Multi-zone Smoke Ventilation Systems

Multi-zone smoke ventilation projects require careful planning and technical knowledge. We review your drawings, fire strategy and project requirements, to recommend a compliant solution, while helping identify any missing information or potential issues along the way.

You’ll have a dedicated smoke ventilation specialist throughout your project, providing technical advice, spec a compliant system and supporting your project from enquiry through to supply.

Our support doesn’t stop at delivery. We’re on hand during installation to answer technical questions and provide ongoing support,

Multi-zone smoke ventilation systems are designed to control how smoke moves through a building, rather than opening all vents at once.

When smoke is detected, the system identifies the affected zone and activates AOVs in that area only. This allows smoke and heat to be removed from the source of the fire, reducing the risk of it spreading to other parts of the building.

At the same time, other zones can be held closed (locked out), preventing ventilation from drawing smoke into adjacent areas or across different floors.

Every multi-zone smoke ventilation system is designed around the building and fire strategy, so the components required will vary from project to project.

A typical system may include:

• Smoke control panel
• AOV windows, smoke vent louvres and Roof AOVs
• Smoke control dampers
• Smoke detectors
• Manual override controls
• Power supplies and battery backup

Systems can be designed using either natural or mechanical smoke ventilation. Higher-rise buildings (typically over 30 metres) will require a mechanical system.
