Window sensors operate according to the same principles as door sensors. A trigger is connected to the window itself, with a switch attached next to it on the window frame. When the window is opened, the trigger is removed from the switch--which either breaks an electrical circuit or completes one, depending upon the system--and the alarm goes off. More elaborate security sensors can be embedded in the glass by professionals--which activates the alarm when burglars break the glass--but most household window alarms can be easily installed by the homeowner himself.
Step 1
Select a point on the window to install the sensors. Ideally, this should be a point about 6 or 7 inches up. It should be high enough to crack the window on warm nights, but not high enough to let anyone crawl in through the opening. With windows that open inward or outward, place the sensors on the top or bottom of the frame close to the side with the window's hinges. It should allow you to safely crack them just as you would with other types of windows.
Step 2
Screw the trigger into place at your selected point on the window. The trigger should allow you to place it flush against the window, so you can still open and close it normally. (Be sure to use flat-head screws).
Step 3
Attach the switch to the window frame so that it lines up exactly with the trigger. Secure it in place with screws or drywall nails and make sure that it is flush against the frame like the trigger.
Step 4
For window sensors connected to a central circuit board, you will need to run wiring from the switch to the control panel. Ideally, your house will be wired internally through the walls. If not, you can simply run wires down the window frame and along the bottom of the wall until you reach the circuit board. Strip the insulation off the ends of the wires and screw them into place on the matching terminals of the switch (the terminals should be labeled to let you know which wire to attach where). Then connect the other end of the wires to their appropriate housings on the control board. Make sure there is no electricity running to the control board when you do so.
Step 5
For wireless window sensors, fit a battery into the appropriate place on the switch and make sure that it is held securely. The exact type of battery may vary depending upon the specific sensor, but it is usually a common household battery such as a "C" cell or a 9V. Sensors with specialized batteries should have one included in their kit.
Step 6
Turn on the alarm system and then open and close the window. The alarm should go off as normal.
Skill: Moderately Easy
Ingredients:
- 2-part alarm sensor
- Wiring
- Screwdriver
- Screws or drywall nails
- Battery
Tip: Always instruct your family members on the proper use of the alarm, and let them know which windows are set up with sensors. Let them practice turning the alarm on and off at least once, and make sure they understand what to do when they hear it.
Warning: Beware of inadvertently triggering false alarms. Not only do they reduce your own readiness, but police and emergency services will sometimes be instructed to ignore alarms coming from an address known for accidental triggers.
