Qolsys QS1131-840 Product Description:


The Qolsys QS1131-840 is a IQ Tilt-S garage door sensor designed to detect the opening and closing of an overhead garage door. The IQ Tilt-S garage sensor works with any S-Line compatible Qolsys IQ control panel.

Do 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 it's 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 alarm.com account, you'll be able to see the current status of your garage door at any time from your mobile device or computer.

Product Features:

  • Encrypted S-Line sensor technology protects signals sent to the compatible panel (while still providing support for legacy 319.5 systems)
  • Detects whether door is open or closed
  • Receive a text message if the garage is left open when you leave your house
  • View whether your garage is open or closed from wherever you are
  • Receive a text message if you drive away from your home and your garage is open or closed

I tried the Other brands and they kept shutting offline and not telling me when the door was open. But these ones work perfectly in every spot and communicate perfectly with smart things.

It has been fun to use this product to follow the coming and going of my six kids because I have set each device to alert me when a door either opens or closes. Now I also know when the doors get left open!

The garage sensor provides me great comfort to know at any time that my garage door is either open or closed. Installation was very simple and pairing it up to the app was super simple. Great price!
