The P/N 2040-1-1P Voice Alert and the P/N
2040-1-2P Voice Alert are similar to
the P/N 2040-1-1 Voice Alert and the P/N2040-1-2 Voice Alert except that
the "P" units are provided with an STC that allows the Voice
Alert to be installed in the aircraft as the primary warning in
place of the original stall and gear warning enunciator. For
example, the Cessna retractable aircraft are equipped with an
electronic dual warning unit that produces the warning sound for
both the stall and the gear position. Replacement parts for
these dual warning units are no longer available. This STC
allows the Voice Alert units to be installed in the Cessna
aircraft in place of the existing dual warning units.
Whenever the existing stall horn sounds, the
pilot will hear the instantly recognizable voice message "STALL,
STALL" from the built in speaker, and directly in his headset.
If the gear warning horn sounds, the pilot will hear the voice
message "CHECK LANDING GEAR, CHECK LANDING GEAR" alerting of the
problem.
Installation of the "P" systems is
similar to the P/N 2040-1-2 or the P/N 2040-1-1 system. The P/N
2040-1-1P system can be configured with additional warning
voices just as the P/N 2040-1-1 system can. Refer to the section
on the P/N 2040-1-1 for details.
