The INCOM-LTE and INCOM-LTE-WF have the same function, the difference between the two models is their mobile network communication capabilities. While the INCOM-LTE is only capable for GPRS or EDGE connection, the INCOM-LTE-WF uses LTE and WIFI networks (except the 5G protocols). Operation: the communicator (simulating a landline towards the alarm centre) receives Contact ID reports from the alarm panel, forwarding those to the remote monitoring station via the mobile network (in the form of TCP/IP or UDP packets), as it is defined in the SIA DC-09 standard. If it is successful, the acknowledgement received from the monitoring receiver is signalled to the alarm panel. At the same time, it can forward the contact signals received on its own inputs to the monitoring station. The unit will turn itself off if the power supply drops below 10.5V. (battery protection)
