I installed a CO guardian CO and cabin pressure alarm.  I think the number is a 352P.  I added an extra amber bright light.  I’m confident the CO detector works because if you start your engine between hangers or on a windy day between hangers it alarms.  The altitude alarm works good too but sometimes it false alarms on climb out but only around 9,000 ft. up at 26K or 27K (where I fly normally) its never given me problems.  I’ve got 500 hours on it so far.  Well worth the investment and very small.  You can buy the panel mount or hide the remote mount out of the way.  See link.

Subject: CO and a pressurized cabin -- is there a worry?

Hi All,

Since I'm new to the IV-P, I am wondering what the level of worry is of carbon monoxide getting into a pressurized cabin.  I know with my old Cherokee or Mooney, I always had CO detectors (either electronic of that little cardboard thing that changes colour)... but with the pressurized cabin, I would think there may be less chance, perhaps close to no chance, of it getting into the cabin.

Can someone please shed some light on this for me?

Thanks,
