Maintenance
Conduct KeyPad Combi functionality tests regularly. The optimal frequency of
testing is once a week. Clean the body from dust, cobwebs, and other
contaminants as they emerge. Use a soft dry cloth that is suitable for equipment
care.
Do not use substances that contain alcohol, acetone, gasoline or other active
solvents to clean the detector. Wipe the touch keypad gently: scratches can reduce
the sensitivity of the keypad.
The batteries installed in KeyPad Combi provide up to 3.5 years of autonomous
operation at default settings. If the battery is low, the system sends appropriate
notifications, and LED
X (Malfunction) smoothly lights up and goes out after each
successful password entry.
KeyPad Combi can work up to 2 months after the low battery signal. However, we
recommend you replace the batteries immediately upon notification.
It is advisable to use lithium batteries. They have a large capacity and are less
affected by temperatures.
