Extension of an existing doorbell system:
An already existing doorbell system can be extended with this product.
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 -
60 Hz alternating current. In the event that you are dealing with an
existing doorbell system using direct current, you must connect the
positive terminal of the doorbell to contact C of the transmitter and
the negative terminal to contact A of the transmitter.
