GE Interlogix TX-E721 Product Description:


The GE Interlogix TX-E721 is a indoor, battery-operated, wireless, pet-immune PIR motion detector. The TX-E721 motion detector is compatible for use with GE Interlogix control panels and wireless receivers. Featuring advanced signal processing, the TX-E721 detection device is capable of eliminating false alarms caused by pets weighing up to 40 pounds.

Well suited for both homes and small to mid-sized businesses, the TX-E721 motion detector identifies the movement of a person within a specific area by sensing the infrared energy emitted from a body as it moves across the sensor's field of view. When this motion is detected, the sensor transmits an alarm signal to the GE Interlogix control panel.

Product Features:

  • 35 ft. x 40 ft. detection coverage with selectable sensitivity
  • Pet immunity signal processing prevents false alarms for homeowners with pets weighing up to 40 lbs.
  • 5-year battery life with an easily replaceable CR-123 battery
  • Low battery reporting indicates when batteries need replacing before they expire
  • Cover tamper switch detects potential disablement or damage to a sensor by an intruder
  • Fully supervised device sends signal every 64 minutes to the security panel to ensure uninterrupted performance
  • ETL Listed

GE Interlogix TX-E721 Product Installation:


  • Temporarily place the sensor in its intended mounting location. Program and final test the sensor before permanently mounting it.
  • If possible, locate sensors within 100 ft. (30.5 m) of the panel. While a transmitter may have a range of 500 ft. (152 m) or more out in the open, the environment at the installation site can have a significant effect on transmitter range. Sometimes a change in sensor location can help overcome adverse wireless conditions.
  • The recommended mounting height is 7 1/2 ft.
  • Position the sensor to protect an area where an intruder would be most likely to walk across the detection pattern.
  • Mount the motion sensor on a rigid surface which is free from vibrations.
  • Do not mount the sensor near duct work or other large metallic surfaces which may affect the RF signals. Actual acceptable transmitter range should be verified for each installation.
  • Mount the sensor permanently on a flat wall or in a corner. Do not set it on a shelf.
  • Windows should be closed in any area which has an armed motion sensor.
  • The sensor must be incline-mounted at a mounting height of 7.5 ft.
