Sprinkler Spacer
Room dimensions in, head count and spacings out, with every wall and between-head distance checked against the standard.
On site: Know how many heads a room takes before you start setting out.
Spacing & coverageFree for the NZ Fire Protection Industry
The sprinkler maths,
in your pocket.
Head spacing. Obstruction rules. Drawing scale. Sloped pipe cut lengths. Four tools that answer the questions you actually stop and work out on site, on the phone that's already in your pocket.
Built by a fire protection designer who spent years on the tools first.
What's In It
Four tools, one login
Each one does a job you'd otherwise do on a calculator, on the back of a duct offcut, or by ringing the designer.
Obstruction Calculator
One sprinkler against one obstruction, resolved against the published obstruction rules. If it fails, it tells you how far to move the head.
On site: Settle the beam argument on the spot, with the reasoning shown.
Obstruction rulesDrawing Scale
Calibrate off a known dimension, then measure anything on the sheet. It warns you when a drawing is not a standard scale.
On site: Catches the reduced print before you set out to a wrong dimension.
Site measurementSloped Pipe Solver
The plan dimensions the flat run; the pipe runs the hypotenuse. Enter the run and the pitch, get the length to cut.
On site: Stops you cutting to the plan dimension and coming up short.
Site trigonometryWhy It Exists
“I would have paid for this myself when I was on the tools.”

Straight From The Standard
Built on the printed tables, not rules of thumb
The rules come from the same standard your design is assessed against, transcribed and tested, with the working shown on screen.
Spacing & coverage
Maximum head spacings, wall distances and coverage areas for automatic fire sprinkler systems.
Obstruction distances
Sprinkler distances from obstructions, including conventional upright heads.
Sectional check
The obstruction tool draws the section and dimensions it the way the standard does.
Guidance only
Head Start is a check, not a design. Always verify independently and consult a qualified fire protection engineer.
