In the IQ Glass-S installation manual you will find step by step instructions in order to complete the job such as choosing the best installation location, securing to surface, removing the cover, removing battery tab, replacing the face plate, learning into IQ Panels and more.

The Qolsys IQ Glass is specially designed to protect you if an intruder tries to break-in through a window. Using our proprietary S-Line encryption technology encrypts signals sent to the IQ Panel while still providing backward compatibility for legacy 319.5 systems. Triggered by the pitch and frequency of breaking glass, the IQ Glass is effective within 25′ and is activated automatically when you arm your IQ Panel in either “Stay” or “Away” mode.  Typically installed on the opposite wall or on the ceiling to allow for better “listening” ability in large living areas.
