Summary
Smoke detection thresholds expressed as optical density per metre: very early warning levels for aspirating systems compared with values for point detectors. Based on Hyslop et al. (2010), p. 13-2, Ministry of Business, Innovation and Employment (2025b), p. 27, and Schifiliti et al. (2002), pp. 4-23 and 4-25.
