Description
The York S1-55000-335DCT Duct Detector Head Smoke Photo SL-2000-P is a photoelectric sensing unit used to detect smoke particles in air moving through ductwork for early fire warning and system protection. It is established in air handling systems, ventilation networks, and airflow ducts where rapid fume detection is required to prevent spread through building zones. It operates through a light-scattering detection chamber that identifies smoke presence and sends a signal to the control system for immediate response. Integrated within HVAC systems, it mounts inside duct detector housings to monitor airflow and fire safety features.
