Four-story office building wants to shut down five large air handlers nightly. Purpose is to lower energy costs when building is unoccupied. This will cause all fire/smoke dampers (FSDs) to close (the smoke detectors in return ducts need minimum operational air velocity).
The FSDs are mostly original from 1985-1988. Only UL tested for 5000 cycles and no dynamic.
I cannot find a code reference to prohibit this and believe that the FSDs are already near the end of their functional lifespan. Many have been replaced due to bad actuators, binding jack shafts and missing blades.
Anyone know of a code reference to prohibit this use or when a FSD must be replaced?
Thanks in advance.
