I've been given the task of moving a small datacenter (3 Racks) into a new building where a server room was built with water sprinklers. The issue was raised and the contractor changed it to an FM200 system. I'm not sure who hired these guys or what the outcome will be b/c they have turned to me to find out how to seal the cable routes going into the ceiling (seems like they should know this?).
Essentially we have a cable ladder going from the racks to the wall and all the cables are bundled into 2 x 3 or 4 inch bundles passing through a ceiling tile.
The contractors idea was to form a 'collar' to wrap around each bundle with pvc piping and fill it with foam... I've seen this with indoor/outdoor conduits, such as those that might lead back to a demark.
Is this a good idea? It seems like any movement on the cables would cause gaps in the foam... or the foam might affect the cables' insulation... and it seems like itll be a huge pain to run cables in the future...
What is the right solution? Thanks in advance!
