Battery Tutorial: Glass Break (GB2) (copy)
You will need two CR123A batteries and a key to change the battery in your glass break detector. Before changing the batteries, make sure that your system is disarmed and note that you may here some beeping from the panel when you open the detector. Go to your glass break detector and use the key to push down the tab on the top of the detector. Pull the detector towards you and off of the base. Remove the old batteries and replace it with the new CR123A batteries. Line up the bottom of the detector and snap back into place. Make sure that it snaps into place with no gaps. Remember to safely dispose of the old batteries. For more information and tutorials, please visit support.vivint.com.
