Aviation's Panel Mount Avionics Installation Leader

The CO Guardian Carbon Monoxide (CO) detector is designed especially for the experimental and homebuilt aircraft market. A compact and lightweight unit meant to use as little panel space as possible (or remote mounted in small area behind the panel), the 353P combines highly accurate CO detection for the cockpit as well as cabin pressure warning and the ability to display on an external unit (see hardware list). This CO detection unit is perfect for builders and pilots looking for protection from the dangers of carbon monoxide in their experimental, homebuilt, or non-certified aircraft and integration with an existing PFD, MFD, or engine monitor system.

The sensitive onboard CO sensor alarms when carbon monoxide levels measure greater than 50 parts-per-million (PPM). A loud 85db aural warning will sound and an amber warning LED will flash when CO measures 50 to 99 PPM over a 3-5 minute span. An aural warning and a red LED flashing warning will trigger when levels climb above 99 PPM immediately when detected.

The built-in pressure sensor indicates altitude warnings at 10,000 feet, 12,500 feet, and 14,000 feet as a reminder to the pilot that supplemental oxygen should be used. These warnings are displayed on an optional annunciator light.

The included RS-232 serial connection allows added CO level reporting and alerts to be displayed on a variety of Primary Flight Display (PFD), Multi-Function Display (MFD), and engine monitor products. Please refer to the approved product list below.

The compact and lightweight CO Guardian 353P-101 will fit into a small 2.25" x 1.5" instrument position. The 353P-201 will fit into a small 2.25" x 1.5" position in a remote location using the included mounting bracket. Installation is very simple and takes only 2-4 hours on average.
