Hello,
I thought I'd close the loop on this topic.
I went ahead and installed three Kidde 10 year wirelessly interconnected
smoke/ CO detectors and so far so good.
I've been running 350 watts on 160 and 80 and that did not trigger them.
Perhaps it's time to replace the KPA500 with a KPA1500
160-6m, any mode.

Hello,
I read the thread from several weeks ago discussing the Kidde wireless
interconnected smoke detectors and the concern that they would be triggered
by RF from ham radio.
Has anyone who is running any power tried them?
A local ham running 100 watts hasn't had problems.
I have a Kidde
I have a Gen 1 Simplisafe system in our older MO outbuilding which is partially
finished to house my shack. It has been in operation for four years with no
RFI issues.
The adjacent outbuilding has a Gen 2 system that was installed last Spring – I
need to disable it and see if the grunge on
FWIW, we use a Nest Protect here (hardwired into A/C, too) and haven't had
problems with RFI. I imagine it'd be a different story if it didn't use
Wi-Fi, though.
Speaking of Wi-Fi, our Ubiquiti access point required at least four
Ethernet chokes, a third party PoE injector and CAT7 shielded cable
I have an older wired alarm system that uses serial data, and it is
indeed awful. The serial data is quite slow but it has no filtering. I
added an LC filter that works well enough to keep the RFI out of my
station, at least down to the level of what comes from my neighbors
and keeps my station

That might be the wrong thing to do. We had a number of wired
interconnected units in our house, but the one closest to the shack and
antennas started alarming every time I transmitted on 40m with more

That is probably a recipe for noise, radiated by that interconnected
wiring. The security industry has long been notorious for EMC to and
from their systems.
Heads up!
Keeping with the suggested 10 year smoke detector replacement, and wanting to
add a couple more and have them all alarm if one alarms, I bought Kidde
wireless interconnected detectors.
Well, start installation, read the manual. Under Locations To Avoid: Near
