Installation - Alarm.Com ADC-T2000 User Manual

Prepare the wires
Disconnect all of the wires and remove the
existing thermostat. Remember to secure
the wires so they don't fall into the wall.
Follow these guidelines for safe and secure
wire connections:
• Ensure the wires are a proper gauge
between 18-24 AWG.
• Make sure wires have exposed straight ends
about 1⁄8" long.
CAUTION: Verify that the system is 24 VAC.
If the old system is labeled as 120 or 240
volts or has wire nuts, the system is
high voltage. Do not install the thermostat
to a high voltage system. Contact a local
HVAC professional for help.

Install the back plate
Use the bubble level provided on the back plate
as a guide. Mark where the screws will go with
a pencil through the screw holes on the
back plate. Ensure the top of the back plate is
facing up.
If necessary, use the trim plate to cover
up any marks or holes left from the
old thermostat. Attach the trim plate before
securing the back plate to the wall.
Drill holes with a 3⁄16" drill bit to tap in the
drywall anchors for added support
