connecting two Nutone Model KB-10 to nest

[b78772]

I have two existing Nutone’s Model KB-10 door bell chimes hooked up in parallel.  They have worked fine since 1995 with the existing transformer which has a rated output of 16 volts 20va.  I wired the Nest per the below diagram and installed a new HVAC 120/208/240-Volt (Primary) 24-Volt (Secondary) 40VA Rating Transformer.  I cannot get the second door bell to ring.  What do I do now to get the second chime to work?

You should re-post this in the Doorbell section.
