Richard, According to the scope of these specifications the following applies, The standards do not apply to Consumer apparatus Apparatus specifically designed for security systems Apparatus designed to intentionally radiate electromagnetic energy Additionally, Section 4 (Definitions) states that professional apparatus is for use in trades, professions or industries and which is not intended for sale to the general public. This section also goes on to define professional digital apparatus and professional entertainment lighting control apparatus. The electromagnetic environment is also defined and it's up to yourself to decide which on the 5 environments detailed that you use. They are, E1 Residential E2 Commercial in light industrial (includes theatres) E3 Urban outdoors E4 Controlled EMC environment (broadcast/recording studios) and the rural outdoors environment E5 Heavy Industrial (EN 50081-2 and 50082-2) If the audio paging and intercom is on a wire only basis (i.e. no RF transmissions etc) then I would take a guess at the generic specifications (50081-1, 50082-1). If you would like more information please contact me. (I have used the 2 specs several times now with no major hiccups materialising) Kind regards Paul Smith ........................................................................ ........
