Translates the TIP/RING landline communication of the alarm systems, forwards it to the monitoring receivers, as it is defined in the SIA DC-09 standard. The data transfer is done in the GPRS system of the mobile network, in the form of TCP/IP or UDP packets. Only the CONTACT ID format reporting codes, can be interpreted and forwarded to monitoring, by the device.
Operation:
The communicator (simulating a landline towards the alarm system receives) the Contact ID report codes from the alarm panel, translates it to an IP packet, then forwards it to the monitoring receiver over the GPRS network. The monitoring receiver returns an acknowledgement signal (ACK) to the communicator, upon receipt of the event, which in turn translates the acknowledgement (Kissoff) and forwards it to the alarm panel. In the same time it can send the contact inputs events, to the monitoring station.
