Fire alarm panel supply

Apostolos over 5 years ago

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

The fire alarm panel should be on a dedicated supply, in fire resistant cable and terminated in a double pole fcu needing a special tool. BS5839 overrides BS7671 (in this instance) and the recommendation is that a non RCD circuit should be used since this is a life safety system. Will most definitely be a L1 cat system with a minimum of 24hrs standby capacity.
