Unveiling The Guardian Avionics 451-201: Exploring Specifications, Manuals, Pros And Cons, And Common Problems
Guardian Avionics 451-201 Information
The Guardian Avionics 451-201 is a remote-mounted carbon monoxide (CO) detector designed for use in FAA-certified Part 23 aircraft and Part 27 and 29 rotorcraft. It is a small, lightweight unit that can be installed behind the instrument panel to take up minimal space. The 451-201 features a sensitive CO sensor that alarms when carbon monoxide levels reach 50 parts per million (PPM) or higher. An aural warning with varying pitch sounds at 85 decibels (dB), and an amber LED flashes when CO levels are between 50 and 99 PPM. A red LED flashes and the aural warning sounds continuously when CO levels reach 100 PPM or higher.
The 451-201 is powered by 14/28 VDC and has a built-in temperature compensating circuit to ensure accurate CO readings in a wide range of ambient temperatures (0°F to 110°F). It is also shielded to prevent electromagnetic interference (EMI) with aircraft systems.
The 451-201 comes with a test/reset button and an external mounting bracket. It is also available with a crimp connector kit for easy installation.
