TFE
- interface conforming to the 4-wire TFE
specification FTZ 123 D12 for the connec-
tion of door stations with amplifiers.
Connections: (drawing 2)
- Connection of a potential-free bell
pushbutton to the contacts KT and +24 V.
The telephone system supports one bell
pushbutton.
- Connection of the DC-free speech circuit
of the TFE to a loudspeaker system or an
audio module AM 20 to the contacts NF
and GND.
- Control of the TFE, of the loudspeaker
system (activation of the amplifier or
power supply) or of the audio module AM
20 (voice/music changeover) via the po-
tential-free relay contacts TS (R4)
Maximum contact load-carrying capacity:
30 VDC/1 A or 123 VAC/0.5 A.
- Control of the door opener via the poten-
tial-free relay contacts T0 (R3)
Maximum contact load-carrying capacity:
30 VDC/1 A or 123 VAC/0.5 A.
You can only activate the door opener
from a terminal of the telephone system
after connecting an external bell trans-
former.
For connection, carry out the following op-
erations:
- Place the connecting leads through the
housing openings.
- Fit the screw terminals onto the connect-
ing leads.
- Insert the screw terminals of the individual
leads onto the provided slots (see draw-
ings 2).
- If you route a connecting lead of the
telephone system outside of the building,
you are advised to use external lightning
protection.
Maximum contact load: 30 VDC/1 A or
125 VAC/0.5 A, ohmic load.
Connecting an audio module or loudspeaker system ¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢
You can connect an audio module or a
loudspeaker system in place of a door hands
free unit or to one of the eight ports for
analog terminals (drawing 5).
The port used to connect the audio module
must be programmed to terminal type "Au-
dio module". With the programming the re-
lay R2 is automatically assigned to the audio
module (TS 1 - TS 2). The relay controls the
speech/music switching of the audio module
for an announcement.
You must connect a resistor 600 ohms/0.5
W to the a/b connections of the "Audio
module" ports.
