To change the battery in an Infinite Prime wireless alarm sensor, remove the sensor cover by pulling the front of the sensor down, and carefully prizing open the bottom with a screwdriver. Please note, at this point the alarm will set off.

You should see the battery inside the sensor. Simply remove and replace it.

Finally, make sure you replace the lid firmly – so it doesn’t disturb the tamper circuit.
