Emergency Lighting and Exit Signs for Buildings update. System design, installation and operation this Standard The objective 22993.1 this Standard is to provide designers, installers and certifiers of emergency lighting and exit signage schemes with the relevant requirements and guidance for the provision of emergency lighting and exit signs to all designated spaces within a building.
Provisions and requirements for centrally supplied systems have been simplified and upgraded. Two sets of tables are contained within Appendix E and F. Further to these items, some other definitions have been revised to support these new definitions or to clarify previous ambiguities.
The use of spacing tables for stairwells has been revised and simplified. Within buildings required to be constructed of fire-resisting elements, there are no longer separate provisions for buildings supplied with automatic sprinkler systems compared to buildings without.
The calculations for the classification currently do not assess the contribution of luminance beyond this degree geometric limit.
This is to ensure an acceptable level of illumination for the safe 22931. of occupants from those spaces in an emergency situation. Click here WA Member login.
Many of the section headings have been re-worded to reflect their application better and the sections re-ordered to assist in the reading of the document. The clause specifying the illumination requirements has been moved to Clause 4.
Made possible by our Business Partners: System design, installation and operation. This standard came into effect on 29 Juneand is applicable from this date.
Spacing tables have been moved to a normative appendix. Some clauses have been moved to assist reading and application of the Standard.
Inspection and maintenance Appendix E contains tables based on 0. Rather than modifying spacings using a set of rules, to achieve the higher illumination levels required in stairs, and spacing tables based around 0.
However, definitions for these types of lighting are included in this edition of the Standard. To assist in the application of this Standard, definitions are included for the following: The class of cable protection has been standardised to be WS4X protection, and the fuse type within terminal boxes has been widened to include fuses of a higher grade than type gG making it easier the match the fuse with a ceramic fuse holder, as required in the Standard.
Further, with changing technology, unlike fluorescent and incandescent types typical of the available light sources at the time of publication of previous editions of this standard, some luminaries including modern LEDs do not produce light beyond their assessed geometric imitation and therefore may not achieve at the current minimum at all points on the floor.

This Standard distinguishes between documents cited as normative references and those referenced for information only. This series of Standards do not cover items iii and iv.
The principal reason for this edition of the Standard is to specify updated installation requirements and adapt the Standard to current technologies, terminologies and delete out of date references or methods.
