New Carbon Monoxide Detector Parts for G1000 Systems

ATA: 31-20	Models: 172, 182, 206, 350, 400
The Co Guardian Model 452 Carbon Monoxide Detector P/N 452-201-006 has been superseded by a new P/N 452-201-010 Carbon Monoxide Detector in the Cessna Service Parts and Program (CSP&P). Visible differences between the old and new units are the wiring harness attached to the old part has been incorporated internally into the new unit. This modification causes the new unit to be noticeably a little longer in length. No additional electrical harness is required and the existing wiring in the airplane will have enough length to make the connection to the new detector. Airplanes configured with Co Guardian Model 452 Carbon Monoxide Detectors P/Ns 452-201-003 and 452-201-004, have also been superseded by the new P/N 452-201-010 part. However, operators should be aware that due to differences in the aircraft wiring an additional P/N 452-201-099 electrical harness is required. The new harness is shown in the photograph below:
