MAINTENANCE

With normal use, your system requires a minimum of maintenance. The following points should be

observed:

1 Do not wash the keypad with a wet cloth, and do not use household cleaners, such as glass cleaners,

on the keypad. Light dusting with a cloth slightly dampened with plain water should remove normal

accumulations of dust.

2 For other system devices such as passive infrared, ultrasonic or microwave motion detectors,

glassbreak detectors and so on, consult the manufacturer’s literature for testing, cleaning and

maintenance instructions.

3 It is recommended that the back-up battery be replaced every three years. Contact your installing

company for information on replacing the battery.
