TFE Module 402
The TFE module 402 features two interfaces
conforming to the 4-wire TFE specification
FTZ 123 D12 for the connection of door
stations with amplifiers.
Connections (Figure 10):
- Connect a potential-free bell pushbutton
to the contacts KT and KT’ (GND)
- Connect the DC-free speech circuit of the
TFE of the loudspeaker system to the con-
tacts NF and NF’ (GND)
- Control of the door opener via the poten-
tial-free relay contacts T0
Maximum contact load: 30 V TC/1 A
You can only actuate the door opener
from a terminal of the telephone system
after connecting an external bell trans-
former.
- Control of the TFE or of the loudspeaker
system (activate the amplifier or power
supply) via the potential-free relay con-
tacts TS
Maximum contact load: 30 V DC/1 A
TFE Module 403
The TFE module 403 features an interface
(TFE 1) conforming to the Telekom 2-wire TE
(CE interface) specification. The telephone
system supports up to four bell
pushbuttons.
Connections (Figure 11):
- Connect the DoorLine T01 to T04 door
hands free units to the contacts NF and
NF’
- Controlling the door opener
Maximum contact load: 30 V DC/1 A
You can only actuate the door opener
from a terminal of the telephone system
after connecting an external bell trans-
former.
The TFE module 403 also has an interface
(TFE 2) that conforms to the 4-wire TFE
specification FTZ 123 D12 for the connec-
tion of door stations with amplifiers. The tel-
ephone system supports one bell
pushbutton.
A loudspeaker system or an audio module
can be optionally connected to the FTZ 123
D12 interface for announcements.
Connections (Figure 11): as described adja-
cently for the TFE module 402
Marking cables
- Use the included marking system to mark
the cables
- Strip 11 mm off the wires
- Push the individual wires into the terminal
until they move no further, but
without
pressing the terminal spring.
- To separate a connection, use a suitable
object (screwdriver with a narrow blade)
to press down the terminal spring and
pull out the wire.
We advise you to install external lightning
protection if you route a connecting lead of
the telephone system outside of the build-
ing.
