GE Interlogix TX-E121 Product Mounting:


Included with the TX-E121 device is one piece of double sided tape for permanently securing the Command Button in a desired location. Choose a suitable location for the sensor ensuring desired signal strength is achieved. Where possible, install sensors within 100 ft. (30 m) of the panel. While a transmitter may have an openair 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, 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.
