AERO 452-201-012 Remote Mount CO Detector for Dynon SkyView HDX
$549.00 – $573.99
Remote Mounted TSO Certified CO Detector with Cabin Pressure Warning
Remote Mounted TSO Certified CO Detector with Cabin Pressure Warning
The CO Guardian 452-201-012 remote mounted Carbon Monoxide (CO) detector is designed especially for the Dynon SkyView HDX line of Certified aircraft displays. A compact and lightweight unit meant to use as little space behind the panel as possible, the 452-201-012 combines highly accurate CO detection for the cockpit and the ability to display on an external Dynon unit. 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.
The 452-201-012 is specifically designed to integrate with and report on the Dynon SkyView HDX line of PFD and MFD displays for Certified aircraft. Both alerts and CO levels can be displayed.
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 compact and lightweight CO Guardian 452-201-012 will fit behind the panel as a remote installation and weighs only 4,0 oz. Installation is very simple and takes only 2-4 hours on average. The 452-201-012 accommodates a connection to an external annunciator light (sold separately) to add an additional level of safety when the unit is out of view.

FAA Certification
When installed in accordance with this installation manual and the limitations, the installation of our TSO Approved models 452/454/455/551 and 553 is unlikely to have an appreciable effect on the weight, balance, structural strength, reliability, operational characteristics, or other characteristics affecting the airworthiness of the aircraft, and should therefore be eligible for installation as a minor alteration.
Please see the Instructions of continued Airworthiness for each model for limitations (available on downloads page). Most customers have been able to install these as Minor installation per AC 23.1309-IE and FAR 23.109. You must seek proper guidance prior to installation from you local FAA FISDO for clarification.
FAA Advisory Circular on CO
The above FAA circular provides information on the potential dangers of Carbon Monoxide contamination from faulty engine exhaust systems or cabin heaters of the exhaust gas heat exchange type. It also discusses means of detection and procedures to follow when contamination is suspected.
FAA Requirements for CO in Aircraft during Certification
FAR. 23.831 Ventilation in Aircraft
(a) Each passenger and crew compartment must be suitably ventilated. Carbon monoxide concentration may not exceed one part in 20,000 parts of air (50 PPM).
All Panel mounted units are designed to alarm within 5 minutes if CO is between 50 PPM and 75 PPM to meet the requirements of TSO C48.
AERO-152WD Warning Levels shown below. Note: (252,352’s, 353’s,452’s and 552 all alarm with 5 minutes if CO is above 50PPM).
Caution – This product is intended to be used in aircraft enclosed cabins. Because of its super-sensitivity, it’s not designed to be in compliance with UL2034, OSHA, and other industry standards.
National Transportation Safety Board Recommends CO Detectors to be installed in all General Aviation Aircraft.
FAA CERTIFICATION / STC
When installed in accordance with this installation manual and the limitations that follow, the installation of the model 452 is unlikely to have an appreciable effect on the weight, balance, structural strength, reliability, operational characteristics, or other characteristics affecting the airworthiness of the aircraft, and should therefore be eligible for installation as a minor alteration.
Model AERO 452 has TSO certification and is STC approved for installation on certified aircraft. Customers have three options depending on their relationship with their local FAA FISDO office (you must seek proper guidance prior to installation). 1) Install it as minor log book entry since the unit is TSO approved as non essential equipment. 2) Install it using FAA Form 337 as minor alternation. 3) Install it per supplied STC on a Cessna 172.
However, no approval exists for the other panel-mount models of CO Guardian (models AERO 252, 352’s, 353’s, 551 and 553). Acceptance for the installation and use of as a non-essential equipment (per AC 23-15, paragraph V, pg. 28), must be sought through your local FBO and the appropriate offices of the Federal Aviation Administration or other certifying agency.
