Alarm.com ADC-VDBA-PM-750 is a power module used with the ADC-VDB750 wired video doorbell to enable and regulate power to a digital chime. The module connects with two non-polarized wires (one to each doorbell terminal) and regulates chime power while the doorbell button is pressed to ensure proper ringing and prevent damage. It is required for ADC-VDB750 digital chime installations and is not interchangeable with the ADC-VDB770 module.
