As you can see, the two detectors are very similar. The main difference is the CO detection range, with the 553-101-001 detecting CO levels up to 1000 ppm, while the 551-101-002 only detects CO levels up to 999 ppm. The 553-101-001 also has a cabin pressure warning feature, which the 551-101-002 does not have. Otherwise, the two detectors have the same features and specifications.

Ultimately, the best detector for you will depend on your individual needs and budget. If you need a detector that can detect CO levels up to 1000 ppm, then the 553-101-001 is the better option. If you don't need that extra range and are looking for a more affordable option, then the 551-101-002 is a good choice.

Guardian Avionics 551-101-002 Problems and Solutions

The Guardian Avionics 551-101-002 is a panel-mounted digital carbon monoxide (CO) detector that is designed for use in both FAA certified aircraft and experimental aircraft. It is a TSO-certified unit that is known for its accurate and fast CO detection.

The most common issue with the Guardian Avionics 551-101-002 is a faulty CO sensor. This can happen after a period of time, as the sensor becomes less accurate. To check if the CO sensor is faulty, you can perform the following steps:

1. Power on the unit.
2. The unit should perform a self-test. If the self-test fails, the CO sensor is faulty and needs to be replaced.
3. If the self-test passes, the unit should display the current CO level. If the CO level is consistently above 75 ppm, the CO sensor may be faulty.

If you suspect that the CO sensor is faulty, you should contact Guardian Avionics or an authorized dealer for replacement.

Here are some other common issues and solutions for the Guardian Avionics 551-101-002:

• The unit is not turning on. Make sure that the unit is properly plugged in and that the battery is not dead. If the unit still does not turn on, contact Guardian Avionics or an authorized dealer for troubleshooting.
• The unit is not displaying the correct CO level. Make sure that the unit is properly calibrated. If the unit is still not displaying the correct CO level, contact Guardian Avionics or an authorized dealer for troubleshooting.
• The unit is beeping. The unit may be beeping due to a high CO level. If the CO level is above 75 ppm, the unit will sound an alarm. If the CO level is above 300 ppm, the unit will sound an alarm and the display will flash.

If you experience any of these issues, you should consult the Guardian Avionics 551-101-002 owner's manual for further troubleshooting instructions. You can also contact Guardian Avionics or an authorized dealer for assistance.
