Camera works fine, but I can’t get the brand new mechanical chime to work. Installed a new 16V transformer, and it’s working as far as I know. The video doorbell part is functioning too.

I have photos of the original wiring which didn’t make much sense, because there’s 2 lines of CAT5 coming into this box.

I ran a jumper from the other post on the transformer to the chime and it makes the DING but a horrible buzzing sound follows AND it retracts one of the pistons like it’s stuck in the fire position.

Any help would be much appreciated, I am a carpenter not electrician.
