The 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 backwards compatibility for legacy 319.5 systems. Triggered by the pitch and frequency of breaking glass, the IQ Glass is effective within 25-² and is activated automatically when you arm your IQ Panel in either -œStay- or -œAway- mode. Typically installed on the opposite wall or on the ceiling to allow for better -œlistening- ability in large living areas.
