PT5660W. White colour videointercom with
traditional cathode tube with audio-video pri-
vacy, electronic microphone, differentiated
double electronic ringing sounds (modulated
and continuous note) and terminal board for the
connection to the wall-bracket. With two but-
tons, one for control switch ON and one for door
lock release, and 6 supplementary buttons, that
can be added for additional services such as:
control switch ON, intercommunicating calls,
stair lights, door lock release, etc. The buttons
are included in the kit of the videointercom. The
maximum acceptable current to the button ter-
minals is 60mA. For higher currents use relay
unit art.1471.
It can be installed on the wall by using the wall-
bracket art.WB5600 or WB5660 and the back-
box art. 1283. For particular needs it is possi-
ble to separate the common of the buttons
labelled P4, P5 and P6 by cutting the W1
jumper on the wall-bracket. The buttons have
the 2C terminal in common. In this case the
maximum acceptable current to the three but-
tons is 0.5A.

WB5660. The wall bracket includes 2 terminal
boards for connection to the system, it is to be
used when installing videointercoms with extra
buttons and/or 2 differentiated bells.
Located on the wall-bracket terminal board is a
J1 jumper positioned for the intercommunicat-
ing service (position A).
By using the PT5660W videointercoms with
multi-way systems without the intercommuni-
cating service, the audio privacy can be re-
stored by positioning the jumper J1 in B.
Terminals
The terminals from 1 to 14 have the same func-
tions and characteristics as the previous model.
