a shared parameter. (See Chapter 6, “Parameters,” for more information on
shared parameters.)
Figure 21.13
shows that a shared parameter has been
added to a device family for its candela rating. There is no label in the device
family for this parameter; it is simply there to give a value when the device
is tagged in a project.

Shared parameter added to a device family for tagging
This type of functionality in your device families allows you to place the text
associated with the device anywhere in the project view to avoid conflict
with other graphics. A tag family must be created that reads the parameter
used. When creating the tag, be sure to categorize it as a tag for the
appropriate typeofdevice. Another benefit ofusingatagforadevicelabelis
that you can use a leader on the tag when necessary.
Figure 21.14
shows how
the device with a custom parameter and a tag can be used in a project. The
text shown is a Fire Alarm Device tag that was created to read the custom
instance parameter called Candelas.
