Buzzer
SUBTASK 25-62-11-450-001
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.

1)
Fabricate a bracket suitable for supporting the buzzer. See Figure 20.
NOTE:
Refer to the aircraft manufacturer’s written instructions or AC 43.13
-2, as applicable,
for approved bracket fabrication and installation methods.

1)
