I have just purchased a Ring video doorbell and have just installed it. The Ring doorbell is working successfully but my internal digital doorbell doesn’t chime any longer when the new bell push is pressed.
When I installed the Ring device I tried the diode both ways round as recommended, but without success either way.
My existing doorbell system is as follows:
A Honeywell series 9 DW915S digital doorbell with wired bell push and power from a low voltage transformer (Hager ST301 4VA 12v)
Can anyone offer any suggestions of what to try next?
