4. Systems with two different
door chimes
If your intercom is capable of diffe-
rentiating between 2 different door
chimes (e.g. the door to your flat and
the entrance door to the building),
you can convey the 2 door chimes to
the combi I RF transmitters using 2
connection cables.
To do this, connect the 2.5 mm jack
plugs of the 2 connectioncables into
the sockets on the combi I RF trans-
mitters. Route the cables to the 2
doorbells and connect the 2 pairs
of bare wires to the doorbell swit-
ches.
Important: The triggering system is
only suitable for connection to low-
voltage doorbell systems. The input
voltage must be at least 3 volts and
no more than 15 volts. It is possible
to connect to either alternating or
direct current voltage.
Never connect the thin cable to
mains voltage (230 V ( 10%).
Risk of fatal injury and irrepara-
ble damage to the transmitter!
Possible reasons for the unit not
functioning
- You did not press the doorbell for
long enough. Ring the bell for lon-
ger.
- If your doorbell system uses direct
current voltage, you have not
connected the wires with the cor-
rect polarity. Swap over the wires.
- The doorbell voltage of your
system is too low. Either contact
an electrician to have the doorbell
system converted or use the
Radio Doorbell Transmitter -
Acoustic.
Call button
Pressing the call button on the
combi I RF transmitter causes a sig-
nal to be triggered on every receiver
which is set to the same radio chan-
nel as the transmitter. The call but-
ton lamp lights up to indicate this.
This makes it possible to call people
who are in different rooms. Also,
this button can be used for checking
the system is functioning even when
the cable are not connected.
Mains operation
You can also operate your combi I
RF transmitter via the plug-in power
supply unit. To connect the PSU, ins-
ert the connector on the end of the
PSU cable into the corresponding
socket on the left-hand side of the
device. Then plug the power supply
unit into the normal 230 V socket in
your house.
