Some Warnings Should Be Impossible to Ignore.
Cockpits are noisy places. Engines, radios, intercom audio, and ANR headsets all compete for your attention.
When something important happens, a tiny beep may not be enough.
The Radiant 110 dB Aviation Annunciator produces an extraordinarily powerful audible warning from a compact package only 31.5 mm in diameter.
At 12 Vdc, sound output is rated at a minimum 110 dB at 10 cm, with typical output of 115 dB.
This is not a polite notification.
It is an alarm.
The 110 dB annunciator makes sure the warning gets your attention.
Use It as a Gear Warning
Building or flying a retractable-gear experimental aircraft?
The annunciator can provide the audible warning for a custom gear-position or gear-unsafe system.
Experimental aircraft applications only.
Build Your Own Master Warning
The annunciator can also be driven by suitable aircraft warning or control circuitry for applications such as:
- Canopy or door not latched
- Gear warning
- Critical engine warning
- Low oil pressure
- Low fuel pressure
- Electrical-system warning
- Engine-monitor alarm output
- Custom EFIS warning output
The annunciator supplies the sound; your aircraft system supplies the warning logic.
