AI Drafting for Fire Protection

Sprinkler and fire alarm layouts are rule-bound and repetitive, and they are the first sheets to break when the ceiling plan or the ductwork changes. Nomic drafts sprinkler, standpipe, and fire alarm device plans in CAD from your hazard criteria and the reflected ceiling plans, checks them against the NFPA editions you name, and leaves hydraulic design and sign-off with your designer of record.

On the sheet

Fire Sprinkler Plan, annotated

A fire sprinkler plan with the main, branch lines, and heads spaced to the hazard classification.

  1. 1Sprinkler head at listed spacing
  2. 2Branch line feeding the heads
  3. 3Cross main in the corridor
  4. 4Riser to the floor control valve

The problem

Head layouts get redrawn every time the ceiling moves

A sprinkler layout depends on the reflected ceiling plan, the hazard classification of each room, the ductwork, the light fixtures, and the beams. When the architect shifts the ceiling grid 6 in. or the mechanical contractor runs a 54 in. duct through a corridor, heads have to move, spacing has to be rechecked, and obstructed areas need heads added below. The layout technician redraws branch lines that were already right a week ago.

Fire alarm plans have the same churn: strobes get moved when a room is split, a duct detector is missing because the air handler grew past 2,000 CFM, and a pull station ends up more than 5 ft from the stair door after a door swing changes. Each fix is small, and each one is a plan review comment if it gets missed.

01 / Layout

Sprinkler and standpipe layouts from the ceiling plan

Attach the reflected ceiling plans, the mechanical plans, and your hazard criteria. Nomic places heads within the spacing and coverage limits for each hazard, centers them in ceiling tiles where your standard calls for it, draws branch lines and mains on your layers, and locates standpipe hose valves in each exit stair.

  • Heads placed by hazard classification, room by room
  • Branch lines and mains routed around ducts and beams
  • Standpipe risers, hose valves, and the fire department connection located
02 / Check

Spacing and obstructions checked against NFPA 13

Nomic checks its own layout against the NFPA 13 edition you name: spacing, coverage per head, distance from walls, and obstructions from ducts and beams on the mechanical and structural sheets. The hydraulic calculation and the design sign-off stay with your designer of record or NICET-certified technician.

  • Coverage area and spacing checked for each hazard
  • Obstructions wider than 4 ft flagged for heads below
  • Remote areas marked for the hydraulic calculation
03 / Fire alarm

Fire alarm device plans that follow the room layout

Nomic places initiating devices and notification appliances from your engineer's design criteria and the architectural plans, then counts them for the riser and the battery and voltage drop work your engineer does. Devices that depend on other trades, like duct detectors and elevator recall detectors, are tied to the sheets that require them.

  • Pull stations, smoke and heat detectors, horns, and strobes placed
  • Duct detectors located from the mechanical equipment schedule
  • Device counts per floor in Excel and on the fire alarm riser

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • NFPA 13 sprinkler installation
  • NFPA 14 standpipe systems
  • NFPA 72 fire alarm and signaling
  • IBC Chapter 9 and the International Fire Code
  • Local fire marshal amendments
  • Reflected ceiling, mechanical, and structural sheets

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Yes. Nomic works in CAD on its own computer and saves DWG sprinkler plans with heads, branch lines, and mains drawn on your layers. It places heads within the NFPA 13 spacing and coverage limits for the hazard your designer assigns to each room.

No. The hydraulic calculation and the design sign-off stay with your designer of record or NICET-certified technician, as your jurisdiction requires. Nomic drafts the layout, marks the remote areas your designer identifies, and checks spacing and obstructions so the designer starts from a cleaner sheet.

Yes. Nomic places pull stations, detectors, and notification appliances from your engineer's criteria and the architectural plans, checks them against the NFPA 72 edition you name, and keeps device counts for the riser diagram.

No. Nomic is not a plugin. It saves DWG files you open in AutoCAD or any DWG editor, plus a change list your team can apply in whatever software runs the hydraulic model.

When a new reflected ceiling plan or mechanical background comes in, Nomic compares it to the last one, moves the affected heads and branch lines, rechecks spacing and obstructions, and clouds every change for review.
