CODELOCK UNIT MODULES ART.4800
The module features 12 stainless steel buttons (Keys 0 - 9, ENTER and CLEAR), 2 LED’s for progress information during use and pro-
gramming 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.
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 capacitor must be fitted across the terminals on AC lock release (Fig.1A) and a diode must be fitted 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 figures.
