The module can be combined with four flat intercom systems. One main phone number and 1-1 reserve phone number can be given at each flat. The InterCom 4G establishes communication through the GSM/3G/4G network. Hence, the distance is unlimited; we only have to provide a power source to operate the module.

After answering the call, we can control two outputs separately. The device allows us to control a gate and a magnetic door separately, for instance.

Using caller identification, we can manage the output from 1000 phone numbers, while without caller identification, we can activate the output from any number.

The power monitor allows us to send SMS or voice messages during a power outage. A Lithium-polymer battery, equipped with a quick connector, provides continuous operation for even 24 hours.

The module can be combined with 4+n intercom systems, so we can use the particular intercom we want. We have already tested with nine different brands.

Programming is possible by SMS, voice menu, Android (Bluetooth), or PC (USB or Bluetooth) with the ProRead software. The GSM device measures and logs the GSM signal hourly, which can be read and charted. The module can store up to 16,000 events, including the states of the inputs and outputs, power supply resets, GSM network and module state-related information, incoming and outgoing calls, and SMSs.
