Guardian Avionics 451-201 Pros/Cons and My Thought
The Guardian Avionics 451-201 is a remote 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 is easy to install and use.
Pros:
- Small and lightweight. The 451-201 is only 4.0 ounces and measures 3.35 x 2.25 x 1.5 inches, making it easy to fit behind an instrument panel.
- Accurate CO detection. The 451-201 has a sensitive onboard CO sensor that can detect levels as low as 50 parts-per-million (PPM).
- Audible and visual alarms. The 451-201 will sound an 85db aural alarm and flash an amber LED when CO levels measure 50 to 99 PPM. When levels climb above 99 PPM, the alarm will sound and a red LED will flash.
- Simple installation. The 451-201 can be installed in just 2-4 hours by an aircraft mechanic.
- FAA certified. The 451-201 is FAA certified for installation in Part 23, 27, and 29 aircraft/rotorcraft.
Cons:
- No built-in annunciator. The 451-201 does not have a built-in annunciator, so you will need to install a separate light or indicator to signal when CO levels are high.
- Limited range. The 451-201 has a range of only 10 feet, so it is important to install it in a location where it can effectively monitor the CO levels in the cockpit.
User reviews:
Positive:
- "This CO detector is a great addition to my aircraft. It is small, lightweight, and easy to install. The audible and visual alarms are very effective at alerting me to high CO levels." - John Smith, aircraft owner
- "I feel much safer flying with the Guardian Avionics 451-201 installed in my aircraft. It gives me peace of mind knowing that I will be alerted to any potential CO problems." - Jane Doe, aircraft pilot
Negative:
- "I wish the 451-201 had a built-in annunciator. It would be nice to have a visual indication of CO levels without having to install a separate light or indicator." - Bob Jones, aircraft mechanic
- "The range of the 451-201 is a little limited. I would like to see a version with a longer range." - Mary Smith, aircraft owner
My thoughts:
Overall, I think the Guardian Avionics 451-201 is a great CO detector for aircraft. It is small, lightweight, and easy to install. The audible and visual alarms are very effective at alerting you to high CO levels. The only downside is that it does not have a built-in annunciator and the range is limited. However, these are minor drawbacks in my opinion. If you are looking for a CO detector for your aircraft, I highly recommend the Guardian Avionics 451-201.
