A.
Location
CAUTION: PLACING THE BUZZER IN THE COCKPIT IS NOT RECOMMENDED DUE TO THE POTENTIAL
FOR DISTRACTION. THE BUZZER PRODUCES A LOUD, SIREN-TYPE SOUND WHEN THE
ELT IS ACTIVATED. SINCE THE BUZZER OPERATES IN TANDEM WITH THE COCKPIT LED,
IT WOULD ONLY SERVE AS A REDUNDANT WARNING INDICATOR IN THE COCKPIT.
1)
Select a suitable location for the buzzer.
NOTE:
The buzzer may be located anywhere in the aircraft; however, the recommended location is
near the ELT, as the buzzer is loud enough to be heard outside the aircraft when the
engine(s) is not running. When the engine(s) is running, the LED on the cockpit remote
switch assembly will warn the pilot the ELT is active.

approved bracket fabrication and installation methods.

2)
Attach the bracket to the airframe such that the buzzer is adequately supported and does not show any
significant evidence of distorting the airframe skin.
3)

a)
Remove the panel mounting nut and insert the buzzer in the bracket.
NOTE: Alternatively, the buzzer may be attached to the support using the mounting holes
on the buzzer body and appropriate hardware.
