LED Details
LED 1 (red)
LED 1 flashes when there is an error. The number
of flashes is the error number. If there are two or
more errors at the same time, the errors will be
flashed one after the other. The LED will stay off
for at least four seconds between errors.
LED 2 (yellow)
LED 2 flashes with every communication between
the module and the host. Normal pattern calls for a
series of quick flashes every two seconds in Idle
Mode or four seconds in PowerSave Mode.
LED 3 (green)
LED 3 flashes with every communication between
the module and its radio unit in Idle mode, and
with every communication with Alarm.com in
Connected Mode. In PowerSave mode, this LED
flashes in unison with LED 2.
LED 4 (green)
LED 4 indicates the GSM signal level as a number
of flashes (0 to 5 bars). The number of bars may
not correspond to the bars shown on your cell
phone. A level of 5 bars is obtained only in the
strongest signal conditions. Signal level is updated
every ten seconds if it fluctuates, or every 30
seconds if it is fairly stable.
If LED 4 is not flashing it indicates one of the
following states:
• The module is in power save mode;
• The module just powered up;

Error and Solution
1
Module cannot communicate with the host.
Perform a power cycle by disconnecting AC
and battery, then reconnecting battery first,
followed by AC power. If this does not fix
the issue, contact Alarm.com Technical
Support.
2
The SIM card is missing. The SIM card
holder can be found on the Module. Verify
that the SIM card holder is closed securely
and that there is a SIM card in the holder.

This displays when the Module is first
registering with the GSM network after
being powered on. If it persists for more
than a few minutes, it means the Module is
unable to register with the GSM network.
Check LED 4 for signal level. If signal level
is lower than 2, change the panel’s location
or use a remote antenna option.

The Module is registered on the GSM
network but cannot connect with
Alarm.com. Contact Alarm.com Technical
Support.

Radio portion of the Module is not working
correctly. If this persists for more than a
few minutes, contact Alarm.com Technical
Support.

This is an error only if it persists for more
than a minute. Otherwise, it’s just an
indication that the Module is fixing an
unusual condition regarding communication
with the GSM network.
