[RFI] Smoke Detectors Beeping

[Randy Standke]

Another possible solution to RF sensitive smoke detectors are the newer 10 year battery smoke detectors now available.  Even if you had wired smoke detectors.  Just install the new detectors in the same location to cover the electrical box.  This avoids the problem with susceptibility to the RF on the wiring since there is no wiring connected to these detectors.  I also understand that the sensors degrade over time.  With these 10 year detectors you toss the whole thing in 10 years.  I recently volunteered with the Red Cross to install smoke detectors in a mobile home community.  We only used the 10 year battery models.  Some homes had really old wired detectors.  The advice was if they are more than 10 years old replace them.  So we did, right over the old electrical box.  I have two from Kidde in my house.  1500 Watts into roof mounted antennas doesn't bother them.

Poor design is almost always the problem when it’s the only thing with a problem.
I have old co2 detectors that beeped.
Replaced with quality brand an now all is ok.
