• This video distributor is for exclusive use in
GUINAZ video entryphone installations. It will be
installed as specified in this guide, applying
enforced regulation.
• Internal handling of this product will only be
performed by specialised personnel and always
with the equipment disconnected from the mains.
• This device is designed to be installed inside
buildings.

The distributor comes with a 100 W resistance (R 100
W, FIGURE 1) from the factory as the end of the video
J2 (100 ohm)
line when the distributor is the last one along its
distribution branch, that is to say, there is only one
coaxial cable connected to the distributor input.
When the distributor is not the last one along its
distribution branch, that is to say, there is one coaxial
cable connected to the input and another to the direct
M1720D
output, the 100 W resistance MUST BE CUT (see
diagram in FIGURE 2).

DISTRIBUTOR POWER SUPPLY.
Connect to common wire No. 5
To power the distributor, its power supply terminal
block (identified as 14 DIG./10 ANALOG.) will be
connected to the distributor power supply terminal
block of each monitor connected to the branches of
the distributor. This power supply terminal block is
number 10 in analogue monitors and number 14 in
digital monitors. In general, it will not be necessary
to connect any cable to terminal block 2/5 (GROUND)
of the distributor, will be connected to common wire
No. 5 in the case of analogue installations or to wire
No. 2M (or 2P) in the case of digital installations.
