Good Morning Satish
Well as Graham says we already have requirements in BS 7671 and he has referenced these.
Andy has pointed to the HTM 06 series of documents.
You will also need to look at the HTM-05 series of documents that specifically deal with fire.
The HTMs also point to BS 8519 for safety services and CIBSE guides.
You should put your proposal together and Tech. Sub. it to the hospitals fire engineer for approval to ensure that it meets his/her fire strategy for the building.
I recently did a design for a large hospital using LSOH cables with limited fire propagation for ordinary supplies and fire resistant LSOH cables with limited fire propagation for the safety services. All Tech. Subed. for approval which was approved.
So in essence you propose your design and others approve.
Hope this helps.

Thanks on above clarification. I think we can use notes to 560.1 where Essential Medical system is mentioned under the general requirements to Safety services & this will go along with 560.8.1 as you have well mentioned above.
422.2.1 we can use also where cables are supplying the Safety circuits. Also I shall go by your & Heath suggestion HTM-05 & HTM 06 series of documents.
Regards,
Also I shall go by your & Heath suggestion HTM-05 & HTM 06 series of documents.
Just to mention, that "HTM's" only apply in England - Scotland, Wales and Northern Ireland have their own versions of these documents, so there may be slight changes in practice in each of the nations of the UK (as there is with Building Regulations)
Thank you Graham. I have taken note on that
