5. Installation and activation of the monitor
Execution of electrical installation
Detailed recommendations regarding the electrical installation of the video door entry sys-
tem can be found in the operating instructions of the CD-2502 or CD-3100 digital door pho-
nes.
The installation should be done using video splitters. You need one splitter for four mo-
nitors. The splitter can act as a central power supply, provided that it is powered from the
15VDC/4A power supply. With this connection the distance between the splitter and the mo-
nitor should not exceed 30m, according to the table in Figure 4. The monitor can also be po
-
wered from a local power supply 13,5V/1,2A. This is recommended if the distance between
the external panel and the monitor exceeds 30m. The video signal should still be fed from
the CVR-2 splitter. For video installations it is recommended to use UTP cat.5.5.
Monitor installation
Monitor should be mounted inside the building in a place easily accessible to the residents,
at a height of at least 1,5 m in such a way that it does not pose a threat to them and is not
exposed to accidental hit.
Do not install the monitor in front of a window or strong light source as this may make it dif-
ficult to observe the image on the monitor screen. It is not recommended to install monitors
in narrow corridors or passageways, as this may cause sound distortion.
The monitor should be mounted at least 1,5 m from sources of strong electromagnetic inter
-
ference – transformer power supplies, magnets, metal sewer and gas pipes, as this may cau
-
se image distortion. It is recommended to place a flush-mounted electrical box with a fixing
socket or an electric switch in the place provided for the monitor installation. Connect the
monitor connection cables in a box. Attach the monitor mounting bracket to the box so that
the holders with the holes will be directed up. Attach the mounting plugs to the cables (Fi-
gure 5 and 6). Insert the plugs into the appropriate sockets, remember to put the power plug
at the end.
Program the monitor number (see section 6 „Programming the number”).
Finally attach the monitor to the mounting bracket and lightly pull it down, overcoming a
slight resistance.
