Guardian Avionics 451-101: Full Specifications, Comparisons, Manuals, Pros And Cons, Problems, And Where To Buy
Guardian Avionics 451-101 Information
The Guardian Avionics 451-101 is a panel-mounted carbon monoxide (CO) detector designed for FAA-certified Part 23 aircraft and Part 27 and 29 rotorcraft. It is a compact and lightweight unit that uses a sensitive onboard CO sensor to alarm when carbon monoxide levels measure greater than 50 parts-per-million (PPM).
Introduction
Carbon monoxide is a colorless, odorless gas that can be deadly if inhaled in high concentrations. It is produced by incomplete combustion of fuels, such as gasoline, propane, and natural gas. In an aircraft, CO can be produced by a variety of sources, including the engine, exhaust system, and auxiliary power unit.
The Guardian Avionics 451-101 helps to protect pilots and passengers from the dangers of CO poisoning by providing early warning of elevated CO levels. The unit has two levels of alarms:
- Amber alarm: This alarm sounds when CO levels measure 50 to 99 PPM over a 3-5 minute span.
- Red alarm: This alarm sounds when CO levels climb above 99 PPM immediately when detected.
The 451-101 is also equipped with an external annunciator light, which can be mounted in a visible location in the cockpit to provide an additional level of safety.

Comparison
The Guardian Avionics 451-101 is the smallest and lightest of the three products. It is also the least expensive. However, it has the lowest sensitivity of the three products, meaning that it may not detect CO as early as the other two products.
The Midtronics 7004 is slightly larger and heavier than the Guardian Avionics 451-101, but it has a higher sensitivity. It is also more expensive.
The Atlantic International 4800 is the largest and heaviest of the three products. It also has the highest sensitivity. However, it is the most expensive.
Conclusion
The best product for you will depend on your individual needs and budget. If you are looking for the smallest and lightest CO detector, the Guardian Avionics 451-101 is a good option. If you are looking for a CO detector with the highest sensitivity, the Atlantic International 4800 is a good option. If you are looking for a CO detector that is both sensitive and affordable, the Midtronics 7004 is a good option.
Guardian Avionics 451-101 Pros/Cons and My Thought
The Guardian Avionics 451-101 is a panel-mounted carbon monoxide (CO) detector designed for FAA certified Part 23 aircraft and Part 27 and 29 rotorcraft. It is a compact and lightweight unit that uses a sensitive onboard CO sensor to alarm when carbon monoxide levels measure greater than 50 parts-per-million (PPM).
Pros:
- The 451-101 is FAA-approved for installation in certified aircraft, making it a legal and safe way to protect yourself from the dangers of carbon monoxide poisoning.
- It is a very compact and lightweight unit, taking up very little panel space.
- The sensitive onboard CO sensor can detect CO levels as low as 50 PPM, giving you plenty of warning time before CO levels reach dangerous levels.
- The 451-101 has two separate alarm levels: an amber LED and audible alarm for CO levels between 50 and 99 PPM, and a red LED and audible alarm for CO levels above 99 PPM.
- The 451-101 can be connected to an external annunciator light, which can be helpful if the unit is installed in a location where it is not easily visible.
Cons:
- The 451-101 does not have a battery backup, so if the aircraft's electrical system fails, the unit will not be able to detect CO.
- The 451-101 is not a continuous CO monitor, so it will not detect CO levels that are rising slowly over time.
- The 451-101 is not a replacement for proper ventilation, and it should not be relied on as the sole means of protection from carbon monoxide poisoning.
User Reviews:
- Positive: "This CO detector is a great way to add an extra layer of safety to my aircraft. It is small, lightweight, and easy to install. The alarm levels are clear and audible, and I have peace of mind knowing that I will be alerted if CO levels start to rise."
- Negative: "I wish the 451-101 had a battery backup. I also wish it was a continuous CO monitor, so that I could be alerted to rising CO levels even if they are not immediately dangerous."
My Thoughts:
Overall, I think the Guardian Avionics 451-101 is a great option for pilots who are looking for a compact and lightweight CO detector to install in their aircraft. It is FAA-approved, has a sensitive CO sensor, and two separate alarm levels. However, it does not have a battery backup or continuous CO monitoring, so it is not a replacement for proper ventilation.
If you are looking for a CO detector that will provide you with the most comprehensive protection, I would recommend a continuous CO monitor with a battery backup. However, if you are looking for a small, lightweight, and affordable CO detector that is FAA-approved, the Guardian Avionics 451-101 is a great option.
