The notable feature of VESDA (Very Early Smoke Detection Apparatus) detection systems is their suitability for large areas. VESDA systems are specifically designed to provide early warning smoke detection over expansive spaces where traditional detectors may be insufficient. They use a complex network of pipes to actively sample the air from different points, allowing for the detection of smoke particles at very low concentrations. This proactive approach enables them to identify potential fire risks long before a fire becomes dangerous, making them particularly effective in large data centres and industrial environments.

In contrast, the other options do not align with the characteristics of VESDA systems. While installation costs can vary, they are generally regarded as a more advanced solution and may not be considered cheap. VESDA systems are also automated and sophisticated, reducing the need for manual operation. Lastly, these systems are specifically engineered for smoke detection, ensuring that they are quite capable of identifying smoke, contrary to any suggestion that they cannot.
