An easy way to allow some windows and doors to remain open without having to disable the sensor in the panel.

Disabling sensor(s) in the panel when you want to leave windows and doors open has two disadvantages:

1) It's a pain in the neck, and

2) Then there's no security whatsoever at that location.

For some windows and doors, there's an easier and still-secure way to solve the problem. On our casement windows, I simply cemented another magnet in a position so as to close the sensor when the window is opened to the "open-but-monitored" position. Needless to say, the window is opened far enough to let in a breeze, but not far enough to let in a burglar. Our windows have flimsy plastic stops to define this position, so it's pretty easy to find the right spot, but lacking this, you could mark the windows in some way to define the spot. This also allows the lower sash to be opened upward, or the upper sash to be opened downward, or both -- the only criterion is that the sensor must align with the magnet to make the sensor report that the window is closed. If the burglar moves either sash at all, the alarm trips.

Doors are obviously trickier. I haven't figured out a secure way to do the same trick with a conventional door-like door, but for sliding patio doors, just think of them as horizontal casement windows and the same method works. We can leave the patio door open just enough to let the cat in and out, but not enough to allow a burglar to do the same.

True, a burglar might be tempted by the open door or window, but if they're in an instant-alarm group, he or she will be immediately scared off, and if your home is really attractive, you might avoid a broken window anyway.

  • This would work well for my windows, but not sure where you get the extra magnet for your windows?  Is it possible to order just one extra magnet without an entire sensor?

  • I bought a bunch of neodymium bar magnets from apexmagnets(dot)com. I use 1/4" x 1/4" x 1" bars and stick them on the window with either double-sided tape or silicone caulk. They're a little pricey ( 6 for $12.99 plus postage), but really powerful -- the extras make the best refrigerator magneets in the world. They have other shapes as well, but the bars were easiest to work with.

  • Jeri,

    For the Simon XT system, Brinks does not sell individual additional magnets. We have a 10pack of magnets available for the sensors on this system, the part number is 60-729. They would be installed like any other sensor or magnet using double sided tape. We sell a 10pack of 1'' squares of double sided tape as well, the part number for it is 3M-4026.

  • Kelly, can you give us a link to the magnets? Searching on the site for "70-729" results in ho hits.

  • I ordered the magnets from apex and they came very promptly.  Haven't tried them yet. 

    I think I would also put a prop under the window (double-hung) or some other way to secure the window as a reminder when I get up in the middle of the night and want to close the window (which would set off the alarm - who wants that at 2 am?)

  • Michael,

    Per your request here is a link to the 10pack of magnets for the SimonXT, the part number is 60-729 and you should be able to find them on our website.

  • Kelly, thanks for the link. FWIW, I've found the Search facility often fails when looking up products, but once I've found them Brinks generally turns out to offer good deals.

    Jeri, you've found the problem with this approach -- movement in either direction will trigger the alarm. Another possible issue might arise if a burglar fiddles with the door or window and changes her mind. If the alarm triggers a police response, and they see no evidence of an attempted forced entry, you might be charged for a false alarm. A small sliding bolt lock might solve both problems, but wouldn't be real attractive.
