DEFINITION

The Golmar Vista Plus video door entry system kit is a digital system, specially designed to replace the
4+n or conventional electronic door entry system making use of the existing installation. Adding to
this, the fact that the system does not use coaxial cable for video signal transmission (it is transmitted
via an untwisted pair of wires), necessitates a detailed study of the existing installation before installing
the system.
To check that your installation complies with the system's minimum recommended requirements,
please read carefully the following chapters, which provide details of the checks to be done.

MINIMUM REQUIREMENTS

Before installing this system, we must ensure that the existing installation complies with the following
requirements:
-All the wires of the installation must use the same conduit, especially those that carry the
video signal and ground.
-The wires must not be spliced, frayed, nor touch metal parts, and must not vary in cross
section throughout the entire installation.
-The entire installation routing must be at least 40cm away from any other installation
otherwise there is a risk that the audio signal be exposed to interference, or that the
system does not work correctly.
-Any branch connections must be made using D4L-R5 distributors.
-The apartment must have sufficient space to install the video system monitor.
-Maximum distance between the door panel and monitor: 150mts.
-Before connecting the system's power supply, we must ensure that there are NO parallel
units, relays or call repeaters in the apartment. If so, we must disconnect them or replace
them with units that are compatible with the new system otherwise the installation could be
seriously damaged or burnt.
If any of the first three requirements are not met, it will be necessary to replace the installation column.
Golmar has a special cable for this system, its reference number is RAP-8415. The use of this cable
ensures the correct functioning of the system and simplifies the column replacement given that it
contains all the necessary wires for the installation.
