Guardian Avionics 451-101 Problems and Solutions

The Guardian Avionics 451-101 is a panel-mounted aviation carbon monoxide detector that is authorized for Part 23, 27, and 29 aircraft/rotorcraft under the Non-Required Safety Enhancing Equipment (NORSEE) authorization. It is a small, lightweight unit that is easy to install and requires only a "Minor Alteration" logbook entry by an IA.

The 451-101 has two levels of alarms:

• Amber alarm: This alarm sounds when carbon monoxide levels measure 50 to 99 PPM over a 3-5 minute span.
• Red alarm: This alarm sounds when carbon monoxide levels climb above 99 PPM immediately when detected.

If the 451-101 sounds an alarm, there are a few steps you can take to troubleshoot the issue:

1. Check the battery. The 451-101 is powered by a 3V lithium battery. If the battery is low, the unit may not be able to provide accurate readings.
2. Check the sensor. The 451-101 has a carbon monoxide sensor that can become dirty or blocked over time. If the sensor is dirty, it may not be able to detect carbon monoxide properly.
3. Check the wiring. The 451-101 is wired to the aircraft's electrical system. If the wiring is damaged, it may cause the unit to malfunction.

If you have checked the battery, sensor, and wiring and the 451-101 is still sounding an alarm, you should contact Guardian Avionics for further assistance.

Here are some additional tips for troubleshooting the 451-101:

• Check the installation instructions. The installation instructions for the 451-101 are very clear and should be followed carefully. If the unit is not installed correctly, it may not work properly.
• Use a calibrated CO meter. If you are still having trouble troubleshooting the 451-101, you can use a calibrated CO meter to measure the carbon monoxide levels in the aircraft. This will help you to determine if the unit is actually detecting carbon monoxide.

The 451-101 is a reliable unit that should provide many years of service. However, if you do experience problems with the unit, the troubleshooting steps above should help you to identify and resolve the issue.
