[RFI] Smoke Detectors Beeping

[Stanley Zawrotny]

Standalone smoke detectors are fine in mobile homes and other small installations where one or two will do the job. We have a two family home (my daughter has the other wing) and we have 9 units. We would want to be informed if aa fire broke out on her side of the house.

“Trying” another brand is a shakey solution when replacing the system would cost a couple of grand with no guarantee of return if it didn’t work.

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.
