Tell my wife to get her ass home. I'm hungry.

Good food for thought here folks. I'll have to investigate the 10 year versions.

So I have a 1966 garrison colonial. I could easily retrofit linked detectors into the 2nd floor.

Do people just use low voltage phone or 3-wire copper? What do I run to link these? I suppose the package will tell me.

Anyone have preferred make/model?

(Also, I should mention how cool it was that my SF search actually yielded an active thread on the topic I was looking for. How unique was that experience?)

I do this for a living (electrician), can help out for sure. Going to bed shortly. Shoot me a email (in profile) I'll give you the options.

I usually suggest hardwired for top floor (attic access) wireless for middle/basement. Preferred is hardwired for the whole house if economically viable.

The time changes?
 

well, time changes in "most" of the country twice a year....

battery changes twice yearly, when daylight savings time kicks in/out. The 10 year battery thing is ok, just remember the sensors themselves can and do fail before that battery will fail....we usually see a life expectancy of average 7 years out of the sensors themselves as a general rule.
Carbon Monoxide is very close in weight compared to air....CO is .98 and air is 1.0 which means CO will dissipate fairly evenly in any given space....so put your CO detection wherever the hell you want it.

side note coming from a 23 year veteran firefighter: a very high percentage of fatal fires i've been directly involved with had non working or absent smoke detectors.....very few fatals that had them and they were working properly....they are cheap life insurance

I bought the 9V lithium batteries some years ago, so I only change them every 5 years.

They also have audio sensors that are programed to sense when all the occupants of the house have entered the deepest moment of sleep based on sleep sounds gathered over a six month period.

apparently mine have these same options. I'm fumbling around changing batteries in smoke and co detectors, crawl back in bed; sob if they don't start that shit again. Check house for fire, throw detectors in pool.
