Description

• Device that allows communication between the cabin and the outside via a GSM telephone line, can be used as a GSM link to convert a digital line (GSM) to analog line to use an intercom of any manufacturer, which only allows analog line, or as a track with our EMBI4 audio and voice device.
• It has a telephone number for voice and an IP for data. The MK-875 supports all GSM/GPRS network carriers, whether CSD, USSD, SMS or, of course, voice. Data can be received via GSM (DTFM and TMDT©), GPRS or the Internet (UDP and TCP/HTTP).
• It supports m2m, which guarantees a direct and simple machine-to-machine communication with a low cost for the user, being able to work with any GSM telephone operator.
• The programming can be done by SMS, in which the parameters that we want to modify will be sent, it is also possible to perform the programming through the free platform Megom OnLine.
• Compatibility with Elecmegom controllers through two RS-485 wires, being able to interact remotely from the Megom OnLine platform, this connection will allow you to perform telemetry, telemetry and programming on your controller, with a minimum cost due to the optimization of the communications protocol used.
• Up to 4 elevators with 4 EMBI_v4 devices and a single MK-875 track, can be connected through a single GSM line, using CAN to perform communications between EMBI_v4 in each cabin and the MK-875 placed in one of the machine rooms, ensuring data management processes and audio quality.
• 12Vdc power supply (range 10Vdc-30Vdc) required for external power supply and power supply in case of power failure, the MK-875 module includes an external battery status monitor, sending a message to the maintenance company when it is not at an optimal charge level, the battery is recommended to be of a minimum capacity of 600mA/h.
• It incorporates a field meter to check the coverage at all times and install the module in the location with the best signal.
• With the new megom OnLine platform, you will be able to perform the periodic tests required by the EN 81.28 standard, having a database with all the details about the tests, reports of malfunctions or battery in bad condition, this history can be exported to a file with which you can create your own reports.
