Overview
Tyco® Illusion sprinklers offer fast response while remaining visually discreet until activation. These decorative, solder‑type, extra‑large orifice concealed pendent sprinklers deliver quick response and standard coverage for architecturally sensitive environments such as casinos, hotel lobbies, office buildings, churches and restaurants. The flat cover plate preserves interior décor and the design is suitable where water pressure is limited but a higher applied water density is required.
