Audiokit 4KC Series

General Directions for Installation

To achieve the best results, install only original VIDEX equipment, strictly following the schematics and these General Directions for Installation:

• Install the system according to national rules in force. Run intercom unit cables separately from mains cables (refer to mains connection and power supply installation).
• All multipair cables must comply with CW1308 specification (0.5mm twisted pair telephone cable).
• Cables for speech line and service should have a maximum resistance of 10Ω.
• Lock release wires should be doubled up (lock release and power supply wires) to have a maximum resistance of 3Ω.
• The specified cable sizes are suitable for distances up to 50m. For distances over 50m, increase cable sizes to keep overall resistance below the indicated limits.
• Double-check all connections before powering up.
• Power up the system and then check all functions.

Connection to Mains and Power Supply Mounting Instructions

Install the system according to national rules in force. We recommend:

• Connect the system to the mains via an all-pole circuit breaker with contact separation of at least 3mm in each pole, simultaneously disconnecting all poles.
• Ensure the all-pole circuit breaker is easily accessible and its switch is readily operable.

Power Supply Installation

• Remove terminal side covers by unscrewing retaining screws.
• Fix the power supply to a DIN bar or directly to the wall using two expansion screws.
• Switch off the mains using the circuit breaker, then make connections as shown in the installation diagrams.
• Check connections and secure wires into terminals.
• Replace terminal covers and fix with screws.
• Restore mains power once all connections are made.

Lock Release Back EMF Protection

A varistor must be fitted across the terminals on AC lock releases, and a diode across DC lock releases to suppress back EMF voltages. Connect components as shown in figures.

Diagrams illustrating back EMF protection for lock releases: Fig. 1A shows a varistor (MOV) for a 12V AC lock release, and Fig. 1B shows a diode (1N4002) for a 12V DC lock release.

Wiring Guide Line

All intercom wiring must run separately from the mains cable. The cable type should be CW1308 or equivalent. Cable size must comply with the table below.

Maximum resistance of all lines: 8Ω.

Before powering up, double-check wiring against the supplied diagram.

Trouble Shooting Guide

If the system does not function correctly after power-up, check the following points (a multimeter may be needed):

System Dead

• Check mains input to the transformer.
• Check the 12Vdc (+12 terminal) output from the power supply.
• Check fuses.
• Check for shorts on power supply wires.

Speech & Lock Works But No Electronic Call Tone

• Check the link between "C" and "C1" terminals of the speaker unit.
• Check the call wire to terminal "4" of the handset for breaks or short circuits.

No Speech from the Door Panel

• Check and/or adjust the volume trimmer controls on the rear of the speaker unit.
• Check the wire from terminal "2" of the speaker unit to terminal "2" of the handset.

No Speech from the Handset

• Check and/or adjust the volume trimmer controls on the rear of the speaker unit.
• Check the wire from terminal "1" of the speaker unit to terminal "1" of the handset.

Lock Does Not Work

• Check the link between terminals "1" and "5" on the handset.
• Check the 13Vac output on the transformer.
• Check the wires of the electric lock.
• Verify wire section conforms to the table above.

Feedback Problem (Larsen Effect)

• Ensure the handset microphone is firmly fitted inside its housing.
• Ensure the speaker unit microphone is firmly fitted and unobstructed.
• Adjust the volume trimmer controls on the rear of the speaker unit.

Hum on the Speech Lines

• Check that system cables are not running close to high voltage or mains cables.
• Ensure the system is wired exactly as shown on the wiring diagram.

Recommendation: This equipment should be installed by a competent electrician, security, or communications engineer.

Art. 4800 - 4800M Digital Codelock Module

Codelock Unit Modules Art. 4800-4800M

This module features 12 stainless steel buttons (0-9, ENTER, CLEAR), 2 LEDs for status and programming, and a mirror-finish front plate. It includes three integral relays (common, normally open, normally closed) and two inputs for external triggering (e.g., push-to-exit button). Key presses provide acoustic and visual feedback. Entering the correct code followed by ENTER activates the relevant relay. Programming is done via the keypad using a simple menu. The module can integrate with other 4000 Series modules in audio or video intercom systems.

Main Features

• 3 C, NC, NO relay outputs (24Vac/dc – 5A max).
• 3 Programmable secret codes (one per relay).
• Each relay can be set for a specific activation time (01-99 seconds) or latch mode.
• Two active low inputs for direct relay 1 and 2 command.
• Programming menu protected by a 4-8 digit engineer's code.
• Visual and acoustic signals during operation and programming.
• Keypad illumination LEDs.

General Directions for Installation

Follow the same general directions as for the main Audiokit system (see above), including mains separation, cable specifications (CW1308, resistance limits), and connection checks.

Lock Release Back EMF Protection

A varistor must be fitted across AC lock release terminals, and a diode across DC lock release terminals to suppress back EMF voltages. Connect components as shown in figures.

Diagrams illustrating back EMF protection for lock releases: Fig. 1A shows a varistor (MOV) for a 12V AC lock release, and Fig. 1B shows a diode (1N4002) for a 12V DC lock release.

Built-in Relays - Back EMF Protection Art. 4800M

The Art. 4800M includes selectable back EMF protection for relays using MOV jumpers. Select NO position for fail-secure locks (C & NO), NC position for fail-open locks (C & NC), or remove the jumper completely to disable protection for gate controllers.

Programming (See Also the Relevant Flow Chart)

Programming Flow Chart:

Programming flow chart for Art. 4800-4800M codelock: Enter Engineer's Code -> Confirm/Change Code -> Set Relay 1 Code & Time -> Set Relay 2 Code & Time -> Set Relay 3 Code & Time -> System Ready. Each step involves ENTER confirmation and melody feedback.

• Enter the "ENGINEER'S CODE": First time, type six "1"s (111111 factory preset), then press “ENTER”. The red LED will illuminate.
• Confirm "ENGINEER'S CODE" (type again) or enter a new 4-8 digit code, then press “ENTER” (Melody). Pressing ENTER twice without changing the code exits programming.
• Enter the code (4-8 digits) to enable "RELAY 1" or re-enter the existing code, then press “ENTER” (Melody).
• Enter the "RELAY 1" operation time (2 digits, 01-99; 05=5 seconds, 00=remain open time) or re-enter existing time, then press “ENTER” (Melody).
• Repeat for "RELAY 2" and "RELAY 3" codes and times.
• The system is ready to use (red LED turns off).

Programming Notes: Press ENTER twice after a command to exit the programming menu.

Return System to Preset Engineer's Factory Code:

• Turn off power to the codelock.
• Keep "ENTER" pressed while turning power back on.
• Release "ENTER". The engineer's code is reset to "111111".

Operation

• Type the programmed code and press "ENTER".
• If correct, the green LED illuminates for approx. 2 seconds, and the relevant relay operates for the programmed time.
• If a wrong code is entered, a continuous melody sounds for 4+ seconds.
• To switch off a relay during operation, type its code then press "CLEAR".

Operation Notes:

• To operate relays together, set the same code for each.
• Incorrect code entry triggers a lockout period (starting at 5 seconds, increasing with each mistake). The system operates only with the correct code.
