Application
Duct smoke detectors are a critical life-safety component in commercial HVAC systems. When smoke enters the ductwork, the detector activates — shutting down the air handler or triggering an alarm panel — to prevent the HVAC system from acting as a conduit for smoke distribution. The York S1-029-22291-000 is the correct OEM-specified replacement for York equipment, ensuring proper fit, function, and code compliance.
