THE AH504 central warning I/O Expansion unit

The AH504 provides an additional 13 switched and 4 analogue inputs to enhance the number of inputs available in the AH500 and AH502SD warning panels. Connecting over RS232, it provides for more comprehensive alerting, particularly useful for complex aircraft types and where envelope and profile alerts require aircraft configuration data.

THE AH503 – SW45090 LED Annunciator switch

the AH503 aircraft instrument panel ANNUNCIATOR switch features daylight readable, user-customised legends with integrated snap action momentary and snap action latching options

AH500SD PROGRAMMABLE VOICE AND LEGEND ANNUNCIATOR

The AH500sd combines flight, engine and aircraft configuration data to generate voice and visual alerts.

The unit is programmed to warn off against switched, analogue and EFIS data inputs based on the switched state, value threshold or combinations of inputs to generate envelope alarms.

Envelope alerts could include oil pressure profiles, speed/ configuration envelopes, gear not down and oxygen alerts.

Data is gathered from directly connected switches and analogue inputs as well as being able to take flight and engine data from Electronic Flight Information Systems (EFIS) and Engine Monitors when available via serial buses.

Alerts are mapped to custom voice and/or sunlight readable and auto dimming captions with integration to a remote Master Caution, Master Warning and alert acknowledgement switch.

The side mounted SD card allows for easy adjustment of programming and voice files.
