Fig. 1
MAIN FEATURES
• 3 C, NC, NO relay outputs (24Vac/dc – 5A max);
• 3 Programmable secret codes (one for each relay);
• Each relay can be set to be activated for a specific 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 programming;
• Keypad illumination LEDs;
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;
• All multipair cables should be compliant to CW1308 specification (0.5mm twisted pair telephone cable).
• Cables for speech line and service should have a max resistance 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 RESISTANCES indicated above;
• Double check the connections before power up;
• Power up the system then check all functions.
LOCK RELEASE BACK EMF PROTECTION
A varistor must be fi tted across the terminals on AC lock release (Fig.1A) and a diode must be fi tted across the terminals on a DC
lock release (Fig.1B) to suppress back EMF voltages. Connect the components to the lock releases as shown in fi gures.

BUZZER BACK EMF
When using intercoms with buzzer call (Art.924/926, SMART1/2, 3101/2, 3001/2 and 3021/2) add one 0.1uF (100nF) capacitor be-
tween terminals 3 and 6 on the telephone.

DESCRIPTION
The module features 12 stainless steel buttons (Keys 0 - 9,
ENTER and CLEAR), 2 LED's for progress information during
use and programming and a mirror finish stainless steel front
plate (Standard version). 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.
