If you have hardwired alarms, it's best to have the same model for all, otherwise you can get unexplained alarms going off.
Vacuum out your alarms every 6 months (or more often if you have a lot of dust or spiders). Debris building up inside them can cause them to fail or alarms to go off inexplicably. If you're remodeling or doing something that will create a lot of dust, remove the alarm temporarily.
Ionization alarms are the ones that cause a lot of nuisance alarms (the ionization only alarms are the ones that tend to be dirt-cheap). Some have started recommending photoelectric only (or mostly photoelectric only and maybe one combined photoelectric/ionization). Keep ionization alarms out of areas near the kitchen and bathrooms (moisture from bathrooms can set the alarm off).
Buying CO monitors separate from fire alarms means that if one alarm mechanism goes bad, you don't have to replace the whole thing. Unfortunately, some states now require them to be combined - but if you own your own house, you can do what you want (unless you give an inspector some reason to require you meet the regulation, like remodeling).

Our community has rated this post as helpful. If you agree, why not thank kfer
On the flip side of that, we bought all new ten- year alarms just about six years ago, and they're all doing fine.
Yup. I usually change the batteries every 2yrs
These have a manufacturer's warranty of 10-years.

but note they come with really stupid "heavy duty" batteries which shouldn't even exist anymore and will only last months, not a year
smoke detectors were another dumb thing affected by "inflation" for some inexplicable reason
Costco has 2 packs of smoke/co detectors in store for $50ish. I bought a pack yesterday
