Fire alarm panel supply

Apostolos
Good morning.

I have a question that may sound silly so excuse my ignorance in advance

I have a Fire Alarm Panel

This is going to be fed through FP200.

However the installation of the FP200 would need an RCD because it is chased within a stud wall less than 50mm from the surface.

Can I omit the RCD on the grounds that it is a critical system for the safety of people?

Is there anything like that in BS7671?

It seems really counter intuitive to use an RCD on a Fire Alarm Panel...

Thanks

    An ariticle about fire alarm cables for use in thin walls or partitions - www.voltimum.co.uk/.../fire-alarm-cables-use-thin-walls-or-partitions-0 - needs you to sign away your soul to read it, Basically because it meets the nail penetration test  BS8436 cable can be installed without additional protection if buried in a wall<50mm etc but olnlly on a low current  type b breaker/RCBO  - or the foil may blow out first.

    www.napitonline.com/.../CP 3 08 P 11-12 BS 8436 Cables.pdf here  also suggests BS8436 cable as a get out of RCD option.


    Or you could  use a length of thin SWA for the vertical drop, and have a joint at ceiling.
