When you replace the weak battery with a fresh one, the sensorwill send a "good battery" signal to the control as soon as the sensor is activated(opening/closing of door, window, etc.), causing the low battery display to turn off.

Donot slam sensor-protected doors or windows.• Keep dust from accumulating on the keypad and all protective sensors, particularly on motionsensors and smoke detectors.• The keypad and sensors should be cleaned carefully with a dry soft cloth.Do not spray wateror any other fluid on the units.
