2 jumper cables needed for 2 video doorbell wired

I have 2 video doorbell wired doorbells wired to a mechanical chime with a 40VA doorbell transformer. Following the instructions I have a jumper between the front and transformer screws in the chime. Should I have a second jumper in place between the back and transformer screw?

Thanks in advance.

Hi @ElectricianJim. I checked with my team on this, and they let me know that both jumper cables will be needed, Trans to Front and Trans to Back, in order to bypass the chime kit. I’d also like to note that a 16V 30VA transformer is recommended for this installation. I hope this helps answer your questions! :slight_smile:
