Protecting Double Hung Windows
Recessed Installation in Top of Upper Window and Bottom of Lower Window
Protecting double hung windows with recessed or surface-mounted Interlogix magnetic contacts with regular or wide gap switches.
Select position of magnet in window frame. Select position of switch in head or sill. Slightly over-drill holes for switch and magnet. Coat switch and magnet with RTV mounting compound. Insert switch and magnet in holes.
Note: Wide gap switches are polarity sensitive. If switch uses bare magnet, observe correct polarity by mounting magnet with red end away from switch.
Attach ohmmeter to leads and check for proper operation.
Connect switch to loop.
If desired, cover Interlogix switch and magnet with wood filler to camouflage and to improve appearance.
Recessed Installation in Sides of Window
This method of protecting double hung windows is recommended only when walls are open and readily accessible for running wires (i.e., during construction or remodeling). A finished wall will make this a very difficult job, requiring extremely awkward “fishing.”
Requires perpendicular mounting of switch and magnet, and may require a wide gap between switch and magnet.
Drill vertical hole in window frame for magnet. Coat magnet with RTV mounting compound and insert in hole.
Pick position for switch. This will be determined by two requirements:
1) Magnet must not be centered under switch. End of switch must be opposite the end of magnet (perpendicular) as shown.
2) If wide gap switch is used, observe correct polarity by mounting magnet with red end away from the switch end with wires.
Drill hole for switch and insert switch.
Attach ohmmeter to leads. Close windows and test for correct operation. Connect switch to loop.
Surface Installation on Upper and Lower Windows
Select appropriate surface mount switch. Mount switch on head, sill, or jamb in desired position.
Mount magnet on window, directly opposite switch when window is closed. If using switch with self-adhesive, clean surface with alcohol before mounting to assure good bond.
Note: If wide gap switch is used, be certain to align labels on switch and magnet so they read in the same direction (switch is polarity sensitive).
Attach ohmmeter to leads and test for correct operation.
Connect switch to alarm loop.
