The smoke detectors we have here are wired into the security system - no
replaceable batteries - except for one which is standalone in the
bedroom and was required to be added by the inspector when we built the
house even with the whole house system in place. No RFI problems observed.
We do know the whole house detectors work - the security folks have
called those times when we let the toast burn in the oven! I had to
have one in the shop building moved because it was right over the
workbench and would alarm any time I was doing fine power sanding - even
though I had a dust collector running.
Thanks for the info on the 10 year units. We have replaced the
standalone one 3 times in 17 years, so we are about right on a 5 year
replacement schedule.

For what it’s worth, the American Red Cross is recommending installation of
units that have 10-year lithium ion batteries which are sealed and not
replaceable. History has shown that kids tend to remove the batteries for
their toys and games.
