Installation of Everspring SE812-US Z-Wave Indoor Siren:
You can set up the Everspring Z-Wave Indoor Siren (SE812-US) and replace the batteries by following these instructions:
1. Remove the fixing screws of the Indoor Siren, which is located on the bottom edge. Then remove the rear cover by sliding the battery door of the siren.
2. Take four LR14 1.5V size alkaline batteries and insert them into the battery compartment. Make sure that you insert the battery in its correct polarity.
There is another option instead of batteries and that is a power adapter, which is optional.
Find a cable track inside the unit for the power adapter.
Install the power adapter by connecting the plug of the power adapter to the DC jack found inside the unit.
Then route the cable along the cable track.
3. Mark the position on the wall by using the rear cover as a template. You would have to mark three fixing holes. Use the screw to fasten the rear cover to the wall.
