GENERAL DIRECTIONS FOR INSTALLATION
In order to achieve the best results from the schematics described it is necessary to install only original VIDEX equipment, strictly
keeping to the items indicated on each schematic and follow these General Directions for Installation:
• The system must be installed according to national rules in force, in any case the running of cables of any intercom unit must be
carried out separately from the mains (see the next paragraph for connection to mains and power supply installation);
• All multipair cables should be compliant to CW1308 specication (0.5mm twisted pair telephone cable);
• Cables for speech line and service should have a max resistance of 10Ω;
• Lock release wires should be doubled up (Lock release wires and power supply wires should have a max resistance of 3Ω);
• The cables sizes above can be used for distances up to 50m. On distances above 50m the cable sizes should be increased to keep
the overall resistance of the cable below the RESISTANCES indicated above;
• Double check the connections before power up; 3 Power up the system then check all functions.
CONNECTION TO MAINS AND POWER SUPPLY MOUNTING INSTRUCTIONS
The system must be installed according to national rules in force, in particular we recommend to:
• Connect the system to the mains through an all-pole circuit breaker which shall have contact separation of at least 3mm in
each pole and shall disconnect all poles simultaneously;
• The all-pole circuit breaker shall be placed for easy access and the switch shall remain readily operable.
POWER SUPPLY INSTALLATION
• Remove the terminal side covers by unscrewing the retaining screws;
• Fix the power supply to a DIN bar or directly to the wall using two expansion type screws;
• Switch o the mains using the circuit breaker mentioned above and then make the connections as shown on the installation
diagrams;
• Check the connections and secure the wires into the terminals;
• Replace the terminal covers and x them using the relevant screws;
• When all connections are made, restore the mains.
(Fig.1B) to suppress back EMF voltages. Connect the components to the lock releases as shown in gures.

Wiring Guide Line
All intercoms wiring must run separately from the mains cable.
The cable type should be CW1308 or an equivalent cable. The cable size should comply with the table below.
DISTANCE METERS CABLE SIZE MM2
50 0.35
100 0.5
200 0.75
300 1.0
400 1.5
Max resistance of all lines: 8 Ohm
Before powering the system up, the wiring should be double checked to ensure it complies with the wiring diagram supplied.
TROUBLE SHOOTING GUIDE
In the event of the system not functioning correctly when you power up, the following points can be checked (a multimeter will be
needed).
SYSTEM DEAD
• Check mains input to the transformer.
• Check the 12Vdc (+12 terminal) output from the power supply.
• Check fuses.
• Check for shorts on power supply wires.
SPEECH & LOCK WORKS BUT NO ELECTRONIC CALL TONE
• Check the link between “C” and “C1” terminals of the speaker unit.
• Call wire to terminal “4” of the handset broken on in short circuit; check the walk of the call wire.
NO SPEECH FROM THE DOOR PANEL
• Check and/or adjust the volume operating on trimmers controls on rear of speaker unit.
• Check the wire from terminal “2” of the speaker unit to terminal “2” of the handset.
NO SPEECH FROM THE HANDSET
• Check and/or adjust the volume operating on trimmers controls on rear of speaker unit.
• Check the wire from terminal “1” of the speaker unit to terminal “1” of the handset.
LOCK DOES NOT WORK
• Check on the handset the link between terminals “1” and “5”.
• Check the 13Vac output on the transformer.
• Check the wires of the electric lock.
• Wires section not in conformity with the table above.
FEEDBACK PROBLEM LARSEN EFFECT
• Check that the handset microphone is rmly tted inside its housing.
• Check that the speaker unit microphone is rmly tted inside its housing and nothing is obstructing the microphone hole.
• Adjust the volume operating on trimmer controls on rear of the speaker unit.
HUM ON THE SPEECH LINES
• Check that system cables are not running close to any high voltage or mains cables.
• Check that the system is wired exactly as shown on the wiring diagram.
WE RECOMMEND THIS EQUIPMENT IS INSTALLED BY A COMPETENT ELECTRICIAN, SECURITY OR COMMUNICA
TIONS ENGINEER.
