Last year, we re-wired the entire house (power, phone, cable tv and
data) and installed new Kidde KN-COSM18 hardwired detectors,
including one in the shack. No issues, even when the SB-220 is used.

I would also be interested to hear about others' experience with hardwired
smoke/fire/CO2 detectors. Building codes now require new construction to
have hardwired/interconnected smoke detectors. I read lots of horror
stories about hardwired smoke detectors on the web. All of the ionization
type smoke detectors and CO2 detectors in my house have no RFI/EMI
problems, but both of the photoelectric fire detectors chirp when I run
QRO. I have to pull out the battery when I run QRO. That wouldn't be so
easy with a hardwired detector, so I'd like to know how to avoid problems.
Will ferrite beads on the leads be sufficient? Are there brands that are
known to be less problematic?
