If there is no existing wiring powering the chime, you will need to install a power supply/transformer and lead the secondary wires to the chime location.
Before doing any re-wiring, locate the transformer powering the existing chime/doorbell unit and disconnect the secondary wires at the transformer, securing the leads to avoid shorts or arcing.
Since the wires to the doorbell typically run via the doorbell button, and are opened or closed by the traditional doorbell switch, the traditional doorbell button needs to be removed and the wires leading to the doorbell button need to be connected to each other permanently. This maintains the existing power connection to power the device. Also if a rear doorbell is installed the wires leading to the rear doorbell must be disconnected and capped.
Chime Relay Connections
The Axxess Chime relay has 4 flying leads, red, black, blue and yellow.
Connect the following wires as follows:
Red: to one of the leads from the transformer
Blue: to chime contact typically marked “Front”
Black: to chime contact typically marked “Trans/Common”
Yellow: to chime contact typically marked “Rear”
The second transformer lead will connect to the same contact as the black wire, typically marked “Trans/Common”.
Old Wiring Comparison
New Installation Wiring
The same general instructions apply to a new installation. As opposed to an existing installation the transformer wiring can now be connected directly to the chime and chime relay. Wireless Doorbell Buttons and Chime Relays can be mounted anywhere within range of the ZigBee network.
Ensure that neither the wires, nor the chime relay touch the chime sound bars, as even a slight touch will dull the sound. After re-wiring ensure there are no exposed uncapped wires, then reconnect the secondary wires at the transformer.
