Guardian Avionics Aero 452-101 CO Detector

The AERO 452-101 panel mounted Carbon Monoxide (CO) detector is a TSO Certified unit designed especially for use in FAA certified aircraft. A compact and lightweight unit meant to use as little panel space as possible, the 452-101 combines highly accurate TSO certified 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 owners and pilots looking for protection from the dangers of carbon monoxide in their 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 85 dB 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 AERO 452-101 will fit into a small 2.25 in by 1.5 in instrument position and weighs only 3.5 oz. Installation is very simple and takes only 2-4 hours on average. The 452-101 accommodates a connection to an external annunciator light (sold separately) to add an additional level of safety when the unit is out of view.
