Buzzer

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.
