WARNING: Cancer and Reproductive Harm –


The World's Smallest Wireless Window Security Transmitter

A bulky home security system can be an eyesore. Adding to that stress is hard wire installation permanently altering the aesthetics of your room or window treatment. With its wireless connectivity and fully concealed platform, however, the iON Security Micra is a window security sensor that finally eliminates these pesky inconveniences.

The iON Micra features a window sash sensor that triggers an alarm whenever the contact between it and its corresponding surface mount magnet is severed. The transmitter is powered by a long-life lithium battery that is easily replaceable when a low battery condition is indicated by the control.

Each iON Micra has its own unique identification code (serial number) permanently assigned during manufacturing. The control unit is required to enroll the transmitter's ID during installation of the alarm system.
