Help please - how to replace Friedland 441 with wired Tapo D130 Smart Video doorbell

[dram773]

The fitting instructions for the wired Tapo D130 tell me to install a jumper wire across the Trans and Front terminals to bypass the existing chime. Unfortunately, the existing chime is an old Friedland 441 and does not have terminals with those labels (see photo). Do I just put the jumper across the terminals with the red and black wires? Many thanks.

It seems to me the wrong way around, I admit, seems they are using the old supply to feed the doorbell. So the doorbell push replaces the original doorbell push, and linking the two wires in the old doorbell means it gets the full supply.

Do I just put the jumper across the terminals with the red and black wires?

Yes.

#ericmark, Yes they do state that the purpose of the jumper is to give the new push the full supply by simply bypassing the old chime unit. Thanks for confirming I can just jumper the two obvious terminals in the old chime unit.
