A centrally supplied (emergency lighting) system is emergency lighting in which a number of emergency luminaires, exit signs or both are supplied from a common power source (battery bank). Within a building there may be more than one power source, each of which supplies the emergency luminaires and exit signs in a particular section of the building. A single-point (emergency lighting system) system of emergency lighting employs only self-contained type emergency luminaires and the controls necessary for sensing failure of the normal supply and for changing over to the emergency supply, and vice versa. What do I need to do if I replace an emergency or exit light fitting? If you replace a fitting with the same type in the same location and same wattage; you only need to change the fitting. If you replace a fitting with an LED type, this is an alteration and you must comply with clause 1.7 of AS 2293.1 (install test switches). Do I need to be an electrician to replace a battery in an emergency luminaire? Yes, if covers have to be removed exposing live parts, otherwise no. Do I need to be an electrician to replace an emergency luminaire that is connected via a plug and socket? No. Do I need to be an electrician to repair emergency luminaires that are connected via a plug and socket while I am on site? Yes, the repair or mantainace of electrical equipment on site is electrical installation work and requires the issue of a certificate of electrical safety for components above extra low voltage. Is the discharge test facility switch located on the emergency light fitting? No, the discharge test facility switch is remote from the emergency luminaires and simulates the loss of supply to one or more normal lighting circuits for the purposes of testing.
