Tilt Sensor For Your Garage Door

Eliminate your uncertainty on whether your garage door is open or closed with the Qolsys IQ Wireless S-Line Garage Tilt Sensor. Simply install this wireless, battery-powered tilt sensor on your garage door, and when the door opens or closes, the sensor will alert you!

  • Detects open/closed status of garage door
  • Battery-powered, no wiring required
  • Provides low battery alerts
  • Wireless range up to 600 feet
  • Built-in S-Line encryption technology
  • Compatible with 319.5 MHz wireless panels, such as GE/Interlogix or Qolsys IQ

The tilt sensor is designed with a cylinder and metal bearing. When the garage door is opened (sensor is tilted), the bearing rolls down the cylinder away from the metal contacts. This disconnects a circuit and sends a signal to the panel saying that the garage has been opened.

Compatibility & Installation

The Qolsys IQ Wireless S-Line Garage Tilt Sensor can be used with any compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.) or a Qolsys IQ Panel. The sensor easily mounts to the top panel (or near the top) of your garage door using the included double-sided tape. When the garage door opens/closes, the sensor will detect the tilt and signal the hub or console.

About S-Line Encryption

Qolsys wireless devices that feature S-Line ("Secure Line") technology offer advanced encryption to safeguard your wireless signals against hacking.

The technology employs an advanced encryption scheme between the wireless sensor/device and the control panel to ensure that wireless event transmissions are always unique, preventing and eliminating common replay attacks (when an unscrupulous person uses an easy-to-purchase software-defined radio or "listening device" to replay events that were previously sent by wireless devices paired with a security system.) At time of pairing, S-Line technology passes a unique key which enables the encryption algorithm for unique event transmissions, thereby preventing such replay attacks.
