Alarm.Com Flex IO Installation Manual page 5

DC power requirements
In addition to battery power, the Flex IO can be powered with
a DC converter. DC power is required for relay installations
due to increased power demands.
DC power is optional for reed switch or input installations.
Anything from 6 to 15 VDC is acceptable. A minimum of 1 A
is required. When using DC power, we recommend installing
batteries for backup power to prevent damage in case
of a sudden power loss.
Cellular signal strength
Prior to mounting, check the cellular signal
strength using the following steps:
❶
Using a screwdriver, remove the battery door and temporarily
insert batteries. Leave the battery cover off. The device LED
should now be active.
❷
Hold the Flex IO in the desired installation location.
❸
Using a paper clip, push the diagnostic button, then release.
The device LED should now be solid red. TIP: Don't have a
paper clip? You can use the optional resistor included in
the box.
Once diagnostic mode is initiated, the LED will display the
cell signal strength in a continuous loop for 2 minutes based
on the patterns on the next page. It may take up to 30 seconds
for the signal strength to be acquired.
