GE Interlogix TX-E251 Product Description:

The GE Interlogix TX-E251 is a wireless long-range door/window sensor with extended battery life. The TX-E251 is a sensor intended for installation on doors, windows, and other objects that open and close. The sensor transmits signals to the GE Interlogix control panel when a magnet mounted near the sensor is moved away from or closer to the sensor. The TX-E251 features a high capacity CR2 lithium battery for extended battery life, and maximum performance output power for long range applications. The sensor features two separate zones: zone 1 can be used for either of the two reed switches, and zone 2 can be used as an external contact option. The sensor is also equipped with a cover tamper switch for additional security.

GE Interlogix TX-E251 Product Mounting:

Included with this device is double sided tape for the transmitter and magnet, as well as screws if a more secure method of mounting is preferred. Choose a suitable location for the sensor ensuring desired signal strength is achieved. Note that it is recommended the transmitter be installed on the stationary or non-moving part of the installation (frame) and the magnet installed on the moving object (door). Where possible, install sensors within 100 ft. (30 m) of the panel. While a transmitter may have an open-air range of 500 ft. (150 m) or more, the environment at the installation site may have a significant effect on operational range. Changing a sensor location may improve wireless communication.

For reliable bonding with the provided double sided tape, ensure the surface is clean and dry. Apply the tape to the backside of the sensor, and then to the desired location. Apply firm pressure for several seconds. When mounting with double sided tape, ensure temperatures are above 50°F and will remain above 50°F for at least 24 hours to ensure proper bond. After 24 hours, the bond will hold at lower temperatures.
