This method has its drawbacks; the process would need to be repeated for

However, if your project is the right size and shape, this method is a way to
have your diagram tied directly to the model.
Fire Alarm Diagram Using Drafting Tools and Symbols
A more traditional approach is to generate a diagram by using drafting
tools and symbols. This can be done while still utilizing some of the model
information, such as levels and an elevation of the fire alarm control panel
or equipment. You can create a detail section of your control panel and then
add symbols and detail lines to generate the riser diagram. In this section
view, you can show the building levels and use constraints to maintain the
relationship of your symbols to the levels so that, if changes are made, your
diagram updates appropriately. The same symbol families that are nested
into your fire alarm device families can be loaded into your project file for
use in your diagram.
By utilizing the drafting tools available along with annotations and families,
you can generate a fire alarm riser diagram without having to link in a CAD
