You will need one CR2032 battery and a coin such as a penny to change the battery in your panic pendant.
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 sensor.
Remove the top cover of the pendant by inserting a dime or penny into the slot located on the bottom of the pendant. Twist the coin to pop the cover off.
Remove the old battery and replace it with the new CR2032 battery, positive side facing up.
Replace the cover and make sure that it snaps shut with no gaps.
Remember to safely dispose of the old battery.
