Chime Module

[Hideguy]

Has anyone had a problem with chime modules sounding with a constant sound like a Piezo?  I have been experiencing this the last two days at the same time each night with two of them, each on a separate unit code, but same house code. They sound like a siren rather than a chime.
I'm wondering if they are picking up something from the power lines.

I vaguely remember some similar reports awhile ago.
I hope someone with a better memory or has experienced the issue. Can provide more added information and assistance.
As my search of the older messages didn't find the information I was looking for.

Same here. And the worse part is.... I can't recall either the cause or the solution.

But.............If the problem occurred here... with my setup.

My first thought would be what changed on or about the day/time of the first "buzz". Was there something new added to the powerline? Christmas lights? A gift?

I'd then check my activity log.... was there anything happening at the time of the buzz. Timer, sensor, macro?

I don't know of anyway to "cause" the chime to buzz.... so I can't look for that. I might try switching the code (like from A to B) on one to see if that stops the activity on it. If it does... that might lead in the direction of a solution.

If the sound is more like a burglar alarm, then that can happen on chimes when an extended code is issued.  I had that problem when I had noise issues.

I seem to recall threads where CFLs ended up being the culprit.
but I also would suspect something that was causing noise. Bulbs of all flavor have been known to go as they age and cause noise even incandescent ones.

It was the neighbors porch light?

Here's a thread on extended codes causing this.

Problem solved. The help about the two way module and extended codes helped. I changed the two way lamp module to a regular lamp module on one device in the Active Home Pro software and the chime stopped ringing like a siren. Thanks to all the responses.
