Digital codelock module
A
Fig. 1 Front
DESCRIPTION
The module features 12 buttons backlit keypad (Keys 0 - 9,
ENTER and CLEAR) and 2 LED's for progress information during
use and programming. The codelock unit module has 2 built-in
dry contact relays which can be used to enabling up to 2 in-
dependent services (door-open, gate-open etc.) by typing in
the programmed access codes (up to 1000) followed by enter.
Acoustic and visual (green and red LED's) confirm the use and the programming operations. This module can be used individually
or combined with other modules in a network and can also be included on an audio or video door entry system.
MAIN FEATURES
• 2 dry contact relay outputs, normally open & normally closed (24Vac/dc – 5A max);
• 1000 Programmable 8 digit access codes: each code can be set to activate relay 1, relay 2 or both;
• Each relay can be set to activate for a specific time (01 to 255 seconds) or to work in a latch mode;
• Two active low inputs to trigger relay 1 and 2 (Push to exit inputs);
• Keypad programming menu protected by a 4-8 digit programmable secret code;
• Visual and Acoustic signalling during operation and programming;
• Keypad illumination LEDs;
• PC programming facility (using specific software and RS-485 or USB cable);
• Two operating modes:
» Standard as standalone codelock or VNET LITE network with RS485 bus;
» Network as serial codelock unit connected via RS-485 to a remote control unit Art. 1050 or Art. 1052;
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.
