Do the Honeywell Lynx Systems Require RF Line of Sight?

No, Honeywell Lynx systems do not require line of sight. RF communication does not utilize line of sight. Lynx panels use RF communication to interact with 5800 Series wireless devices, such as the 5800CO and the 5808W3. Direct line of sight is not used when interacting with these devices.

The typical range of a 5800 Series wireless device is roughly 200 feet. However, this range might be reduced due to the presence of obstructions, such as walls, floors, ceilings and various metal objects. In order to extend this range, a user can add a 5800RP wireless repeater to their system. By using this repeater, the range between a 5800 Series wireless device and the Lynx panel can be extended up to a maximum distance of about 400 feet. A 5800RP should be added to the security system so that the device receives zone supervision.

Honeywell Lynx systems use RF communication to interact with security and life-safety devices. When communicating with home automation devices, Z-Wave communication is used instead. In order to use Z-Wave communication, an L5100 Z-Wave controller will need to be installed into the Lynx panel. Once installed, an L5210 system will be able to support up to 3 Z-Wave thermostats, 4 Z-Wave door locks and 40 Z-Wave light modules. Meanwhile, an L7000 panel will have the capability of supporting a maximum of 4 Z-Wave thermostats, 6 Z-Wave door locks and 40 Z-Wave light modules.

The L5100 Z-Wave controller itself will provide the panel with support for up to 20 Z-Wave scenes, 20 rules and 20 different schedules. An additional 20 Z-Wave scenes will be available once the system has been synced with Total Connect, for a total of 40 different possible Z-Wave scenes. Users should be aware that any scene that has been programmed locally will not be able to be changed using Total Connect. However, the panel can display any Z-Wave scene that was created on Total Connect by performing an automation sync from Total Connect.

After the L5100 Z-Wave controller has been installed, users will need to program Z-Wave devices into their Lynx system.
