Window Alarms Help Protect Your Home's Most Vulnerable Entry Points!

All windows that are accessible from ground level or windows that could possibly be reached by an intruder on a higher level, should be protected with an alarm sensor.

There are a few different protection devices that are used in the home security industry for protecting your windows.

There are two different type glass break detectors that can be used.

The first glass break detector is a shock sensor that has to be applied to the glass it is protecting with a suction device or a special type tape with an adhesive backing.

The second glass break detector is more popular as one detector can protect several windows within its range.

It is an audio discriminator & it is triggered by the acoustical sound of breaking glass.

This detection device is mainly used as a backup sensor to window alarms that are used to protect individual windows.

For additional information on these two detectors please review the information on my glass break sensors web page

Of the various detection sensors that can be used in protecting your windows, the most popular & widely used window sensors are magnetic switch sensors.

These magnetic sensors are also referred to as window & door sensors. The two different model magnetic sensors you can purchase are, a surface mounted sensor or a recessed model magnetic sensor.

These window alarms are applied to your window using different methods, but they work exactly the same.

A surface mounted magnetic sensor is housed in two small rectangular plastic casings, one holds a magnetically activated switch & the other one holds a magnet.

The magnet section of the sensor is mounted on the wooden or plastic edge of the window & the switch part is attached directly adjacent to the magnet on the window frame.

This magnetic sensor is triggered when someone tries to open the window as the magnet part of the sensor moves up with the window away from the switch causing the magnetic field to be broken. Once the magnetic field is broken the switch creates an open circuit, triggering an alarm condition.

The two window alarms that are used in most homes today are magnetic sensors that protect against anyone opening the window & a glass break sensor that detects the sound of breaking glass.

The glass break detector is mainly used as a backup sensor to the magnetic sensors installed on each window.

Although glass break sensors that detect the sound of breaking glass are fairly reliable, some of these glass break detectors, in a challenging environment, may repeatedly trigger a false alarm.

The detector will sometimes mistake high pitched sounds with the sound of breaking glass & therefore trigger a false alarm.

With these window alarms the first thing you may want to determine is what high pitched sound is causing the false alarms & then try to stop that high pitch sound from happening.

If there is a problem stopping the high pitch sound from happening or to move the sound out of the sensors range, you may want to look at replacing that detector with one that uses dual technology.

Dual technology glass break detectors were designed to stop false alarms that are caused due to challenging environments. For more detailed information on these dual tech sensors you should checkout my dual technology sensors web page.
