ADC-VDB770 wiring guide

Important: Standard wiring setups require a Power Module (ADC-VDBA-PM) to be installed in the circuit. For more information, proceed to Can the ADC-VDB770 be used without a Power Module?.

Choose the number of VDB770s and chimes connected to the same circuit to view a wiring guide for that configuration.

Wire a VDB770 to a chime

Transformer: 16-30VAC 10-30VA | Power Module: Required | Resistor: Not Required | Chime Type: Mechanical or Digital

Important: Newer ADC-VDB770s will include a battery-less insert (ADC-VDBA-770BL) instead of an internal battery and heater. The new version will be marked on the packaging and by a new hardware version number HWV0310+.

Digital chime installations will require a battery replacement kit (ADC-VDBA-770BAT). For more information about how to use the battery replacement kit, see Replace the battery for the ADC-VDB770.

  1. On the power module, attach the white wires interchangeably to the FRONT and TRANS terminals on the chime.
  2. Attach the gray wires interchangeably to the transformer and the ADC-VDB770.
  3. On the ADC-VDB770, attach the remaining wire to the transformer.

Important: If there is a secondary analog doorbell button wired to the chime, the power requirements and wiring for the ADC-VDB770 are not affected.

Wire a VDB770 to two chimes

Transformer: 16-30VAC 15-30VA | Power Module: Required | Resistor: Not Required | Chime Type: Mechanical or Digital

Important: Newer ADC-VDB770s will include a battery-less insert (ADC-VDBA-770BL) instead of an internal battery and heater. The new version will be marked on the packaging and by a new hardware version number HWV0310+.

Digital chime installations will require a battery replacement kit (ADC-VDBA-770BAT). For more information about how to use the battery replacement kit, see Replace the battery for the ADC-VDB770.

  1. On the first power module, attach the white wires interchangeably to the FRONT and TRANS terminals on the chime.
  2. On the second power module, attach the white wires interchangeably to the REAR and TRANS terminals on the chime.
  3. Attach one of each of the power modules to the transformer using a wire connector.
  4. Attach one of each of the power modules to the ADC-VDB770 using a wire connector.
  5. On the ADC-VDB770, attach the remaining wire to the transformer.
Wire a VDB770 without a chime

Transformer: 15-30VDC, 8W mimimum or 16-30VAC 10-30VA | Power Module: Required | Resistor: 10 Watts 10 Ohms with 5% tolerance | Chime Type: N/A

Using a DC power source

VDB770_no_chime.png

  1. On the power module, attach the white wires interchangeably to a resistor (10 Watts 10 Ohms with 5% tolerance).
  2. Attach the gray wires interchangeably to a DC transformer and the ADC-VDB770.
  3. On the ADC-VDB770, attach the remaining wire to the transformer.
Using an AC power source

  1. On the power module, attach the white wires interchangeably to a resistor (10 Watts 10 Ohms with 5% tolerance).
  2. Attach the gray wires interchangeably to an AC transformer and the ADC-VDB770.
  3. On the ADC-VDB770, attach the remaining wire to the transformer.
Wire two VDB770s to a mechanical chime

Transformer: 16-30VAC 20-30VA | Power Module: Required | Resistor: Not Required | Chime Type: Mechanical Only
