with an engine T/A panel
housing and LED access cover. Vehicles 345 and above were
manufactured with an engine T/A panel without an LED access
cover. Both of these engine T/A panels are interchangeable.
In addition to the indicators on the crew T/A panel, a Remote Status Indicator (RSI) (5),
which is a component of the engine AFES, is mounted on the crew compartment ceiling to
alert crewmen to an engine fire. An ENGINE FIRE lamp (6) at this unit flashes when an
engine overheat or small fire condition exists. The ENGINE FIRE lamp also lights when-
ever a large engine fire exists. During lamp test in vehicles with an engine T/A panel with
an LED acess cover, this lamp will not light. In vehicles with an engine T/A panel without
an LED acess cover, this lamp will light. During normal operation, this lamp will not be lit.
Ventilation blower turns to exhaust mode when Halon discharges. Open vent after extin-
