The TX-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. The TX-E401 will transmit an open and close signal to the panel each time the garage door is opened or closed. When the alarm panel is armed, if the garage door opens to a forty-five degree angle, the sensor goes into an alarm condition that turns on the siren and initiates a call to the central monitoring station. The Garage Door Tilt Sensor also features a slow loop response which eliminates false alarms triggered by garage door movement due to wind.
