Will 2GIG Sensors Work On an Interlogix Simon XTi or XTi-5?

No, 2GIG Sensors will not work on an Interlogix Simon XTi or XTi-5. The 2GIG sensors operate at a wireless frequency of 345 MHz. This frequency is incompatible with the Simon XTi and XTi-5. Instead, these alarm systems accept wireless signals that operate at the 319.5 MHz frequency.

An alarm system is able to accept incoming signals from wireless sensors using a wireless receiver. Nearly every all-in-one wireless alarm system comes with an integrated wireless receiver for this purpose. The wireless receiver for the Simon XTi and XTi-5 Systems is designed to receive signals at a frequency of 319.5 MHz. This means that these systems cannot function with the 345 MHz 2GIG Sensors, unless a third-party converter is used.

Since 2GIG Sensors operate at the 345 MHz frequency, they are very similar to the Honeywell 5800 Series Sensors. The 5800 Series Sensors also communicate at the 345 MHz frequency. However, the compatibility for these sensors is not the same, due to advanced level communication lockouts. The 2GIG Sensors can be used with the 2GIG GC3, the 2GIG GC2 and the Honeywell Lyric Controller. Meanwhile, the 5800 Series Sensors will work with any of these systems, as well as the Honeywell LYNX Touch Panels and any Honeywell VISTA Panel that has an added wireless receiver.

However, the Simon XTi and XTi-5 Systems look for signals at a frequency of 319.5 MHz. Some sensors that operate at this frequency include the Interlogix Sensors and the Qolsys Sensors. But for the Qolsys S-Line sensors that utilize encryption, the encryption features will not be enabled when they are used with an Interlogix Alarm System. Additionally, Interlogix Sensors may also be sold and traded under the GE brand. Both Interlogix and GE Sensors can be used with the Qolsys Systems, including the Qolsys IQ Panel 2. This is because Qolsys Systems also communicate with wireless sensors at the 319.5 MHz frequency.
