How old are yours...?! (story below)
CO sensors tend to be good for about 5 years. I'm sure there is some annual drift but they're expected to stay reasonably dependable that long, monitoring a much higher range than scuba air, and then it's better to replace with current technology than try to replace & calibrate a sensor in an appliance that old. I got a couple for my daughter's house a year or two ago even tho she didn't think their all-electric home needed one; I wanted them in my grandkids' rooms close to the attached garage! I may not have written the date on the back so when I check, I'll get the serial numbers so I can find out when they were made and mark them.
Then it finally occurred to me that their bedroom and that of our boy from Berlin is close to the fireplace! Duh, those things put out a lot of CO! I got them 2 more and a new one for my bedroom, moving one to the kitchen, throwing away an old one. Hint: used ones are sold on Ebay, but consider them worthless! I actually made that mistake once.
I went for the First Alert Plug-In With Battery Backup (CO) Carbon Monoxide Detector and this model even includes a "end of alarm life timer" reminder alto I am going to mark the purchase dates on these. I got them at the local Chinese Outlet for $26 each; Target, K-mart and many other stores carry them if local stock is low.
I doubt this family had any really as so many don't, which kills 400-500/year in the US, injuring thousands more. The dad had complained that they "were sick and nauseated which are symptoms of carbon monoxide poisoning," but they probably shrugged that off as seasonal illnesses. Sad loss...!

This happened in my good friend's town...she's a SB Member actually. She called me tonight and asked if I had CO Monitors...I don't. I'm going to buy some this week!
