Floor Call
The integrated floor call function presents a convenient option to assign directly at the
apartment door each of the bell buttons at the building door to an additional bell button
(floor call button).
To connect the floor call buttons, first connect eLi/c to c; connect one contact of the
floor call button with ERT – in order to reloop ERT from unit to unit – and the other contact
with the terminal belonging to the apartment, 7.1, 7.2, 7.3 or 7.4.
Note
If the IO module relay between eLi/c and eLi is to be isolated and simultaneously
used for the floor call function, an external accessories diode (for example, Siedle ZD
061-10) will be needed: c is connected to the anode of the diode, while the cathode
is connected to the floor call button (diode conduction direction from c to the floor
call buttons); the other contact of the floor call button is connected to the terminal
associated with the apartment, 7.1, 7.2, 7.3 or 7.4.
Door Opener
Connect the electromagnetic door-switch opener to IO module Do; connect second
connector to c.
