Aiphone Dual Master ChimeCom C-123LW Supplemental Instructions page 4

INSTALLATION TIPS:
1. Use shielded wire for the communication path, and ground one end of the shield to an earth ground.
2. Run intercom wire at least 20" away from AC wiring, fluorescent lights or dimmer switches.
3. Keep intercom cable away from alarm, data, phone, video cables, and any other potential source of
interference.
4. Door release wires must be in a separately jacketed cable from the intercom wires. Use two separate
cables; one for audio and one for door release.
5. When installing a second master station, wire must be run from the first master station, not from the
door station. See diagram on page 2.
6. Do not install the master station near light switches, dimmer switches, or other devices that may cause
interference with the intercom system.
7. Do not install the master station on the opposite wall from the door station. If the units are too close,
acoustical feedback may result.
