Defining the Room:
- Existing Rooms: If the room has already been defined using the “Define Layout” app, simply
click within the room to start placing sprinklers. - New Rooms:
- Rectangular Rooms: Draw a rectangle to define the room’s perimeter.
- Irregular Rooms: Use the “P” key to draw a polyline for irregular room shapes
Defining Beams:
There are some options to define beams.
- Create Line Beam: Draw a straight beam by pressing “L”. Specify the beam’s width and
height. - Create Rectangular Beam: Draw a rectangular beam by pressing “R”, then enter the beam
height. - Select Existing Beam: Choose an existing single-line beam by pressing “B”. Define its width

Additional Tips:
- While dragging the sprinkler, you can press the “Ctrl” button to view obstruction-related
information. - You can also select the “F” keyword to fix the sprinkler position from a specific line.
- If a sprinkler is placed closer than the minimum allowable distance specified by the
standard, a ‘CS’ indicator will appear next to it to warn of potential cold soldering. - To view beam data you can type “BeamSpec” and select the desired beam. The information
will show up in the editor window. - To edit an existing beam, type “EditBeam” and select the beam you wish to edit.
Notes:
The current version of the Sprinkler Layout app is optimized for rooms with rectangular shapes and
