Everything you need for a compliant zone chart
Purpose-built for fire & security engineers — not a generic drawing tool.
Draw floor plans fast
Trace rooms and doors over an uploaded plan, or sketch from scratch with snapping and grid guides.
Colour-coded zone key
Assign rooms to fire alarm zones. Every zone gets a unique colour and hatch pattern, kept in a shared key.
Fire alarm device symbols
Drop smoke, heat and multi-sensor detectors, manual call points, sounders and VAD beacons anywhere on the plan.
Markers & escape routes
Add 'You Are Here' markers, fire exits, escape route arrows, assembly points and a north compass.
Multi-floor projects
Add as many floors as the building needs. The zone key stays consistent across every level.
Print-ready exports
Produce all floors on one sheet or one page each, and export crisp SVG, PNG and multi-page PDF.
From plan to chart in three steps
A guided workflow that mirrors how the chart actually comes together.
