Band I / Band II cct separation

Farmboy
Does the principal of Band I / Band II  cct separation re 528.1 apply within equipment? A DETA mechanical chime with internal transformer has LV and ELV wiring right near each other within the same enclosure (the lid of which is easily removable without tools), which seems to moot the requirement to have them separated as per the reg?

    The great advantage of using a bell transformer is that an illuminated bell push can be used at the front door. Also, if you use a conventional bell it will ring for as long as the bell push is depressed, unlike some wireless chimes that only ring/chime/play for a few seconds. This is ideal for the hard of hearing or if the dogs are barking or a noisy vacuum cleaner is being used in the house. The old Friedland bell transformers were very good and lasted for years. They could be situated by a fuse box or hidden elsewhere. A mains rated cable was run to them and a bell wire run to the bell and bell push. As they were normally fixed onto a wall they never obverheated. The supply terminals and extra low Voltage terminals were situated at opposite ends of the transformer so were kept respectably separated. The tappings were 3, 5 and 8 Volts at 1 Amp., I believe so various types of bells/chimes could be supplied
