Connecting the transmitter
to a existing bell system (see Fig. I)
Extension of an already existing doorbell system:
An already existing doorbell system can be extended with this wire-
less doorbell.
The operating voltage of the doorbell system must be between 4–12 V.
It makes no difference whether this comes from direct current or 50 Hz
alternating current. In the event that you are dealing with an existing
doorbell system using direct current, you must connect the positive ter-
minal of the doorbell to contact C of the transmitter and the negative
terminal to contact A of the transmitter.
IMPORTANT! Never reverse polarity. This can damage the device.
The connection terminals A and C, found on the circuit board of the
transmitter as shown in fig. I must be connected directly to the electri-
cal connection terminals of the signal generators (e.g. bell). The
button of the transmitter may also be used for this type of operation.
Note: Contact a qualified electrician in case of problems during
