LED details
LED L1 (red)
L1 flashes when there is a general error or an error on the cellular path. The number of flashes indicates the
error number. If there are two or more errors at the same time, the errors will flash one after the other. The
LED will stay off for at least four seconds between errors.

flashes
Module cannot communicate with the panel. Ensure section [382] option [5] is ON. Verify panel
1
software is version 1.1 or higher. Check the connectors (between the panel and communicator) and
powercycle the panel. If the error persists, there may be an issue with the module or panel.
The SIM card is missing. The SIM card holder can be found on the module. Verify that the SIM card
2
holder is closed securely and that there is a SIM card in the holder.
The module is trying to register on the LTE network. If it persists for more than a few minutes, the
module is having problems registering with the LTE network. Check L4 for signal level. If signal level
3
is lower than 2 "bars", change the panel's location or use a remote antenna option. If the signal is
good, the module may be roaming on a LTE network that does not partner with our LTE providers, or
the SIM card was not activated yet because the Alarm.com account was not created correctly.
