Why Is My Honeywell L7000 Restarting Again and Again?

Your Honeywell L7000 is restarting again and again because its L5100-WIFI Communicator is having trouble connecting with a network. When the module tries and fails to connect to a network while the system is starting up, the system will reboot and try again, thus creating an endless cycle.

Power down your panel by disconnecting its backup battery and unplugging its transformer. You will need to open up the panel to access its backup battery. You can keep the panel open, as you will need to disconnect the L5100-WIFI module once the system is completely powered down. With the module removed, reconnect the transformer to power the system back on. If the panel boots up successfully with the L5100-WIFI module removed, then that was the cause of the problem.

The most common reason why an L5100-WIFI module will cause an endless boot-cycle is because the system is being used with a managed IP network that uses Static (fixed) IP addresses. We recommend configuring the L7000 System with DHCP (Dynamic Host Configuration Protocol) for automatically assigned IP addressing. This will make it easier for your L7000 System to successfully connect with an IP network so that the boot-loop issue does not occur. Many users trying to configure a Static IP address will enter some incorrect information when adjusting the network settings. The system will then fail to connect, and the boot-loop cycle will occur.

In order to fix the problem, it is necessary to adjust the communication settings on the panel. Unfortunately, you won't be able to do this with the system in a constant boot-loop. And you also cannot access the communication settings without a communicator installed. As a result, you will need to have a cellular communicator installed inside the panel. Both the Honeywell LTE-L57A and Honeywell LTE-L57V are great options, provided that your L7000 is running a high enough firmware version.

Once you have a proper communicator installed that isn't causing a boot-cycle, you can perform a factory reset for the panel's communication settings. To do this, choose Security > More > Tools > Installer Code (default 4112) > Program > Comm Diagnostics > down arrow > Setup Communication > Factory Defaults.

After performing the default for the panel's communication settings, you can then power the system back down by disconnecting the backup battery and unplugging its transformer. Then re-install the Honeywell L5100-WIFI module you were using before. If you are still experiencing a boot-cycle issue, then you should contact your alarm monitoring company for further assistance.
