Art.4800 - 4800M Digital codelock module

CODELOCK UNIT MODULES ART.4800  4800M

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 nish 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 speci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 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 specication (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  tted across the terminals on AC lock release

(Fig.1A)

and a diode must be  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  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 be­tween terminals 3 and 6 on the telephone.

BUILTIN RELAYS  BACK EMF PROTECTION ART.4800M

The Art.4800M includes selectable back EMF protection on the relays. The jumpers marked MOV (One jumper for each relay) are
used to select the protection type. When using a fail secure lock with connections C & NO the jumper should be in the NO position.
When using a fail open lock with connections C & NC the jumper should be in the NC position and when using the codelock to
trigger a gate controller or another third party controller the jumper should be removed completely (This disables the protection
on the relay).

PROGRAMMING SEE ALSO THE RELEVANT FLOW CHART

• Enter the “ENGINEER’S CODE”: rst time type six times “1” (111111 factory preset) and press “ENTER” (The red LED will illuminate);

• Conrm “ENGINEER’S CODE” (typing again the same) or type the new code (4 to 8 digits) then press “ENTER” (Melody). Pressing
twice the “ENTER” button without changing the “ENGINEER’S CODE”, will exit from the programming;

• Enter the code (4 to 8 digits) to enable “RELAY 1” or re-enter the existing code then press “ENTER” (Melody);

• Enter the “RELAY 1” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or re-enter the existing time then
press “ENTER” (Melody);

• Enter the code (4 to 8 digits) to enable “RELAY 2” or re-enter the existing code then press “ENTER” (Melody);

• Enter the “RELAY 2” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or re-enter the existing time then
press “ENTER” (Melody);

• Enter the code (4 to 8 digits) to enable “RELAY 3” or re-enter the existing code then press “ENTER” (Melody);

• Enter the “RELAY 3” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or re-enter the existing time then
press “ENTER” (Melody);

• The system is ready to use (the red LED will be o).

PROGRAMMING NOTES

• After pressing enter following a command, press “ENTER” a further twice to exit the programming menu.

RETURN SYSTEM TO PRESET ENGINEER’S FACTORY CODE

• Turn o power to code lock;

• Keep “ENTER” button pressed while turning the power back on;

• Release “ENTER” button;

• The engineer’s code is now set to “111111” (six times one).

OPERATION

• Type in the programmed code and press “ENTER”;

• If the code is correct, the green LED will illuminate for ap­prox. 2 seconds and the relay relevant to the code will oper­ate for the programmed time;

• If a wrong code is entered, a continuous melody will sound
for 4 or more seconds, according to the number of mistakes;

• To switch o any relay while operating, type in the relevant
code then press the “CLEAR” button;

OPERATION NOTES

• To operate relays together, set the same code for each relay;

• If a wrong code is entered, the system will lock out for 5 sec­onds which will increase each time a wrong code is entered.
The system will operate only when the correct code is entered.
