Slimline Wireless Magnetic Door & Window Contact for use on the Ultralarm Wireless 3G GSM Alarm.

The Wireless Transmission range between the Magnetic Contact and Solar or Battery Sirens is 450 ft (line of sight), which equates to around 150 - 240 ft in most applications.

It is powered by 2 x 3v CR2032 Batteries, which will last at least a year in most applications, in many applications far longer, you will get a SMS notification should the batteries get low.

The Magnetic Contact and Magnet need to be Installed onto a Door/Window and Frame in such a position that when the Door/Window is closed the gap is no more than .5". There is an arrow on both parts which need to be lined up during Installation. You will see a small Red LED on the Magnetic Switch when the Door/Window is opened if you have installed correctly. They are fitted using the double-sided tape (supplied).
