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 switches.
I I m m p p o o r r t t a a n n t t : : 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 dir-
ect current voltage.

- 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 con-
nected the wires with the correct
polarity. Swap over the wires.
- The doorbell voltage of your sys-
tem is too low. Either contact an
electrician to have the doorbell sys-
tem converted or use the Radio
Doorbell Transmitter - Acoustic.

Pressing the call button on the combi
I RF transmitter causes a signal to be
triggered on every receiver which is
set to the same radio channel as the
transmitter. The call button 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.

You can also operate your combi I RF
transmitter via the plug-in power sup-
ply unit. To connect the PSU, insert
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.
