How does the Video Doorbell Wall Power Supply Kit work?
The Video Doorbell Wall Power Supply Kit (ADC-VDBA-PSU-PD) is a DC plug-in power supply rated at 16V, 1.25A
(20W). The Video Doorbell Wall Power Supply Kit is designed to easily power the ADC-VDB770 when not using an
existing chime circuit. This supply can be used for installations where there is no existing wiring or where the existing
setup is incompatible.
Important
: The Wall Power Supply Kit should only be installed when no wired chime is used in the circuit.
