OT: Kidde smoke detectors; Any follow up on RFI frm wireless models?

[VA3LX]

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 wired interconnection smoke detector system that I trigger
with > 250 watts. Numerous attempts with ferrite chokes and bypass
capacitors haven't resolved it.

I have a fairly new Kidde wired system (battery / AC) with a total of 10
sensors on 3 levels.

No RF issues with KPA/KAT500 at full power on any band 160-6m, any mode.

Hello Lyn and Thanks.

I have a very similar arrangement with the KPA/KAT500 and three wired Kidde
smoke/ CO detectors.

I've had problems with it periodically over the years in spite of various
attempts to resolve triggering the smoke detectors using various ferrite
cores and bypass capacitors and being as fastidious as I can with grounding
in the shack.

Glad to hear it's working well in your shack

;-)

I'd be interested if anyone has experience running some power with the new
wirelessly interconnected Kidde detectors that create their own rf based
interconnection rather than use the wifi system that may already be present
in the home.

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 and do some further
testing

;-)
