Heath Zenith chime compatibility

[smitty55]

Have a Health/Zenith 95 Base wired chime (ten years old). Looking to keep current chime and add the wired Arlo. Arlo states I need at least a 16-24v chime system with a 10v transformer. The Heath is right at 16v with what appears to be a 10v transformer. The transformer reads "16v 10va." Seems compatible but thought I'd ask others with better knowledge, similar set-up.

Be careful not to mix up v (volts) and va (volt-amperes - roughly watts). 

16v 10va is within the spec for the doorbells.
