If you are having a window replacement job done on your home and have a home security or alarm system in place, it's important to keep the alarm system intact. Here are a few things to keep in mind for a smooth installation.
Professional Alarm InstallationMost window manufacturers recommend that clients’ alarm companies re-install the alarms on a replacement window after the project is complete. Only the alarm technicians are licensed and experienced in reconnecting alarms to new windows, so it is highly recommened. After all, you wouldn’t want an alarm technician installing your windows, so why would you want a window installer reconnecting your alarms? Major legal issues can arise with someone who isn’t experienced in installing new alarm systems. For example, if the window company installs the alarms improperly, then they might end up in a lawsuit if there is a break-in. By having an alarm expert install and test the alarm system that goes with your window replacement, the liability remains with them.
Different Window StylesIssues can arise between alarm systems and a change in window style. For example, if you change from a single hung window (where only the lower sash operates up and down) to a double hung window (where both the top and bottom sashes operate), you’d need to modify the alarm system to include extra wire and a tag on the top sash because the original system’s wires only connect to the bottom sash. Or if you change from a double hung to a casement window, which has a totally different mode of operation, you would have to upgrade to a completely different alarm system for that window.
Alarm OptionsFor wired alarms that attach to the windows themselves, the two most common options are flush mount alarms and surface mount alarms. A flush mount alarm is attached to the bottom of the window frame underneath the lower sash to detect when the window is opened. However, some windows have a raised lip in that exact location called a dam system, which prevents a flush mount alarm from being installed there.
Additionally, our window manufacturer does not allow us to drill holes through the frame of the window as is required for installing flush mount alarms, due to the possibility of moisture penetration into the wall. Our solution to that issue is generally just to lead the wires to the inside the window (instead of the outside) and allow the alarm company to connect the windows with a surface mount alarm on the face of the frame itself.
Getting a window replacement can be a great opportunity to install a new, upgraded type of security system that avoids a lot of these wiring issues. Some alternative alarms that protect the home from intruders include the following:
- Glass breakage alarms. With this system, just one sensor in the middle of the room can pick up the sound of breaking glass from any window in the room.
- Motion detector alarms. While the other systems are designed to detect burglars in the process of breaking in, this system ensures that if they do manage to get past the first defenses, their movements will be noticed right away.
- Wireless alarms. These systems are much more sophisticated than first generation models and a great solution for homeowners who want to have the sensors on the windows themselves. When mounted on the checkrail in the middle of the window, they can sense movement from both the top and bottom sashes on double hung windows, preventing the need to install tags on both sashes.
