We have 6 detectors, 10 foot ceilings and as stated previously they are hard wired as well as the battery back up. Great fun if I need to take down the five to get the serial numbers.
I do wonder why we have 6 detectors AND there are none in the garage-the place most likely to catch fire.

I was the original poster:
According to what I've read and posts from fellow villagers, the carbon monoxide sensors do not last as long as smoke detectors. It seems the carbon monoxide has a clock built in. It is not sensing failure but time that has passed. The time starts running when you install the battery.
Our unit is a FIRST ALERT SC9120B and we replaced it with the current model which we purchased at ACE roughly 37.00-it is marked with a 7 year warranty. We chose to replace with the same brand so we did not need to replace the mount already screwed to the wall.
The old defective unit is a simple twist lock to remove. The new unit comes with the necessary connector. Rather than messing with wire nuts, part of the reason we decide to buy the same brand was so we could use the existing connector. The plug is very tight. Make sure you have the pins properly aligned before you force anything.
TIME-took longer to dig my ladder out of the garage then to actually install it.
