INSTALLATION GUIDELINES

  • Aiphone recommends that when installing any of its communication products, the wiring must be run at a distance of at least 2 feet (60cm) from AC wiring, fluorescent lights, or dimmer switches.
  • Aiphone Corporation is not responsible for improper installations of its products which result in interference generated by AC voltage, dimmer switches, fluorescent lighting fixtures, or other similar electrical devices. If noise is induced into the\nintercom system from one of these sources, it must be corrected at the source by the\ninstalling party.

LEF Audio Intercom System Pre-Installation: Wiring

  • Select the proper type of wire for the system being installed. Use the maximum number of conductors for the system. Consult the following wiring information to determine how many conductors will be required for your system, and what gauge is required.
  • 2. Shielded wire is recommended, but not required. It may help to minimize possible interference from outside sources.
  • 3. Use a multi-conductor cable with an overall shield, not twisted pairs.
  • Run the cable in a "daisy-chained" configuration, in and out of each station in the system from beginning to end. Door stations and sub stations may be homerun to the nearest master station in the system.
    • NOTE: Some intercom stations require the same common wires, plus individual wires for each station on the wire run. Assure that the cable has enough conductors for every station included.
  • 5. When running intercom cable, maintain a distance of at least 24" from any AC wiring, fluorescent lighting, and dimmer switches. When crossing AC wires, do so at a 90° angle. Avoid running intercom cable in the same stud space with electrical wiring, and install the intercom station on a different portion of the wall from electrical devices.

Installation:

  • Lay out your system in advance, determining which stations will be located in each room, and what their respective station number will be. Fill in this information on your wiring diagram.
  • 2. Cut the proper sized holes in the wall to semi-flush mount the intercom stations (C-version units only).
  • Separate the intercom from the back chassis by carefully removing the control panel cover and directory strip and loosening the screws. Lift up on the intercom portion before pulling it outward. Unplug the connectors, and store the intercom unit in the box until the wiring is completed.
  • Install the back chassis in the wall, and make wire connections as shown in the appropriate wiring diagram. Be sure to tighten screws securely onto the wires.
  • Reattach the intercom unit to the back chassis with the connectors, and place it on the back chassis from the top. Tighten the screws, and replace the directory strip and cover. Remove the plastic film over the control panel cover.
  • After all connections are made and intercom stations installed, test the operation of the system according to the Owner's Guide. Leave the Owner's Guide with the end-user for their use.
  • Fully train the end-user as to the functions and features of their intercom system. Advise the end-user on which rooms are assigned to each station number so they can fill in the directory card on each station.

(1) LEF-10C Music Center System, w/ one audio door station;

The BGR-10A Music Control Center provides the All Call, Door Chime, and Radio features. For receiving a chime from the door and making an all call from the LEF-1C stations, the BGR-10A is required in the system.

(2) LEF-10C Music Center System, w/one video door station;

The BGR-10A Music Control Center provides the All Call, Door Chime, and Radio features. For receiving a chime from the door and making an all call from the LEF-1C stations, the BGR-10A is required in the system.

(1) PLACING AN ALL CALL;

Depress and hold down the ALL CALL button while making an announcement (Occupied light will turn on). Upon completion, simply release the button. To receive an answer back, another All Call can be made from a sub-master, or a master station can selectively call to the station that made the All Call.

Note: By depressing OFF button, the system is in "standby" mode, and ready to accept another call. When the system is not in use, all OFF buttons should be depressed. Only the initiating master's OFF button should be up during communication.
