14.0 UNIT FAILURE INDICATION:
A failure of the CO Sensor, Temperature Sensor, or the Micro-controller will result in the
following failure indications:
•
The remote Amber light will flash at an approximate rate of one flash each four (4)
seconds until the failure is cleared or power is removed from the unit. NOTE: SEE
MFG manual if the fault data is integrated with the MFG MFD for fault analysis.
In case of a failure indication, attempt to clear the failure condition by resetting the CO
Detector. Should the failure condition continue, remove the CO Detector power by pulling
the CO Detector circuit breaker.
15.0 RS-232 DATA BUSS OPTION
The RS-232 Data Buss option is currently available on numerous MFD units like the
Garmin GNS480 and Garmin G1000. The RS-232 data buss output will couple CO
Detector status information to electronic display systems with RS-232 input capability.
The unit transmits CO Level, Cabin Temperature, Cabin pressure and is remotely reset
able via RS232.
See Multi-Function display manufacturers Installation Manual for interface guidance.
