Digital codelock module
CODELOCK UNIT MODULES ArT. 4900 - 4900M
This module has on the front a 12 stainless steel button key-
pad (keys from “0” to “9” plus “ENTEr” and “CLEAr” keys), 2
LEDS for operation signalling, the keypad illumination LEDs and
a mirror stainless steel front plate (standard version). Codelock
unit module has 3 built-in relays that allow enabling up to 3 ser-
vices (door-open, gate-open etc.) by typing the programmed
secret codes. Acoustic and visual (green and red front LEDs)
signals facilitate the use and the programming operations. This
module can be used individually or combined with other mod-
ules on an audio or video door entry system.
MAIN FEATUrES
• 3 C, NC, NO relay outputs (24Vac/dc – 5A max);
• 100 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 secret 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.
