Essential Info

The PowerCode Magnetic Contact transmitter is designed primarily for use in protecting doors and windows against intrusion. It uses a built-in reed switch that operates in conjunction with a magnet to detect the opening and closing of the door or window it is installed on. When activated, the magnetic contacts initiate an individual 24-bit PowerCode ID message, which identifies it to the target receiver as a separate transmitter. Each ID code is randomly selected from 16 million possible combinations, and is therefore unique and virtually impossible to accidentally reproduce. The Miniature PowerCode Contacts also offer an additional back tamper switch for detecting removal of the device from its place to comply with the latest European EN standards requirements. A smart anti-collision algorithm prevents signal jamming by simultaneous transmission from multiple devices. Periodic transmission of supervision signals is used to confirm system connectivity at all times. The Magenetic Contacts are powered by a long-life, easily replaceable, CR-2 Lithium battery.

    MANTAS -- celbridge, XX   6/16/2012
    Item arrived quickly and at the reasonable cost. However had major problems trying to enroll it into the system. After a lot of frustration ended up phoning Visonic directly hoping to solve the problem. They could not figure out why contacts did not work and agreed to replace them. Fair play to Visonic.
    DAVID -- duncan, OK   6/10/2012
    Works very well. Easy to install, easy to setup.
    ANDREY -- redmond, WA   5/23/2012
    works the way it should
    NORMAN -- dover, MA   3/2/2012
    Received panel and accessories. Received without GSM module SIM card tray (plastic cover that holds card onto module). Called Tech and Visonic to have only tray sent or GSM exchanged (I had worked on panel). Had to send back panel. Received 2nd exchanged panel--it is also missing SIM tray. I have to purchase postal insurance each time I return it--this has cost me time and $.
    CARL -- hollywood, MD   1/12/2012
    I have 17 of these in my house -- they all work without fail.
    WILLIAM -- lakeville, MN   12/11/2011
    Small is beautiful, and these are small. I have a number of them installed already and they work nicely.
    CARL R -- hollywood, MD   12/8/2011
    This is my go-to choice of sensors for my Visonic security system. I have 18 of them so far.
    WILLIAM -- burnsville, MN   11/30/2011
    Have many of these, they all work great.
    WILLIAM -- burnsville, MN   10/31/2011
    Love these little guys. Smaller than the stock units that came with the panel, less noticable but just as effective.
    WLD -- Minnesota   10/18/2011
    Love these little guys! So much nicer looking than those big blocky other ones, easier to install too.
