Refer to the table below for the power supply output connections to the
KR-AV-VR
panel and the lock release connections.

Ideally the power supply should be located as close to the
KR-AV-VR
panel as possible for best performance. The maximum
acceptable resistance for the above cables = 3Ω or less for best possible performance.
For other VX2200 system devices refer to the following table. It is recommended that a twisted pair cable is used for the
L
and
-
databus connections and for balanced video signal connections
V1-I / V1-O
and
V2-I / V2-O
.

* -
these connections are only required on video systems.
** -
these are optional connections (e.g. door monitoring LED).
The maximum acceptable resistance for all the above connections (except
+20V
and
GNDV
) = 7.5 Ohms and the maximum
acceptable resistance for the video connections
+20V
and
GNDV
= 5 Ohms for best possible performance. Please note that all cable
sizes shown in the tables above are the minimum cable requirements. Also note that additional consideration should be given
when selecting and using internal and external grade cable and should be used where appropriate.
IMPORTANT NOTE: Only bare copper (BC) cable should be used (solid or stranded is acceptable)
.
Please be aware that when
selecting a cable the following should NOT be used: Copper Coated Steel (CCS) and Copper Clad Aluminium (CCA). While these
types of cable may offer a low cost solution they will have a higher resistance than pure copper cable and can affect the overall
performance of the system therefore Videx DO NOT recommend these types of cable.
Further cabling information can be found in the technical manual
VX2200Blocks1-2
and is also provided in any accompanying
installation instructions with the various audio/videophones and hands-free devices.
GENERAL INSTALLATION NOTES
• Check that all components are free from damage before installing (
DO NOT proceed with installation in the event of damage
).
• Keep all packaging away from children.
• Do not obstruct the ventilation openings or slots on any of the devices.
• All connections to mains voltages must be made to the current national standards (I.E.E. wiring regulations for the UK or the
appropriate standards of your country).
• Install an appropriate fused spur or isolation switch to isolate the mains where necessary and always isolate the mains before
carrying out any maintenance work on the system.
• Avoid water ingress into the rear of the panel (or other devices) always seal the panel’s back box frame during installation using
a suitable silicon based sealant (also refer to back box installation notes on pages 6 and 7).
• All intercom and access control cables must be routed separately from the mains and other high voltage cables (ideally in
separate cable ducts/trays or where this is not possible should be kept apart at a distance of no less than 30cm (12” approx.) if
running in the same cable duct/tray.
