Installation
Validating the Field Apparatus
Entity Parameters
The entity parameters of the barrier outputs must be
matched to the entity parameters of the field apparatus
power inputs.
The barrier outputs are defined using the symbols

The field apparatus power inputs are defined using a
combination of the symbols Ui, Ii, Pi, Ci, and Li. It is pos-
sible that all parameters are not defined. In some cases
the equivalent value can be calculated. Refer to the
appropriate installation standards if this is the case.
