Single Zone Panels
A single-zone panel controls all vents and dampers as one group. When activated, all outputs operate simultaneously. Single-zone panels are suitable for simple stairwell or corridor systems in smaller buildings where all vents should open on any activation.
Multi-Zone Panels
A multi-zone panel allows independent control of different areas of the building. For example, in a residential block, the panel might have separate zones for the roof vent, each floor's lobby vent, and the smoke shaft dampers. Multi-zone panels are required wherever the fire strategy calls for selective activation.
Which Do You Need?
The choice between single and multi-zone is determined by the fire strategy, not by preference. Buildings with more than one smoke control zone — which includes most buildings with a smoke shaft — require a multi-zone panel. The fire strategy document prepared by the fire engineer will specify the zoning requirements.
Cost Considerations
Multi-zone panels carry a higher capital cost than single-zone equivalents, but the difference is often modest relative to the overall system cost. Specifying a single-zone panel where a multi-zone panel is required is a compliance failure that will be identified at commissioning.
