Within a designated area the failure of the normal supply to final subcircuits supplying lighting to that area shall cause each emergency luminaire and exit sign in the area served by the subcircuit to be automatically connected to its emergency power source.
NOTE: This requirement does not preclude other emergency luminaires and exit signs, connected to subcircuits that might not have lost supply, from also being automatically connected to their emergency power sources in response.
Where any part of a designated area is served by more than one normal lighting subcircuit,the arrangement and connection of the emergency luminaires and exit signs shall be such that the illuminance provided by the normal lighting luminaires on the circuits that are sensed for loss of supply is not inferior to that provided by the required emergency lighting.
Where the light source(s) is located more than 2 m from the control gear, cable parameters shall be determined that ensure correct operation of the luminaire to this Standard. If the interconnecting cable traverses more than one fire compartment of a building, or if the cable is longer than 10 m, the cable shall be provided with Class WS4X protection in accordance with AS/NZS 3013.
If a label is used it shall be permanently fixed and indelible. The label shall be adjacent or attached to the luminaire and provide unique identification to aid in locating the emergency luminaire or exit sign during inspection and maintenance. The label shall be readily visible and lettering height shall be a minimum of 3 mm and in a contrasting colour.
NOTE: Consideration should be given to the use of a logical identifier to aid in determining a sequence or pattern when inspecting emergency luminaires or exit signs.
Where an emergency luminaire or exit sign does not bear the identification symbol specified in Figure 2.1, the symbol shall be applied immediately adjacent to it but shall not be located on removable ceiling tiles.AS NZS 2293.1 pdf free download.
