FSD's = Fire Smoke Dampers ? ? ?
This really needs to be determeined between the HVAC/mechanical contractor and your company.
It's one of those situations where some understanding needs to be gained by having to deal with another contractor.
A lot of times its designed as required but no thought is given to it as to who's going to apply the work.
Some examples could be that the mech. needs just 4 circuits, they need a circuit at a certain point of use(to be determined), and your company is not responsible to hook it up! They need circuits to all points and you do need to hook them up!
They only need four circuits to a control or multiply control boxes and all the fire dampers are controled with low voltage, you might or might not need to run a conduit to point of use. Or your conduit will only be used by the mechanical low voltage technician.
If the HVAC is a large system they might have various zones requiring split up the circuits.
Just about any combinatios of how to get this done might apply, it just depends on the contractor and who's going to get out in front of this to identify the problem, and who's going to pay to get this resolved and the responsbility assigned.
Maybe an RFI is the way to go?
