Window sensors are essential gadgets for comprehensive home security systems. They can immediately notify you in case someone attempts to access your home from a window. This device works through a switch and a magnet attached to a window frame and a pane. Till the time your window stays closed, the magnet keeps the switch’s circuit intact. However, when the window is opened, the magnet is pulled away from the switch, and the open circuit sends a signal to the control panel and the alarms begin to ring.
The technology behind window sensors is relatively easy, but their importance is crucial. Let's discuss more these essential gadgets which will help you in keeping your home secure.
How does a window sensor work?
You will get wired and wireless window sensors in the market. Majority homeowners choose the wireless version to avoid of the mess of cords.
Reed switches are usually used in routine household items. A window sensor works in a similar manner. It works through a reed switch with a small circuit which sits inside the frame of the window, and a magnet which is attached to the pane, right next to the switch. While the window is closed, the magnet holds the switch’s metal together and an electric current flows in a continuous loop.
However, when the window opens and these two pieces separates from one another, the electrical current stop flowing and the circuit is deactivated. Thereafter, the sensor signals the security control panel and triggers an alarm.
How to install a window sensor?
Like door sensors, window sensors take only a few minutes to get installed. You can use an effective adhesive to attach the sensor to the window. To fix it, place the main sensor on the window frame and attach its smaller piece to the window pane.
While the window remains closed, these two pieces need to be parallel with only a small gap in between. If they are not placed evenly, then they will not maintain a circuit. But when your window is pulled open, the two pieces automatically separate from each other, and the sensor sends alarming alerts the control panel. For more comprehensive protection, you need to have a sensor placed on each and every window in your home.
With some systems, you can also customize how and when the window sensors release the alarm. You may also want to receive the alert only when the window opens with arms or with force. Or, you may even get to hear a notification bell every time a window opens, regardless of whether the central alarm is on or not.
Like any other device, window sensors need some regular maintenance. If you do not use a strong and efficient adhesive, then you may have to reapply the sensor when falls off. Eventually, the sensor can also run out of batteries. In case your window sensor sets off a false alarm or malfunctions, then you can notify your home security company to replace or repair it.
