4.6.6 Checking connection
How to check whether installation was successful:
1. Apply the voltage supply.
ð The DoorLine starts up. After the voltage is applied, a tone sounds
(beep).
2. Call the DoorLine from a telephone that is connected to your telephone
system (see chapter Calling the DoorLine [ } 42]).
ð A double tone sounds in the telephone. The voice communication
between telephone and DoorLine is then built up.
If the device does not react, disconnect it immediately from the power-supply
system. Then check the connection to the power unit for a wiring fault.
If installation was successful, start the configuration of the device as described
in the following chapters.
