The LIBRA-DXK4RF-433 is a “
smart
”, interactive, menu-
driven keypad designed for your Napco control panel. It
has a digital display to show the status of your system.
This booklet contains important information about the
operation of your system with your keypad. Read it
carefully and keep it handy for future reference. Check the
Glossary for an explanation of terms that may be
unfamiliar to you.
You'll probably find subjects mentioned in this booklet that
do not apply to your system. Napco control panels have
such a wide variety of features that few security systems, if
any, will ever need them all. Your alarm professional has
chosen appropriate features for your particular needs.
Regardless of how your system has been configured, rest
assured that it has been carefully designed and
engineered to the highest industry standards. To assure
optimum safety and security, familiarize yourself with this
equipment. Periodically check its condition and state of
readiness by testing it at least once a week in both the AC/
battery and battery-only modes (ask your alarm
professional how to make these tests).
