VIMAR 885E intercom 4+2 Conductor 2-Family 88TD + 8870, ELVOX Door Entry, Withe

Product Information

Ringtone volume and volume for communicating, brightness, colour and contrast are adjustable. Possibility of choosing between 6 melodies available for selection. ‘Mute’ function

No, kit K40910 does not offer this possibility. For remote management from a smartphone you should opt for K40945. No, the number of cycles cannot be modified, but the volume and melody can be modified (among the 6 available for selection).Elvox Intercom devices are designed to be installed in any environment, thanks to the simplicity of installation and the flexibility of the configuration. In the 1960s, the boom in production prompted frequent moves and changes of production facilities and the opening of a branch in Milan. The possibility of showcasing its innovative products at major tradeshows enabled Elvox to enter foreign markets. Power for the system is present as a constant 24V DC, and the audio is still an old-fashioned analogue signal that we’ll all be familiar with. On that 24V DC though are imposed a series of pulse trains to trigger the different alarms and other functions, and he describes extracting these with an oscilloscope before showing us the circuitry he’s used to send and receive pulses with an Arduino. The bulk of the video is then devoted to the software on the Arduino, which you can also find in a GitHub repository. Control over all video door entry system functions and settings is immediate, thanks to a particularly intuitive scrolling menu. In addition, all alerts are delivered by way of a similarly clear and uncluttered graphic interface.

Ever since Elvox was founded by Orlando Miozzo in 1954, the company has been one of the key players in the intercom and, subsequently, video door entry system sector. Miozzo was an ambitious and intelligent man who was able to exploit his technical knowledge and expertise to launch Elvox onto the market with the determination necessary to cope with the transformation and growth typical of the Italian economy of the mid-1950s.The LCD TFT colour screen offers a magnificently large and well-defined image: 7" with 1024x600 pixel resolution. Cameras / Monitors / Handsets / Entrance Panels & Buttons / Door Releases / Trades Timers / Speaker Units / Power Supplies There was a time when an intercom was simply a pair of boxes with speakers joined by a couple of wires, with an audio amplifier somewhere in the mix. But intercoms have like everything else joined the digital age, so those two wires now carry a load of other functionality as digital signalling. [Aaron Christophel] installs these devices for a living, and has posted a fascinating reverse engineering video that we’ve also placed below the break. At any time, you can adjust the call ringtone volume, talk/listen volume and display brightness, contrast and colour, even during a conversation. The result is an interesting primer for anyone who fancies a bit of serial detective work, even if they don’t have a intercom to hand.
