Placement of Glassbreak sensor

@rln The first thought I had when I saw your picture was "wow, look at those curtains!".  That could be an issue but to test it, I would put one glass break in the center of the two windows on the opposite wall, put your system in test mode, push the test button on the top of the sensor, and slap your hands near the windows. With base voice prompts on, you should her "glass break sensor". If not, try moving to sensivity switch in the sensor to high and try again.

if that works, and you want to be absolutley sure, call monitoroing center and ask them to put your entire system in test for x time. (I am always very conservative and tell them 2 hours).  Arm system, keep curtains closed, open window and go outside with a pot and break a glass. (I tested on a neighbors old windows he replaced, a hammer and drop cloth.  Yeah, a bit extreme but 100% my glass sensors work.)

Finally, call SS and ask for installation location recommendiatons. All else fails, use two sensors.  Please post your outcome here if you get a chance.

Hi @rln,

It's recommended that Glassbreak Sensors are installed facing the window you want to protect. With the area you're pointing to in your image, you might run into a case where it's facing only one window.

Captain makes a good point by calling out your curtains. For windows with heavy curtains, we recommend placing your Glassbreak Sensor 5-10 feet away from the window. Depending on how wide your room is, if there's a wall opposite the windows that could be a good place to mount the sensor. Or, if you have a table or shelf (or really any flat surface) about 5-10 feet away, you could face it toward your windows and place it there, too.
