[!quote] Art Baldwin 2026-02-04 (pp.) Fire, smoke, and combination fire/smoke dampers may require 120V power, and thus electrical takeoff, or only 24V, in which case mechanical will own the scope. Assuming 120V is a budget-conservative estimating convenience, which is generally considered acceptable in lieu of determining specified requirements, but further investigation may be expected if more than a few per floor are shown.
