3 INSTALLATION & WIRING
■ When replacing an existing doorbell:
Check to see how the existing doorbell Is wired.

Method 1:
If there are only two matching colored wires located at the existing inside bell, the AC
transformer was likely wired in series with the bell and button. If so, take the wires off of
the AC transformer and splice them together, making a continuous wire to the bell.
Measure the AC voltage with a volt meter. However, Aiphone is not responsible for any
damage caused by power surge. Two additional wires must be run from the transformer
to the location where the CC-1M room station will be installed. The two wires from the
doorbell button must be connected to the RED/BROWN wires of the CC-1M, with NO AC
voltage on the wires. Two wires from the AC transformer connect to the WHITE wires of
the CC-1M room station. Remove the doorbell button outside and reconnect the two wires
to the RED/BROWN wires on the CC-DA. Mount CC-DA to wall.

Method 2:
If there are two matching colored wires connected to the bell, and two(or more)
additional matching colored wires spliced together but not connected to the bell, then
there are likely enough wires to connect the Chime Com 2 without running new wire.
1. Take wires off of bell, and separate the wires that are spliced together.
2. Locate the bell transformer currently installed, disconnect it from the existing bell, and
measure the AC voltage with a volt meter. However Aiphone is not responsible for
any damage caused by power surge. Connect the pair from the AC transoformer to
the WHITE wires on the CC-1 M. Connect the other pair of wires (which go to the
door) to the RED/BROWN wires on the CC-1 M.
3. Outside, remove the doorbell button, and connect the two wires to the CC-DA door
station, then mount on the wall.
NOTE: When the inside room station is to be installed in a different location, splice
wires from the existing doorbell location and run new wire to the desired location
for the new room station. Either leave the existing doorbell on the wall but
disconnected, or remove it and patch the wall as needed.
■ How to measure AC no-load voltage
Primary input
Turn off circuit breaker powering AC transformer, and disconnect secondary output
wires. Turn circuit breaker back on, and measure secondary output terminals with a
volt meter. If the reading is between 12-20V, it can be used to power the CC-1M.
If you cannot safely perform this function, or if the transformer does not meet the
specification, install a standard AC outlet and use the Aiphone PT-1210N plug-in
transformer.
■ Power supply
The power source for the CC-1M must meet the following specifications:
• AC no-load voltage: Min. 12V, Max. 20V.
• UL LISTED and Class 2 rated or marked.
• Ratings: 12-16V AC, 10VA or more.
■ Second room station
Another CC-1M station can be added to the system. It requires a separate power
supply, and is to be wired (polarized) from the first inside station (not the door).
