A visual inspection, described in Australian Standard AS 2293.2:2019, is necessary to ensure the compliance and operation of emergency lighting and exit sign systems. These inspections complement automated monitoring by identifying physical faults, non-compliant layouts, and environmental changes that technology is unable to identify, enhancing safety and compliance with the Standard.
The Functional Statement E4F1 of the National Construction Code (NCC) requires emergency lights to activate immediately when normal lighting fails. This article explains the need for circuit sensing, especially when artificial and emergency lights are on separate subcircuits.
On several occasions, I have been asked about the requirement for the installation of emergency lights in small (Class 6) retail buildings. When I say small I mean less than 500m2.
