Okay, now we’ve covered two of the most common alarm sensors: the wireless door/window sensor and the wireless motion sensor. It’s time to address “Number Three” in any standard intrusion alarm system: the wireless glass break sensor. As was the case in previous posts, we’ll explain how the glass break sensor works, and why it’s an important component of most home alarm systems.
Building Your System from the Bottom Up
Yes, most residential home alarm systems start with door/window sensors and motion sensors, and that’s been true for some time – just about every system includes both of these devices. But we also find more and more customers selecting glass break sensors to enhance a system, as an effective cost-saving device when protecting a group of windows in one room.
And, unlike motions sensors, glass breaks are active in both the “Stay” and “Away” modes. For more detail on that important topic, here’s a link to my post on How to Arm Your Alarm System. Since homeowners are increasingly arming their systems when home at night, and even during the day, glass breaks could help provide you with more peace of mind around the clock.
The Right Design
Plenty of alarm companies try to fit you into a “one-size-fits-most” solution, instead of customizing your system to your specific needs. The right way to design your system is to consider how your home is laid out, and how you will utilize your protection to fit your lifestyle.
Another thing to bear in mind is that our lives change – and so do our neighborhoods! You may want to add devices to your system to increase your sense of security, or use your system differently – and having a system that is flexible and that grows with you can be a real asset. This is another area where an easily self-installed alarm system offers a definite benefit: allowing you to add any device, at any time, easily and affordably.
How Glass Break Technology Works
So, how does a glassbreak sensor work? It listens for the specific acoustical frequency that is generated by breaking glass. Glass breaks sensors are active any time your system is armed, so once you turn your system on (even in the “Stay” mode!), you need to remember that accidentally dropping a glass could trigger an alarm.
These sensors generally have a range of 20 feet in any direction. That means one sensor can cover lots of windows in a single room, as long as there are no doors or walls blocking the “sight” of the sensor.
Where Do You Use Them?
Clustered window areas like sunrooms and kitchens are a natural spot – and one sensor is great for a room with several windows and a sliding glass door, in case the intruder breaks through the glass door. Other good areas are fixed windows (some of my windows are painted shut!), and vulnerable spots where motion sensors will not be active in the Stay alarm mode.
Wireless glassbreak sensors mount on the wall or ceiling, and don’t have to “point” at the glass they are protecting – they just need a clear “line of sight” to do their thing. Bad guys do break glass, often to reach in, and unlock a window: it’s much more efficient to use a single glass break sensor than place a door/window sensor on every window in a room.
Wireless is the Name of the Game
As I’ve mentioned before, the trend has been toward wireless technology for years. That means no drilling, no running wires, and a faster (and cleaner) installation process. It also means that these sensors are easier to troubleshoot, to adjust, and even to move with you –that is, if you are fortunate enough to have a DIY alarm system. See this previous post for the rundown on why wireless sensor technology is the new norm.
Using the right sensor for each application is where an effective home security system starts – and the best alarm companies are committed to providing you with the protection and peace of mind you deserve: adding one or more wireless glassbreak sensors to your system could be the right call for your home. Now we’re another step closer to designing a complete home security system. There are a few more sensors to cover before we get there, so make sure to join us here for the updates. See you next Monday!
