7845i Internet Communications Module
7845i is the subscriber end of the AlarmNet-i reporting system. It is comparable to a digital communicator or long-range radio, but instead of transmitting signals over telephone lines or radio waves, it transmits alarm and status messages to the central monitoring station using a secure broadband Internet connection.
Using the ECP keypad bus, the 7845i sends status messages such as tamper and network communication failures to the control panel. ECP also provides Contact ID for messages being sent to the central station.
