Annunciators

The Voice Annunciator (AV-17) can provide from one to seventeen verbal warnings through your headset:  Oil Pressure and Temperature, Fuel Level and Pressure, RPM, Manifold Pressure, Altitude and Timer, Cylinder Head Temperature, Exhaust Gas Temperature, Turbine Inlet Temperature, Engine Analyzer, Bus Voltage, Gyro Vacuum, Landing Gear, Air Speed, Oil Pressure, Fuel Level, Timer, Chime Only (no voice) and Bus Voltage. The AV-17 ends the need to constantly scan instruments. It also eliminates concern about missing an alarm at a critical moment. The instant a monitored alarm occurs, the Voice Annunciator will chime in the headset and a pleasant female voice will announce a phrase, such as: "Check Oil Pressure," or "Check Altitude," etc.

The AV-l7’s voice alarm in the headset provides an instant and clear understanding of what’s going on in the cockpit without the hassle of having to scan instruments, decipher functions, interpret readings or translate numerous bongs, buzzes or beeps.

The AV-17 connects to the headset through the Audio Panel or Intercom or it may be connected directly to the headset. The AV-17 receives most of its warning signals from any one or more of Electronics International’s instruments which feature a warning light. However, other alarm inputs can be received from any warning device that drives a horn or light. It is not necessary to activate all seventeen of the AV-17’s warnings. A "Check Bus Voltage" warning is built into each AV-17. Further voice alarms can be activated as Electronics International instruments are added to the panel.

The AV-17 is compact. A 4.1 x 2.6 x 1.7" Control Box tie wraps under the instrument panel. Also, there is a small 1" x 1" Control Panel that mounts on the aircraft instrument panel. The Control Panel allows you to turn the Voice Annunciator on or off. Also, it allows you to acknowledge and thereby deactivate any active alarm for either 1 minute or 10 minutes. The AV-17 voice alarms are activated by pulling the appropriate control line to ground (0 volts).

The AVI-1 module allows a positive voltage to activate ONE AV-17 control line.  The AVI-1 is not necessary when connection to an E.I. Instrument.
