Interlogix TX-E721 - Data Sheet

Designed for use with Interlogix control panels and wireless
receivers, the TX-E721 Passive Infrared (PIR) Motion Detection
Sensor is a wireless, battery-powered device that provides
outstanding performance. Featuring advanced signal processing,
this 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
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 control panel.
