IQ Tilt-S Encrypted Tilt Sensor


The Qolsys QS1131-840 is a IQ Tilt-S garage door sensor designed with S-Line encryption, to detect the opening and closing of an overhead garage door. You know that sinking feeling when you return home and see your garage door open? As an easy entrance into your home you keep a lot of valuable things in your garage. From cars to tools, sports equipment to freezers full of food, there might more value in the garage than the rest of the house combined. Know when its open with the IQ Tilt-S, a simple, encrypted, device that tells your panel whether the overhead garage door is open or closed, and since your panel is connected to your account, you’ll be able to see the current status of your garage door at any time from your mobile device or computer.


  • Encrypted S-Line sensor technology protects signals sent to the IQ Panel while still providing support for legacy 319.5 systems
