The Aero 452 Carbon Monoxide Detector is designed to detect, measure, and provide both a visual and aural alert to the crew of piston engine type aircraft before the level of carbon monoxide (CO) reaches a critical level. It is the first TSO-certified Carbon Monoxide detector for use in General Aviation.

The installation consists of a single carbon monoxide detector indicator operating on aircraft DC power. The aircraft supplied power and aircraft wiring is protected by a 2 ampere, resetable, trip free, type circuit breaker. The Aero 452 is installed in the existing aircraft instrument panel within view and reach of the pilot.

The unit contains a Test/Reset button, an aural alarm buzzer, an amber LED ALERT annunciator, and a green LED STATUS annunciator.

The carbon monoxide alarm level is calibrated to provide both an aural and visual alert within 5 minutes or less whenever the carbon monoxide level reaches 50 parts per million (PPM) by volume or above per TSO C48A. The warning time is shortened at higher levels of CO concentrations and becomes approximately instant should the carbon monoxide level reach 400 parts per million by volume (PPM) or above.

In case of a carbon monoxide alert, the pilot can acknowledge the alert and silence the aural warning while keeping the visual alert until the carbon monoxide level is again reduced below the alert level. The indicator is automatically reset when the CO level drops below 50 PPM. There is a three-minute delay at startup for sensor to stabilize before the unit will sense CO.
