    Just ran across an older system that has pull-apart contacts on all
    operable windows. The contact is glued to the glass, and actually
    looks like a small, one-inch square shock sensor. The cord plugs into
    a small jack which is screwed into the window sill. Does anyone know
    if these are still made and where can I find them.

    Thanks,
    Bossman

    Those arent bad... shocks for if somene tries breaking them, and pull apart
    for the opening protection .. i still do that sometimes when i do windows
    and people have pets and dont want 1 more thing (gbd) on a wall..

    Actually Robert, I dont think thats what hes refering to.. ive actually
    never used the sentrol 1005 or seen the mon any sort of windows, all i think
    hes refering to is just gold plated pull plugs and a shock sensor.

    Sentrol makes one.

    I'd strongly recommend against using something like this on a window though,
    unless there's some form of glass break detection available as well. It
    would be too easy to defeat (not that the average perp would even know what
    the heck it is)... How did they route the wires to the the sensor?? Can
    you use a recessed mini contact of some kind??

    If they are indeed a combination unit, I'd suggest replaceing them with
    these:

    The Sentrol unit may be a bit bigger than the ones currently in use, but I
    haven't seen the type of shock sensor Bossman's describing for some time (I
    don't even recall who made them)... Memory's not what it used to be... :-(

    till foil was gone.. you should see some of the corners i make.. not the
    best but they work

    Thanks to everyone who responded. After reading the posts, I realize
    now they are just simple shock sensors connected to the home run with
    connectors very similar to the one advertised at AlarmSuperstore.

    Since the shock sensor is fixed to the window glass, it works as a
    pull-apart if the window is lifted. They sure are ugly though, with
    all the wire looped and coiled on the window sills.

    I do sell alot of this aluminum foil. Though it is thicker than old style
    foil, it is easy to handle, and so far I have had no complaints about the
    quality.

    It all depends on its application. I have heard many stories over the years
    concerning foil. Even UL Listed foil is basically useless if installed on
    plate glass. A thief can cut around the foil and walk right in.

    Barrier bars have been used for many years in place of foiling basement
    windows. Even though they are UL listed, they can easily be defeated from
    the outside.

    Most people buy the foil as a deterrent, not as a primary line of defense.

    It doesn't take much of an "opening" for a Lawyer in any given situation...
    There are probably dozens of security devices out there that aren't UL
    listed, yet they're used every day by companies all over North America. If
    you're depending on foil (even the UL listed variety) as your only means of
    detecting an intrusion, you're either stupider than I thought or don't
    install for a living and are clueless...

    I figure it's probably a combination of both of the above...


    Uh-huh... yeah... right... Every worked with aluminum foil?? When??
