The Interlogix TX-E401 is a wireless overhead garage door "tilt" sensor. The device is installed at the top center on the interior of a garage door. When the garage door is opened, the sensor moves from a vertical to a horizontal position. The integrated 45 degree "ball sensor" will fault after the door starts traveling horizontally on the overhead tracks. Once this happens, the sensor will send a fault signal to the alarm system to let it know about the opened garage door. The panel will then perform a predetermined action based on the programming settings for that wireless zone. The device operates at a wireless frequency of 319.5 MHz, making it compatible with any Simon XT, XTi and XTi-5 System.
Unlike normal entry doors that are normally protected and monitored some garage doors can be configured as monitor only zones. This means that they will not trigger an alarm when faulted if the system arms. Instead the fault can generate automated alerts from the Alarm.com app each time the door is opened, closed or left open for a set period of time. Since the TX-E401 operates based on tilt, there is no need to align a magnet with the sensor. This can be particularly difficult in a garage environment in terms of dealing with the wider spacing between the overhead door and the door frame as well as the large , bulky metal rails which can cause interference issues. Also, other indoor door contacts may not have the versatile 32F to 120F degrees operating temperature range. All in all, tilt sensor are the best way to protect a garage overhead door. When the garage door is closed, the sensor should be at a 90-degree angle. As soon as the sensor is tilted to a 45-degree angle due to the garage door being opened, the sensor will issue the fault. Once the the sensor is returned to a 90-degree angle, the fault will automatically restore.
A user can easily adjust the sensitivity of the TX-E401 sensor to have it respond based on the design of their garage door. The device also features a "slow loop response" that only allows the sensor to activate when the garage door is fully opened. This makes it impossible for other factors such as the wind or an object hitting against the garage door to activate the sensor and cause a false alarm. To protect the TX-E401 from being tampered with, a case tamper is featured on the sensor. If the device is opened up for any reason, a trouble condition will be displayed on the panel display and reported if the system is monitored. If this occurs while the system is armed, an alarm event will immediately go into effect.
On average, the battery used with the TX-E401 will last for five years before requiring a replacement. When it is time to replace the battery, any lithium CR123A battery can be used with the sensor. In open air, the TX-E401 will function from up to 500 feet away from the panel. However, we recommend using it within 100 feet from the panel for optimal performance.
