How to get the Simon XT Up and Running

Installation is ‘relatively easy’ for most people. As the system is mainly wireless. There is no professional installation, although some sellers may offer professional installation service if needed. Out of the box, the Simon XT is a Do It Yourself installation security kit which should be successfully installed within 30 minutes.

The tricky part however, is running the power code down to the outlet.  This typically requires a certified technician (for electrical purposes and safety) to do it.  You also need the right tools.  This is needed if you are mounting it on the wall.  If you are going to set it up in a closet where the cord will be not need to be hidden then plan on doing it by yourself.


Depending on need the Simon XT comes in a variety of packages, most notable of them is the starter package and the deluxe package. The starter package offers the Simon XT package, rechargeable battery, power pack but with no sensor which sets it apart from the deluxe package which comes with a number of sensors.

If you take a look at Protect America who uses this security system still to date, you will see they vary pricing from $19.99 to $49.99/mo.  You can get a second touch screen GE panel and then put Simon XT (which is bulkier) in a closet or hidden spot.  Key fobs still integrate with either panel and with the touchscreen it is more appealing and can still enter the keycode to turn on and off.


The Simon XT security systems have been around for a while and still, makes for a complete and affordable home security system. There is an upgrade to the Simon XT Security called the Simon XTi yet the XT Security system continues to be a preferred choice among home and home security authorized dealers.
