Congratulations on your new SimpliSafe system! Before installing your sensors, you'll need to install your core devices. Then, follow along with the video below to install your Glassbreak Sensors to your brand new system.
NOTE: You can adjust the sensitivity of the Glassbreak via the switch on the back of the sensor. Simply slide the Glassbreak Sensor off its bracket, and you will expose a small black switch. Slide it towards the "L" to lower the sensitivity.
