What is the Honeywell L3000LB?
The Honeywell L3000LB is a version of a Honeywell L3000 LYNX Plus Security System without an included backup battery. While this version of the L3000 is rarely sold, it can be a good option if you already have a backup battery for the system. The Honeywell L3000LB is not sold by Alarm Grid.
In the name "Honeywell L3000LB", the "LB" stands for "less-battery", indicating that no battery is included with the security system. This is rather odd, as nearly every wireless all-in-one security system is going to include a compatible battery as a common courtesy. But the Honeywell L3000LB does not include a battery. It is designed for customers who, for whatever reason, do not require a backup battery for the system. The most likely scenario is that the end user already has a backup battery. This could be because they have an L3000 System that became damaged, and they only need to replace the panel, not the backup battery.
A wireless panel gets its main power from a wall outlet using a plug-in transformer. But if the electricity goes out, then the panel will be dependent on the backup battery as a backup power source. The backup battery will automatically kick in and begin supplying power as soon as AC power is lost. This could be due to an electrical outage, or perhaps someone unplugged the transformer from the wall or switched the power off at the breaker. No matter the reason, the backup battery can temporarily keep the system running until the AC power is restored.
If you have a Honeywell L3000LB System, then it is strongly advised that you add a compatible backup battery to the panel. The entire lineup of Honeywell LYNX System Batteries is compatible with the Honeywell L3000 and Honeywell L3000LB. These include the Honeywell LYNXRCHKIT-SC Standard Capacity Battery, the Honeywell LYNXRCHKIT-HC High Capacity Battery, and the Honeywell LYNXRCHKIT-SHA Super High Capacity Battery.
