Good morning all
I have a customer who after having refurbished his house was informed by the council that A cat D LD3 fire alarm system was needed
Its not possible to install this without trashing his house (even with Aico wireless bases)
It has been decided to fit a completely radio fire alarm system with main panel the usual type I have fitted in nursing homes etc when I was an apprentice some years back
Closer to Grade A except no call points.
The fire panel supply is a bit of a problem because the fuseboard only has a spare way on the rcd protected side (dual rcd board)
There is no room for a separate fuse board or henley blocks etc as the board and meter are in a cupboard and fire panel just has room to go below.
Options seem to be
Rcd protected feed (fp) panel will have 72 hour battery backup
Feed direct from load side of main switch
(Obviously frowned upon these days and possibly not accepted anymore)
Or alter board config for one unprotected mcb next to main switch but neutral will have to come direct from load side of main switch as no unprotected neutral bar
What do you think is the better option
