The existing chime is a compatible model per the list. The existing wiring photo is below. Which terminals do I connect the Pro Power Kit to? (They are not labels TRANS and FRONT.)
Hi @user72711. You’ll need to determine which terminal leads to the front doorbell, and which leads to the transformer. The Pro Power Kit would then be installed on those terminals. We have installation instructions for the Pro Power Kit here as well. If you’re not sure how to determine which wires lead where, I’d recommend contacting a qualified electrician for assistance.
