Glass break alarms- do I need one for each individual window?

This might be a silly question, but wondering the most effective way to leverage glass break sensors. I purchased some battery powered ones, with a red blinking light to install on some of the windows of my new house. A few of my windows are 2 or 3 double pane windows next to eachother, separated by a piece of trim, they also slide up to open half way. Would I need one on each of the 2-3 windows? If I put the sensor on the bottom, would (should) it trigger if the upper pane is broken? I’m really not familiar with them, hoping to get a little expertise to ensure I’m using them properly. Thank you kindly!
