    Power supply for camera doorbell.

    I cannot find existing wires for old doorbell. So I fitted a battery digital doorbell. I now wish to replace it with a Zmodo camera doorbell and require the old doorbell leads. (still cannot find them. However I have a redundant light switch on the inside wall opposite where I wish to fit the new doorbell on the outside wall, I only have to drill through and connect. Will the above fit an existing light switch box? I am confused with the statement 16volt 10VA. I need 16volts DC to power the new zmodo doorbell, will this trans. do? Thank you. David.
    Asked by: DC
    Thank you for your question. You will need to contact Zmodo for further assistance. All of our chimes operate on 16V AC at 10VAC.

    Can one transformer power multiple doorbells?

    Can one C915 transformer power 3 doorbells, or do I need 3 separate transformers?
    Asked by: Ohio
    Thank you for your question on the model C915 junction box chime transformer. The C915 is designed to operate one chime only. When you wire three chimes together, you would need a transformer that is rated for 16 volts AC and at least 30 volt amps (watts). Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

    Does this have a timer or does it supply power constantly?

    I want to use this with the ring doorbell and it needs power constantly.
    Asked by: amale
    Thank you for your question on the model C915 junction box transformer. The C915 would be powered constantly. At this point, we have not seen any of our chimes that would be compatible with the Ring Doorbell.
