Is the L5210 Better than the L7000?

No, the L5210 is not better than the L7000. The L5210 has fewer system zones and a smaller touchscreen than the L7000. The L7000 can do nearly everything the L5210 can, so the L5210 offers no real advantage. The only thing the L5210 can do that the L700 cannot is use a POTS connection.

The Honeywell L5210 and the Honeywell L7000 are both part of the Honeywell LYNX Touch Series. These are the two newest systems from the LYNX Touch lineup, and they offer virtually the same functions and features. They use the same wireless sensors, and they support the same WIFI communicator. They also support the same Z-Wave controller module and the same Verizon LTE Communicator with firmware version 9 or higher. Programming the two systems follows the same process, and the menus look virtually identical.

At the end of the day, the L7000 is more robust than the L5210. The L7000 supports 79 wireless zones, while the L5210 only supports 63. The L7000 supports 24 key fob zones, while the L5210 only supports 16. The L7000 supports 48 user codes, while the L5210 only supports 32. The L7000 has a 7 inch touchscreen, while the L5210 only has a 4.3 inch touchscreen. Long story short, the L5210 and the L7000 are the same systems, but the L7000 offers a little bit more.

There is one thing the L5210 has that the L7000 does not. That is the ability to support a phone line connection. The L5210 can dial out and contact a central monitoring station during alarm events. To do this, an RJ31X jack is needed. This is necessary for seizing the phone line so that the system can dial out. But while the L5210 can be used in this way, the L7000 cannot. This difference is a relatively minor detail, as using a phone line connection is strongly discouraged.

Not only is POTS (plain old telephone service) communication slow, it is also unreliable, as the signals often fail to reach their intended destinations. POTS connectivity also makes it impossible to use the Total Connect 2.0 Service for remote panel access. Instead, it is much better to use an internet and/or cellular communication path.
