THE SPRINKLER SYSTEM: SYSTEM CONFIGURATION & LOCATIONS FOR CROSS MAINS: A Grid system will be used for the largest area (East of Column G) Primary Main Location: Secondary Main Location:

3” to the left of the 2nd bar-joist left of Col A. 3” to the left of the 2nd bar-joist right of Col G.

A Tree system will be used for the smaller area (West of Column G) Cross Main Location:

3” to the right of the 1st bar-joist right of Col H (will be connected to secondary main of grid system)

Elevation for all Mains is 13’-0”

LOCATE THE SPRINKLER RISER (Water Supply): 1. SETTINGS \DEFAULT PROPERTIES \SUPPLY, On the ‘General’ tab, create a new

default layer called “Supply” and click OK. Create New Layer

2.

Zoom In (Middle Button Mouse Gesture) to the upper-right corner of building (the Riser Room is in this corner – WALLS layer must be ON):

Page 1

Next, we’ll use a “snap offset” to place the supply in the drawing a specific distance from a snap point. The key is to hover over a snap point without clicking on it, and typing in the distance to offset on each axis, then pressing [ENTER]. 3. TOOLS \SUPPLY, Position the cursor over the upper right inside face of

wall intersection, don’t click – just hover.

4. Type the desired offset from the

snap point: s-5,-1,6”, then press [ENTER]. Right-click to end the supply command.

The supply will be inserted at a point 5 feet west of (negative X), 1 foot south of (negative Y), and 6” higher (positive Z) than the intersection snap point. The point you’re referencing is at zero elevation.

5. Double-Click the supply

element to view its properties. Leave the default values and click OK.

6. Lock the Supply Layer

Check the ‘Status Line’. Click on the supply and note that the Supply elevation is 0’-6 above Finish Floor. Zoom All

Elevate Sprinkler System Components to Roof Planes: 37. Select any 1 sprinkler, press & hold the [CTRL] key, Right-Click on any

piece of pipe and choose ‘SELECT ALL LIKE SELECTED’ to select all of the current sprinkler system components. 38. ROOF PLANES \ELEVATE ELEMENTS TO ROOF PLANES, Apply a 1’-0” offset

‘below the roof plane’.

This must always be a positive number; otherwise the command will have the opposite effect! Also note that an object must be below a plane in order to be elevated to it. If you need to elevate an object that is above a plane, simply lower the object(s) then elevate with this tool.

If Sprigs were desired, the heads would be elevated first, then the pipes with a different offset. The uprights would then be connected with the ‘Connect Sprinklers To Pipes’ tool described in the next Module.

3D Tip: To elevate or lower an object, select it and type: ,,-10 for example (no need to type the zeros), then press [ENTER]. This will lower the object 10 feet in the negative Z direction.

Click the ‘Cleanup Intersections’ button. Click again. Notice that the pipe has automatically changed to: Feed Main

Owing to the internal intelligence built into all system components, one of the many unique features of the ‘SIMPLE INTERFACE’ is that the program dynamically generates all system piping designations internally by recognizing the size, configuration and orientation of the pipes. Had another piece of feed main been drawn, continuing from the 1st piece, both pipes would have automatically been recognized as “Feed Main” type pipe. With a simple click on the ‘Cleanup Intersections’ button – any revision to the system piping, no matter how extensive, automatically updates all selected system pipe types to ensure complete system integrity.
