Audible throughout the building
Minimum sound pressure and uniformity of the emergency PA are simulated and checked per room — undersupply becomes visible immediately.
Plan voice-alarm systems to EN 50849 — with SPL simulation from the IFC model
Place loudspeakers automatically from detected rooms, simulate sound pressure as a heatmap, check minimum level and uniformity — including the 100 V power budget. Straight from plan or model.

Standards that carry the planning
VAS in case of fire
Loudspeaker placement and level evidence provide the solid basis for planning voice-alarm systems for fire emergencies.
Basis for the control unit
The 100 V power budget with reserve serves as the sizing basis for amplifiers and the voice-alarm control unit.

Questions about VAS planning
How does PlanWerke calculate the sound pressure level?
For each room the level of all loudspeakers is summed energetically and shown as a heatmap — with minimum, average and maximum per room. Undersupply and overload are visible immediately.
What does the level analysis check against EN 50849?
Minimum sound pressure and uniformity of coverage per room as well as overload warnings per room and alarm zone — as the basis for the level evidence in the planning documentation.
What does the export for tendering contain?
Bill of materials of the loudspeakers as CSV, level analysis per room and the 100 V power budget including reserve — plus BCF comments for team handover.
What does VAS planning cost?
Nothing. Voice-alarm planning is marked as beta: it is still under development and therefore free on every plan — including the free plan. We are focusing entirely on the fire alarm system (BMA) first, and results may change with future versions. Any change will be announced beforehand in the help centre changelog.
