system will send an appropriate noti cation to the Ajax apps, and the LED will
light up and go out gradually when the detector raises an alarm.
We recommend you replace the batteries immediately upon noti cation. It is
advisable to use lithium batteries. They have a large capacity and are less
affected by temperatures.
