About Site Trees
Overview
A site tree allows you to create labels for specific, physical areas of a building and assign fire
alarm points to these labels. When complete, a site tree graphically depicts the layout of the
site and gives an indication of every point’s location within the site.
A site tree reads from left to right, with general divisions of the site (such as Building A or
West Wing) listed on the left side and specific areas of the site (such as R&D lab or Boiler)
listed on the right side. Points are listed on the far right of the tree and are the smallest unit that
can be added to a site tree.
Figure 9-1 shows a typical site tree.

Terms and Concepts
Important terms and concepts related to a site tree include:
•
Book icons represents element of the tree that contain subordinate elements. In Figure
9-1, for example, the 1ST FLOOR book indicates that some number of building
components (either points or smaller divisions of the building) are contained within it. A
plus (+) sign to the left of a closed book indicates that the contents of the element are not
currently displayed. Conversely, a minus (-) sign to the left of an open book indicates that
the contents of the element are currently displayed.
•
A page icon represents an element of the tree that contains no subordinate elements.

Points, which are the smallest division of a site tree, are always represented by a page.
