Simon XT Radio Installation: Overview with Video

How do I install the new radio for the Simon XT Control Panel?

For instructions on how to replace your old radio watch the video or click the step-by-step guide below.


Tools and supplies needed

  • New LTE radio with thin antenna attached

  • Thick antenna (included, but not attached)

  • Small Phillips-head screwdriver (not included)


Disconnect battery wires

Unplug the AC power cord from the wall and disconnect the red battery wires coming out from the bottom left of the panel. Twist and pull on either end of the thick plastic section where they meet to disconnect.

If you have tucked those wires inside your panel, disconnect them after step 2.


Open the panel

Open the panel by pressing the two tabs on the top of the XT – seen below


Remove old radio

The radio is located in the “module compartment” (see image). Use your screwdriver to remove the two screws in opposite corners on the old radio and set them aside.

To remove the old radio from the “module compartment”, slide the screwdriver in the narrow channel by the phone jack to reach under the lip of the radio and pry up. See image below.


Plug in the antenna

Plug the new antenna into the gold connector closest to the outer edge, by lining up the opening of the gold connector with the new antenna, and pinching until it snaps into place (as shown in the images below).


Attach new radio

Slide the new radio in place under the two plastic tabs at the top of the module compartment first and press on the opposite end gently until the connector pins are in place. The plastic tabs are circled in orange in the above image.

Screw the radio into place using the screws from the previous radio.


Position antennas

Position the antennas inside of the panel box as shown below. If needed, adhesive may be used on the slimmer antenna, but not on the thicker antenna.


Close the panel

Close the panel, ensuring that:

  • The red battery wires are routed through the same hole as the power cord.

  • The front and back halves of the panel are properly lined up on its hinges. If your panel won’t close at the top, ensure that neither antenna wires are resting on the corner that divides the radio from the rest of the panel.


Re-connect battery wires

Re-connect the red battery wires together, then plug the panel into the wall and wait a few minutes for the system to power up.
