Interlogix has been highly respected in the alarm industry for many years. They are known for offering reliable control panels and sensors for users on a budget. Their systems provide all of the necessary tools for alarm monitoring, just without some of the bells and whistles that you would only find on higher end systems. The Interlogix Panels are great for anyone who just wants a strong, trustworthy security system they can count on, and doesn't require anything super fancy.

While it's true that we view the Interlogix Simon XTi-5i as more of a "budget" alarm panel, that doesn't mean it lacks some impressive features. Starting with the controls, the entire system is operated through a sleek and crisp 5-inch touchscreen display. The menu icons are large and clearly identifiable so that you will have no trouble performing various system actions. The touchscreen controls are nice and response to ensure that you can easily operate your system as you need.

What's even more exciting is that you can adjust the user interface (UI) by selecting from a variety of different color schemes. Not many panels offer this type of feature, and it's great to see Interlogix making their system more visually appealing by offering such customization. The standard practice is to have the system match the color scheme (orange and white). This will have the panel match what you see when you control your system from

Most communicators offer built-in Z-Wave Plus control, thereby allowing you to start establishing your smart home automation network.

The Interlogix Simon XTi-5i actually supports all of the same communicators used with the older Simon XT, Simon XTi, and Simon XTi-5 Systems. For best results, you should use a communicator with LTE functionality. We recommend using one of the following communicators with the Simon XTi-5i System:

Turning to more security-based offerings, the Interlogix Simon XTi-5i has exactly what you need to keep your home or business nice and secure. The system supports up to 80 wireless zones, which is perfect for medium-sized homes and smaller businesses. Most users do not need support for hundreds of zones. The 80-zone support for the XTi-5i is perfectly suitable in most cases, without being overkill. You can also use two (2) hardwired zones with the system, but these will still cut into the 80 zones. for normally closed (NC) contacts only.

When it comes to sensor support, you have many selections to choose from for the Interlogix Simon XTi-5i. The system supports the widely used 319.5 MHz frequency, which has been made popular by Interlogix and Qolsys throughout the years. You can use any of the legacy Interlogix and Qolsys 319.5 MHz Sensors with the system. You can also use the Qolsys S-Line Sensors, but they won't utilize rolling code encryption on the XTi-5i. However, Interlogix is expected to release their own lineup of encrypted sensors that will utilize encryption with the XTi-5i System.
