Battery Tutorial: Motion Detector (PIR2) (copy)
Motion Detector (PIR2) You will need two CR123A batteries for your motion detector. Before changing the battery, make sure that your system is disarmed and note that you may here some beeping from the panel when you open the motion detector. To open the sensor, grip it with your thumbs on the front and your fingers wrapped around the back. Push upward with your thumbs to slide the detector off of its back plate. Use the black tab to remove the old batteries and replace with the new CR123A batteries. Slide the sensor back onto its back plate and make sure it snaps into place with no gaps. Remember to safely dispose of the old battery. For more information and tutorials, please visit support.vivint.com.
