3.2.1 Notes on the use of an electronic door opener
There is an increased risk of burglary if you connect a door opener as the relay
contacts for activation of the door opener are accessible following disas-
sembly of the DoorLine.
An electric door opener does not substitute door closure by a locking bar, it is
an intelligent, additional safety feature.
It is primarily intended for daytime operation, whereas at night time or in case
of absence the relevant door is locked by the locking bar.
As far as insurance is concerned, a door that is held closed only by the use of
the door opener is not regarded as locked!
3.3 Technical prerequisites
▪ The device is designed for connection to an analogue telephone connec-
tion (a/b-Port) of a PBX system.
▪ Both relay switching outputs of the device connect potential-free. This
means that when a door opener or a similar device is activated, it may be
necessary to provide an additional bell transformer (see chapterConnect-
ing device [}12]).
▪ The installation of your PBX system and its operation require the use of tele-
phone plugs (e.g. TAE or RJ11), cables and lines that are not included in the
scope of supply.
▪ Your PBX system and end devices (telephones) must support touch-tone di-
alling (DTMF).

4.6 Connecting device
4.6.1 Important notes
▪ Before connecting the device to the PBX system, switch off all required
components (PBX system, device, bell transformer).
▪ When wiring, ensure that the input voltage is correct (9-24 V). The polarity
can be ignored.
▪ Do not insert the wall power supply into the socket until all cables are firmly
connected and there is no risk of a short circuit of wire pairs.
▪ A bell transformer (e.g.12 V alternating voltage) must not be used as a
power supply for the device. This can result in destruction of the device!
▪ Both integrated relay contacts connect potential-free, i.e.an additional
bell transformer is required to activate a door opener. Then connect the
bell transformer voltage via the respective relay switching output to the
door opener (see chapter Connection example for a door opener and a
door bell [}16]).
▪ Both switching relays can be loaded to a max. of 24VAC/DC1 A. Prior to
initial operation of the device, ensure that these values are not exceeded
by your door opener, door bell or other devices to be connected. Observe
the Operating Instructions of the respective products.
4.6.2 Wiring
Use commercially available telecommunication cables for the installation wir-
ing.
Please note that in order to meet general safety provisions and to avoid inter-
ference influences, the low-current telephone lines must be routed separately
from power lines.
Observe a minimum distance of 10 cm between both types of lines. If one of
the connected lines is routed out-of-doors, you will have to provide sufficient
lightning protection.

Connection types
At the analogue connection of the PBX system, three connection types are
usually used in Germany:
▪ Terminals
▪ RJ 11
▪ TAE plugs
On modern PBX systems such as the AVM Fritz!Box or Telekom Speedport, the
two inner wires of the RJ 11 connection should be used.
On older PBX systems (before 2005), the two outer wires are also used.

4.6.6 Checking connection
How to check whether installation was successful:
1. Apply the voltage supply.
ðThe 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]).
ðA 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.

5.3 Acknowledgement tones
During programming, you will be informed about the positive and negative ac-
knowledgement tones via the programming status.
Each note symbol corresponds to a beep:
neutral Key input is expected ♪
positive The programming has been accepted ♪♪
negative The programming has not been accepted ♪♪♪♪♪♪♪♪
5.4 Saving and ending configuration
To end the configuration, it is sufficient to hang up the telephone receiver. The
device then detects the end of the call automatically and saves the changed
configuration.
5.5 Information on the entry of call numbers
Input Effect
* Does not result in the selection of this character but rather a di-
alling pause of one second
** Results in one-time dialling of a "*" character
If you reach your desired telephone via the call number "**1",
you have to enter "****1" in the call number input of the Door-
Line
# The DoorLine generates a flash pulse of 100ms
## Results in one-time dialling of a "#" character
5.6 Entry to configuration mode
For configuration, you have to call your DoorLine with a touch-tone dialling
telephone. The way you can call the DoorLine depends on the configuration of
your PBX system.
When the connection to the device has been established, you can start with
the configuration.

5Configuration
20 / 52 DoorLine TM4
Notes
▪ Write down the corresponding codes for your own reference before you
start the configuration.
▪ When the discussion duration elapses (factory setting 1 minute), the con-
nection is disconnected automatically even during programming.
▪ If the programming is rejected by the device (negative acknowledgement
tone), you will have to repeat the incorrect programming step.
▪ If you entered the wrong PIN three times in succession, the connection is dis-
connected.
1 Pick up the receiver
2 Call the device
You will hear the positive acknowledgement tone
3 Actuate the hashtag button twice on the telephone
You will hear the neutral acknowledgement tone
4 Enter the PIN
You will hear the positive acknowledgement and are now
in programming mode
If you hear the positive acknowledgement tone, you can start with the pro-
gramming. Otherwise the procedure must be repeated.
If you are in programming mode, you can carry out all configuration options
one after the other.
5.7 Automatic adjustment to the PBX system
To guarantee optimum hands-free talking in all PBX systems, your device can
adjust automatically to the respective system.
The adjustment takes around 3seconds. An adjustment tone sounds during this
procedure. During this period, you should not talk into the receiver because this
can interfere with the automatic adjustment.
