Qolsys QS1431-840 IQ Glassbreak Detector




Encrypted S-Line technology. Protects widows within line of sight within 25ft. MC12

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 20' 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.
