The T4000 Lite is fully packed with the features of the original T4000 Security Communicator, with a smaller price tag it is the ideal solution for installations where the T4000 is being powered from an existing battery-backed alarm system.   The T4000 lite is compatible with most alarm panels and simply connects to the panel via its telephone port, eliminating the need for a dedicated alarm panel phone line connection to the street.  The T4000 Lite handles all alarm  communications via its Ultra-fast 3G dual SIM and 10/100 Mbps Ethernet polled communications paths.
