II.13. FILTER & PROTECTION UNIT – FPBASE, FPEXP
The external lines that are connected to the system and the extension lines coming
from other buildings are open to environmental effects like lightning or AM radio
interference.
In order to protect the system against lightning and radio interference, KAREL has
external modules that can be connected to both extensions and lines. These
modules are presented in two different models:
a) FPBASE Filter & Protection Base Unit,
b) FPEXP Filter & Protection Expansion Unit.
Both units are capable of handling four lines. The difference between FPBASE and
FPEXP is the base cover, which exists only on FPBASE unit. FPEXP units are
installed on top of an FPBASE unit. So, if a Filter and Protection Unit is required for
a system then an FPBASE unit must be used and depending on the capacity of the
ports that must be filtered and protected, FPEXP units can be added.
The outlook and structure of FPBASE and FPEXP units are illustrated in the
following figure.
