In addition, a battery-operated smoke detector with a low battery also emits a single "chirp" sound approximately once
every 20–30 seconds, identifying itself as the smoke detector with the weak battery.
Note: The low battery message comes on as a warning that battery replacement in indicated sensor(s) is due within 30
days. In the meantime, a sensor causing a low battery indication is still fully operational.
Important: Use only batteries recommended by your installer as replacement.
Silencing Low Battery Warning Tones at the Keypad
You can silence the keypad's warning tones by pressing the OFF key, but the keypad's low battery message display will
remain on as a reminder that you have a low battery condition in one or more of your sensors. When you replace the
weak battery with a fresh one, the sensor will 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. If the sensor is not
activated, the display will automatically clear within approximately 1 hour.
Routine Care
Treat the components of your security system as you would any other electrical equipment. Do not slam sensor-
protected doors or windows.
Keep dust from accumulating on the keypad and all protective sensors, particularly on motion sensors and
smoke detectors.
The keypad and sensors should be cleaned carefully with a dry soft cloth. Do not spray water or any other fluid
on the units.
