Panel CO Detector with Digital Clock / Timer & Cabin Pressure Warning
Panel CO Detector with Digital Clock / Timer & Cabin Pressure Warning
The AERO 553-101-001 Multi-Function Carbon Monoxide (CO) detector is a panel mounted TSO Certified unit designed especially for use in both FAA certified aircraft and experimental aircraft. Designed to fit in, and replace a standard 2.25” (2 1/4”) standard instrument panel clock, the AERO 553 gives you a full set of clock, timer, temperature, cabin and density altitude functions along with highly accurate and extremely fast CO detection and PPM readings within the cockpit on an easy-to-read LCD display.
Features Include:
- Carbon Monoxide Detection: The AERO 553 will detect and display true CO levels from 30ppm to 999ppm for real-time tracking of Carbon Monoxide in the cockpit. The 553 will alarm if the CO level exceeds 50-70 ppm for more than 5 minutes or will provide an instant alarm if CO spikes above 300ppm within one minute.
- Clock Function: Displays Local Time and Zulu Time in a 24 hour format.
- Flight Timer: Flight Timer starts automatically on take off when 150 ft above runway level. It can also be started manually.
- Stop Watch: Stop watch function allows you to time any segment of your flight.
- Inside / Outside Air Temp: Keeps track of inside and outside air temperature in both Fahrenheit and Celsius. (Requires AERO 553-500 OAT Probe)
- Battery Voltage: Receive an instant alert when battery voltage drops / rises above pre-set levels for 14 / 28 V systems.
- Cabin Altitude: Monitors cabin altitude and sounds an alert when you climb above 10,000 ft , 12,500 ft, and above 14,000 ft. This alert provides the pilot a reminder to equip supplemental oxygen as required.
- Density Altitude: The density altitude is indicated based on the absolute pressure and OAT. (Requires AERO 553-500 OAT Probe)
- RS-232 Output: Indications/Alerts may be configured to display on select 3rd party avionics products (contact Guardian Avionics for updated list)
- Remote Annunciator Light: A Remote Annunciator Light may be installed and connected for CO alert and Altitude alert in a visible position when the AERO 553 is mounted out of plain sight.

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.
