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
Parents

    OK - an hotel is most certainly not domestic - for starters you will almost certainly be providing a BS 5839 Part 1 fire alarm system (probably to L1 Category)


    If you read the regulation group again, look for the differences between a domestic property where there is no duty holder and an hotel  - where there will most certainly be a duty holder


    From there, determine if the presence of a duty holder suggests to you that the installation is under the control of skilled or instructed persons


    Also, ascertain if your cable which has a foil sheath which is in homogenous contact with the CPC is of a type where it has an effective earthed metallic covering capable of withstanding the earth fault current at that point in the installation based on the prevailing fault level and selected protective device
