Overview

The AERO 553 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.

Please note, Aircraft Spruce Australia's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce Australia assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Does it also act as clock w/ timing functions?

Per the manufacturer: Yes the CO guardian has a clock.

Q: How does one test and calibrate the CO detector? Can a bump test be performed? Is there instructions for test & calibration?

The unit comes calibrated from the manufacturer and can only be calibrated by the manufacturer. The installation/operators manual is included with this unit which outlines testing although, the only user executable test to be performed is the power-on self test.

Q: Does the CO sensor wear out like the cheap $3 sticker detectors found on most planes?

The CO2 sensor wears out after 7 years from date of install.

Q: What is the TSO Number that the AERO-553 follow?

Per the manufacturer the number is TSO-C48.

Q: After 7 years can the co detector be serviced or is replacement the only option?

They can be recalibrated through Guardian directly.

Q: Is there an installation manual that can be posted on the website for reference prior to purchasing the unit?

We have added the installation diagram to the web page.

Q: It states in the description that it can be used on Certified Aircraft yet no 8130 available from the manufacturer. A customer is asking how a part advertised on sale for Certified Aircraft could be installed without 8130?

It can be installed because the unit has a TSO certification from the FAA. Typically a 337 form and field approvals are required for this type of installation.

Q: After reviewing the wiring diagram it appears this unit doesnt have an audible alarm. The wiring diagram just sends a signal to the audio panel. Is that correct? No audible alarm.

The AERO 553 does have an audible alarm out of pin 8 that does provide an alert if there is an alarm. You should also here a tone when the unit is turned on.
