Honeywell/Resideo Wave2 Siren/Sounder Issues

So For the past three installs I have done I have ran into an issue with the Wave2 sounder from Honeywell/Resideo. I have noticed they redid the whole circuit board to it, use to have through-hole components and now it’s all SMD.

The issue is when it’s connected to a Vista 20 it hums. Sounds what a shorted doorbell chime sounds like. I’m not talking about when the sounder is going off but when it’s at idle. I’ve tried it on Steady and Warble with the same results. I also tried with supervision ON and OFF.

I know it’s the Wave2 sounder because luck would have it I had an older one on my van and when hooked up it worked.

I recommend to use the DSC SD-15W sounder/siren as an alternative.
