Essential Info

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 window sash sensor triggers an alarm whenever the contact between it and its corresponding surface mount magnet is severed.

Also available for GE wireless receivers. Please see the 3/4" Forstener bit, recommended for installation. For windows with large gaps this product may require the extra strength magnet.

Smarthome does not accept defective returns for this product. You will need to contact the Manufacturer (or Supplier) directly for all warranty issues.


More Info

Installing the product requires just three tools:

1. Drill
2. 3/4" Forstener bit
3. 1/4" wood bit (for antenna insertion

Drilling a single hole about 3" down from the inside top corner of the window mainframe, you merely place and set the Micra antenna & transmitter (in that order) within the cored opening before covering with the system's Surface Mount Magnet, ensuring the product is concealed. That's it!

From then on your fear of any burglars spotting your motion sensors and finding alternate and less-secure entryways into your home or commercial space can be forgotten, because this 3 step easy-to-install package is not only virtually invisible to the naked eye, but it uses a sophisticated wireless transmit that extends to 500 ft of the wireless receiver - making it an ideal choice for installing in just about any corner of your home or office.

The iON Security Micra sensor's battery-life is another one of its convenient features, as its 3.0V Lithium Coin Cell Battery has an average life-span of about 5+ years, ensuring you and your family's safety will not be compromised by the vexing and easily forgettable task of constantly having to replace your battery.
