DESCRIPTION
The module features 12 buttons backlit keypad (Keys 0 - 9 ,
ENTER and CLEAR ) and 2 LED’s for progress information dur-
ing use and programming. With three integral relays each with
common, normally open and normally closed connections and
two inputs to enable the external triggering of relays one and two (for example, push to exit button). Key presses are signalled both
acoustically and visually while each button press has a tactile feel. Entering the correct code followed by ENTER will activate the
relevant relay. Programming is carried out through the same keypad following a simple programming menu. The module can be
combined with other 4000 Series modules in an audio or video intercom system.

relay outputs (24Vac/dc – 5A max);
• 3 Programmable secret codes (one for each relay);
• Each relay can be set to be activated for a speci fi c time (01 to
99 seconds) or to work as latch;
• Two active low inputs to command directly the relay 1 and 2;
• Programming menu guarded by a 4-8 digit programmable
engineer’s code;
• Visual and Acoustic signal during operating and program-
ming;
• Keypad illumination LEDs;
GENERAL DIRECTIONS FOR INSTALLATION
In order to achieve the best results from the schematics de-
scribed 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;
• All multipair cables should be compliant to CW1308 speci fi ca-
tion (0.5mm twisted pair telephone cable).
• Cables for speech line and service should have a max resist-
ance of 10 Ohm
• Lock release wires should be doubled up (Lock release wires and
power supply wires should have a max resistance of 3 Ohm);
• The cable 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 RESIST-
ANCES indicated above;
• Double check the connections before power up;
• Power up the system then check all functions.
