Frequently asked questions about door entry systems and video door entry systems

At Tegui Distel, we help you identify the right equipment for your installation. These answers guide product selection; they do not replace a technical check of the system or the manufacturer's instructions. Tegui and BTicino are different brands: we identify each item by its brand, model, and reference.

Identification and replacement

What information do you need to assess a replacement part?

Provide the exact reference of the current monitor or door phone. If possible, include the references of the entrance panel and power supply, one photograph of the label, and another of the connections, without tampering with the equipment. Also indicate whether there are multiple access points or indoor units. Avoid sending unnecessary personal data.

Will any two-wire door phone or monitor work?

Compatibility must not be assumed based solely on the number of wires. The system, equipment, and configuration must be checked before purchasing a replacement part. Do not change connections based solely on the conductor colours.

I have a Swing 374455. Which model can I install in its place?

Before proposing a replacement, we need to review the installation and its configuration. Provide the references of the entrance panel and power supply, and indicate whether you have multiple access doors or monitors at home. We cannot confirm a direct replacement based solely on the monitor reference.

Where can I find the reference if I only know the range name?

Look for the reference in the documentation or on a label that can be accessed without dismantling or tampering with the equipment. A front photograph can help identify it, but the appearance or range name alone is not enough to confirm a replacement part. If the label is behind the equipment, ask a professional to check it safely.

Can I buy a wall mount because it looks the same as the old one?

We do not recommend choosing it based solely on its appearance. We need the equipment and support reference, or photographs and measurements taken without tampering with the connections. Mechanical compatibility and replacement part availability must be checked before purchasing.

Can I replace only the monitor in a communal installation?

The equipment and the communal system must be assessed. Do not assume that the entire installation needs to be replaced or that replacing only the indoor unit will be enough. The decision depends on the existing references, wiring diagram, and configuration.

Extensions and mobile connection

Can I add a second monitor in a duplex?

The existing system must be assessed. Indicate the model, the planned distance, and whether it belongs to a communal installation. The power supply, number of indoor units, configuration, and line termination must be checked against the system documentation by a qualified installer.

Can I add Wi-Fi and open two doors from my mobile phone?

It depends on the monitor and the configuration of the entrance panels and locks. Indicate how you currently open each access point and the references of the devices. We cannot guarantee opening both access points from an app without reviewing the installation.

My video door entry system has lost Wi-Fi or does not recognize the QR code. What information should I provide?

Provide the exact monitor reference, the name of the app, and whether you have changed your router or internet provider. The procedure should be checked in the model's manual. Do not perform a factory reset before checking its consequences and the corresponding procedure.

Which app should I use with my video door entry system?

Consult the documentation for the exact reference. We do not recommend an app based solely on the brand or the name Classe 100 or Classe 300. Indicate the model and the app you use so we can determine the appropriate procedure.

Does hands-free mean that I can answer from my mobile phone?

No. In the models described here, hands-free means that you can converse from the indoor station without picking up a handset. Mobile-phone connectivity is a different feature that must be checked for the specific reference.

Can I install an additional doorbell?

It depends on the model and the connections supported by its system. Indicate the reference of the monitor or intercom handset and where you need to hear the call. Before recommending a doorbell, actuator, or second indoor station, we must check the technical documentation.

Can you confirm compatibility with Ring or another third-party accessory?

It should not be assumed simply because calling or door release works. Provide the exact references of both devices and also consult the accessory manufacturer. We do not recommend changing terminals, resistors, or making adaptations without compatibility documentation.

Faults

The monitor does not ring and shows no image. Do I need to replace it?

These symptoms alone do not confirm that the monitor is faulty. Indicate its reference, whether any indicator is lit, whether door release works, and whether other residents are affected. A professional should check the power supply, connections, and configuration before recommending a replacement.

What information is helpful if I cannot hear the visitor or they cannot hear me?

Indicate whether the sound fails in one direction or both, whether calling and door release work, and whether the problem affects other residents or began after a modification. We cannot diagnose a faulty component based on these symptoms alone; the system must be inspected.

Questions about specific models

Is the Tegui Serie 8 374494 hands-free?

No. It uses a handset and has a 4.3-inch color screen. It is a 2-wire monitor with surface mounting and a supplied metal base. Its dimensions are 200 × 200 × 21 mm, width × height × depth. Compatibility must be checked before replacing another device.

How is the Tegui Classe 100V16B 374511 installed?

It supports surface mounting with the supplied bracket. It is hands-free, has a 5-inch color LCD screen, and measures 164 × 165 × 20.5 mm. The configuration must be adjusted to the installation; it should not be presented as a universal replacement.

What features does the Tegui Classe 100V16E 374521 have?

It is a 2-wire hands-free monitor with a 5-inch color LCD screen and teleloop. It has two physical buttons and seven capacitive keys, with functions subject to configuration. It measures 164 × 165 × 20.5 mm and supports surface mounting with the supplied bracket.

What is the difference between the 374511 and the 374521?

Both have a 5-inch color screen and hands-free communication. The 374521 Classe 100V16E includes a teleloop and four additional configurable keys compared with the 374511 Classe 100V16B. The choice also requires checking compatibility and the functions supported by your installation.

Can the BTicino Classe 100A16E 344282 show the visitor?

No. It is a hands-free indoor audio unit without a screen. It measures 102 × 155 × 19 mm and supports surface mounting with the supplied bracket. It requires physical configuration and should not be recommended as a video monitor.

Are these four products complete kits?

No. References 374494, 374511, and 374521 correspond to indoor monitors, while 344282 is an indoor audio handset. They do not include a complete installation with an entrance panel and power supply. Always check the contents of the product page before ordering materials.

What does the professional study function of the 374521 do?

Depending on its configuration, it allows the associated lock to be opened automatically when a call is received from the entrance panel. This does not simply mean muting the ringtone. Its activation and use must be reviewed with the manual and the professional responsible for the installation.
