Hi all,
On a seven floor building the design suggests to install cable trays containing secondary power supplies to life safety systems inside the smoke extract shaft (life safety panel is on the basement level). I understand that inside the shaft only equipment relevant to its purpose should be installed but not confident if cables should be rising in there. I personally feel uncomfortable for these supplies to be installed in a shaft that is dedicated to extract smoke as if there is any fire incident that is a place that temperature will rise for sure. It should be noted that the cables are FP600S.
So basically there are two questions:
a/ Is it ok to install the secondary supply for the smoke extract fan along the shaft?
b/ same but for secondary supplies to other life safety equipment.
It would be appreciated if you could share your thoughts.
