Alarm.com Video Doorbell Power Module ADC-VDBA-PM-770

A power module is included with each ADC-VDB770. Additional power modules can be purchased separately.

Power module purpose

• Designed for the ADC-VDB770.
• Enables installers to retrofit existing 10VA (volt-amp) transformers and avoid the need for replacement by allocating all the available power from the transformer to the ADC-VDB770. The additional power allows the ADC-VDB770 to support Video Analytics.
• Blocks electrical currents from running through the chime when the button is not pressed. Doing so prevents humming at the chime.
• Ensures that digital chimes can ring properly.
