Qolsys QS1431-840 Product Description:


The Qolsys QS1431-840 IQ Glass is glassbreak detector that is specially designed to protect you if an intruder tries to break-in through a window. The IQ Glass acts as a second line of defense against burglary intrusion and works with any S-Line compatible Qolsys IQ control panel. Using our proprietary S-Line encryption technology, encrypts signals sent to the compatible 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' and is activated automatically when you arm your compatible 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.

Product Features:

  • Encrypted S-Line sensor technology protects signals sent to the compatible panel (while still providing support for legacy 319.5 systems)
  • Actively listening for breaking glass frequencies when you are in "stay" or "away" modes
  • Typically installed on the wall opposite the windows needing protection, or on the ceiling in a room with windows on multiple sides
  • Protects widows within line of sight within 25'

I was looking for a glass break sensor because my Alarm system does not have one. After looking at many different options for stick-on glass break sensors I decided on these. Seems to be built well and they are very good value for the peace of mind they provide.
