MAINTAINING YOUR SYSTEM
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.
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 touchpad and all protective sensors, particularly on
motion sensors and smoke detectors.
The touchpad and sensors should be cleaned carefully with a dry soft cloth. Do not spray
•
water or any other fluid on the units.
