The EcolinkTX-E401 Garage Door Tilt Sensor from Interlogix® provides intrusion detection for garage structures. This sensor can be mounted on top of any garage door and allows for quick and easy installation without the need to align a magnet.
Was using a regular door/window 2 piece stick on sensor but it kept moving because of where I installed it on the frame of the sliding door. The Tilt sensor is one piece and mounts right to the door. Very easy to install and register to alarm system.
