DESCRIPTION
Vandal Resistant Digital audio/video door entry panel for internal or external use, to work
with the VIDEX VX2200 digital system and is available with a ush back box (VRFB100x270)
as standard or optional surface back box (KR-AV-VR-SB), see Fig.1.
Normally used on installations where each property or apartment requires a local intercom
door station directly outside their property or apartment.
The panel includes an HD colour camera (650 lines with 90º of viewing angle) plus the speaker
unit module and a single call button.
10 Way dip-switch bank (DSW1) of which 8 (1 to 8) are used to set the address of the
videophone to call, the ninth is used to set the door opening time (2 seconds = OFF, 6
seconds = ON). The tenth is not used.
Loudspeaker and microphone volume adjustable through two trimmers on the bottom of
• The KR-AV-VR panel will call the apartment emitting a low volume beep at 2 second intervals (approx.).
• When the apartment answers the conversation can begin.
• When the conversation is nished and the call is closed down the panel will revert back to standby mode.
In the event that the videophone is in privacy mode or if there is no answer (system busy), the call will stop automatically after
approximately 40 seconds.

If the call is answered and the conversation is not closed down by the user the call will terminate automatically after approximately
60 seconds.
To Open the Door from the Videophone (when the conversation is open)
Press the lock button on the Videophone:
• The “REL” output terminal on the panel (see Fig.1 reference “F”) will be triggered and activate the relay connected to the lock
(see Fig.3 and Fig.4 on page 5 for relay and lock wiring).
• The panel will emit 4 quick, successive low volume beeps to indicate the lock has been triggered.
PROGRAMMING & ADJUSTMENTS
Programming options are:
• The Phone ID (address) of the local videophone to call when the call button is pressed (see Fig.1 reference “G”, 10 way dip-
switch bank DSW1, switches 1 to 8).
• The door opening time (the “REL” output) for the electric lock (switch 9).
• Switch 10 is not used.
LOCAL VIDEOPHONE PHONE ID SETUP
Use the rst 8 dip-switches of the 10 way dip-switch bank (see Fig.2) to
set the PHONE ID for the local videophone.
Each switch corresponds to one bit which can have a value of 0 (OFF) or
1 (ON).
Each bit corresponds to a decimal weight depending on the position:
Switch 1 = decimal 1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64 and 8=128
(see table below). I.E to set the address 37, put switches 1, 3 and 6 ON
(1+4+32=37).
DOOR OPENING TIME SETUP
Switch 9 (refer to Fig.2) sets the door opening time (the “REL” output): OFF = 2 seconds, ON = 6 seconds.
VOLUME ADJUSTMENT
Volume adjustment trimmers are available for both the microphone and
speaker which are located at the bottom of the KR-AV unit (see Fig.1
reference “H”).
Mic and Speaker volume adjustments
Turning the mic or speaker adjustment trimmer clockwise will increase
the volume and turning the mic or speaker adjustment timmer counterclockwise will decrease the volume, see Fig.3.

* - 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 oer a low cost solution they will have a higher resistance than pure copper cable and can aect 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.

ELECTRIC LOCK AND VOLT FREE CONNECTIONS
An electric lock (fail safe or fail secure) cannot be connected directly to the KR-AV unit. The “REL” output can be connected to a
remote relay (Art.506N) which can then be connected directly to the lock. An additional 12Vac or dc power supply (depending on
the type of lock tted) may also be required. Follow Fig.4 for fail secure lock release wiring and Fig.5 for fail safe lock release wiring.
If volt free wiring is required, e.g. volt free connections to a set of gate or barrier controls, then simply follow Fig.4 but omit the lock
wiring and instead connect the CO/NO relay terminals directly into the appropriate trigger input on the gate or barrier controls.

• The earth stud connection inside the back box should then be connected in the same way to the building’s earth connection.
PANEL CARE AND MAINTENANCE
As the panel is manufactured from 12 gauge brushed stainless steel it is important that the VR plate is cleaned on a regular basis
to prevent dirt build up and tarnishing. A clean and soft cloth can be used with moderate warm water or non-aggressive cleansers.
Additional care should be taken to follow the grain of the metal when polishing and always only polish in one direction to avoid
light scratching of the plate. Also try to avoid any polish build up around the panel’s button which may prevent the button from
operating correctly.
DO NOT USE ANY OF THE FOLLOWING:
• Abrasive liquids;
• Chlorine-based liquids;
• Metal cleaning products (including Sidol stainless steel cleaner as this can aect the engraving);
• Hydrochloride bleaches.
