2.5.8 TwinBus handsfree intercom unit 1 7230
Assembly
Remove the TwinBus device and the supplied components from the packaging.
Please provide your customers with a copy of the operating instructions for the TwinBus device.
Connection
Connect screening on incoming and outgoing lines. Connect all unused wires as screen for YR lines.
Button adapter 1 4645 must be used when multiple indoor telephones operated in parallel are to react to one
apartment button (ED).
Starting up
Start-up can take place using the handsfree intercom unit or the apartment button. Start-up using the apartment
button is useful if you do not have access to the residential unit.
In order to allow the operator to change the call tone of the main bell button, the main bell button must be programmed
as the main button when initial setting takes place. The procedure must be repeated for other bell buttons.
The intercom can be used for start-up with two persons.
Adjustment protection
The TwinBus power supply unit can be used to give the connected intercom units a setting protection to prevent them
from being changed inadvertently.
A negative acknowledge tone when the setting button is pressed is an indication that the adjustment protection facility
has been activated.
Note:
The handsfree intercom unit 1 7230 is installed in the same way as the compact intercom unit
1 7132 – refer to page

Note:
the speech quality depends on the installation of the device. Install the handsfree intercom unit at
the operator's eye level. When used in combination with the staircase door station, the handsfree
intercom unit must not be coupled acoustically with the staircase door station. Acoustic couplings
are created, for example, by wide joint clearances in doors or air drains in conduits for electrical
wiring.
