Transformer Operation With Wired Gong Module - REV Ritter Ritmo Mode D'emploi

5. transformer operation with wired gong module

Numerous multi-storey apartments have a central bell plate at the ent-
rance to the building with pre-installed alternating current wiring to every
apartment. Remove the cover from the gong and insert 4 x 1.5V batteries
in – take care to ensure they are inserted with the correct polarity.
Connecting the incoming bell lines with T1 and T4 produces a three-tone
sound when the entrance bell is pressed. Connecting the incoming bell
lines to T3 and T4 produces a polyphone melody when the entrance bell is
pressed (refer to point 8 for melody selection).
A second bell can be installed at your apartment door for example at the
same time. Insert 4 x 1.5V batteries – take care to ensure the polarity is
correct.
Connecting the incoming bell lines with T1 and T4 produces a three-tone
sound when the other bell is pressed. Connecting the incoming bell lines
to T3 and T4 produces a polyphone melody when the other bell is pressed
(refer to point 8 for melody selection).
Please observe that it is recommended to only use bell plates that have
no illumination, since the light would lead to the batteries running out very
quickly. These varying connection possibilities enable you to distinguish
calls between two bells, between for example the bell ring of the entrance
door and that of the apartment door.
