Gamewell FCI PSD-7155-RC

The Gamewell FCI PSD-7155 is a conventional photoelectric smoke detector head engineered for early detection of smoldering fires in commercial and industrial fire alarm systems. This single-chamber optical smoke sensor uses light-scattering detection technology to respond to visible smoke particles, making it effective for a wide range of fire types. Compatible with standard Gamewell detector bases, the PSD-7155 offers reliable performance in clean environments where photoelectric technology provides superior sensitivity to slow-burning fires.
