1181. Timed supply for one monitor (or two
Flat monitors) CCD camera, electric lock and
push-button lights, etc.
Note
- The power supply is not provided with fuses,
but all of its outputs are protected against
overloading and short circuiting by tempera-
ture sensors. To reset the power supply, pow-
er must be cut off for about one minute and
can be restored after having eliminated the
defect.
- The power supply must be installed in a dry
place and can be fixed on DIN bar or on a wall
by using the expansion plugs.
Floor distributors
DV2D. Distributor at 2 outputs.
DV4D. Distributor at 4 outputs.
This unit allows video signal distribution for
the 4+1 system without coaxial cable. They
can be wall mounted or recessed in a junction
box.

Installation notes
For correct installation of the video intercom
systems, the following regulations have to be
respected:
- The wires of the system have to run in a
channelling separated from the mains.
- Use section wires adequate to the maximum
distance of the system.
- Link the
-
(minus) and F terminals directly on
the external station, and not on the power
supply. Both the wires are needed, to avoid
possible hum on the sound channels.
