Honeywell Home 7847i-L Alarm Communicator:


The Honeywell AlarmNet 7847i-L is a broadband internet alarm communicator designed for the Honeywell LYNX Plus L3000 wireless alarm control panel. The 7847i-L fits right inside the LYNX Plus wireless alarm control panel (L3000), providing an easy streamlined installation for those customers looking to have their security system monitored over the Internet instead of a traditional phone line. All that is required is a broadband Internet connection plugged into the 7847i-L. The Internet communicator is designed for true "plug-and-play" capability. No technical router setup is required.

Once installed, your LYNX wireless security system will deliver all alarm signals through the 7847i-L Internet communicator to Honeywell's AlarmNet Network Control Center, which automatically and immediately routes the information to GeoArm's Central Station. The state of the art AlarmNet Network Control Center is fully redundant and monitored 24/7. AlarmNet has the ability to route messages using AlarmNet-i and 800 PLUS services, providing true redundancy and multi-path message delivery.
