The Qolsys QS1131-840 is a simple S-Line encrypted IQ Tilt-S garage door sensor designed to detect the opening and closing of an overhead garage door. When triggered, the tilt sensor sends a signal to the panel saying that the garage has been opened, and because your panel is linked to your alarm.com account, you'll be able to monitor the current status of your garage door at any time from your mobile device or computer.

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 automobiles to tools, sporting equipment to food freezers, the garage may be worth more than the rest of the home combined.

NOTE: Improper orientation and/or placement of the bearing cylinder may result in false alarms or incorrect signal.
