Installation Of Distributor Cvr-1 And Cvr-2 - Laskomex CD-2502 Series Installation, Service And Programming Manual

6.5 Installation of distributor CVR–1 and CVR–2
distributors, switches) to wire impedance.
Load at C1 input should be set only in one of the switches - installed at the end of
the line (by means of JP1 joint) in others all jumpers should be removed from the
joint. Load at input C2 should be set in each switch (joint JP2). Load in outputs
X and Y should be set in each switch (joints JP6 and JP7). Load value for inputs
and outputs should be selected for connection wire.

6.5 Installation of distributor CVR–1 and CVR–2
Floor distributors CRV-x should be installed in staircases in which video entry
phone is installed.
Distributor is fastened to the wall by two screws. Four screws should be driven to
mount the casing cover to its base. After taking off the cover, make openings in
the base for mounting screws (W1, W2, dwg. 14), apply it to the wall and mark
the places for strut pins. Drill openings in the wall, put plastic elements of strut
pins in them and screw the base tot the wall. Then connect wires L+, L- and C+,
C - to terminals ARK. Wire should be routed from one distributor to the next one.
It is forbidden to connect distributors (or their parts) with electronic cassette by
separate wires.
Apply for CVR-1
On the ends of wires from monitors converging at the distributor clamp the plugs
RJ 45 paying special attention to correct order of wires in the plug. (see dwg. 15).
Plugs should be put into distributor sockets. Distributor does not require individual
power supply adaptor – it is supplied from any monitor which is connected with
them - terminals VC and GND.
Apply for CVR-2
Distributor require 15V DC stab./4A external power supply adaptor which allowed
to load each of 4 outputs by the current of 1A to supply monitors (+15V, GND).
