Description
The York S1-STN-2.5 is a 2.5-foot sampling tube engineered specifically for use with the SL-2000 series duct smoke detectors. Designed to enable early detection of smoke and products of combustion carried by moving air within HVAC ductwork, this sampling tube is a critical component in protecting building occupants and HVAC equipment from fire-related hazards.
Overview
This sampling tube is sized to fit duct widths ranging from 12 inches to 3 feet, making it a versatile solution for a broad range of residential, commercial, and light industrial HVAC duct applications. When properly installed, the tube draws an air sample from across the full width of the duct and directs it through the SL-2000 smoke detector’s sensing chamber, ensuring reliable and timely detection of airborne smoke particles and combustion byproducts.
Key Features
- 2.5-foot (30-inch) sampling tube length
- Compatible with York SL-2000 series duct smoke detectors
- Designed for HVAC ducts 12 inches to 3 feet wide
- Enables early detection of smoke and products of combustion in moving airstreams
- Helps protect HVAC systems and building occupants from fire hazards
- Engineered for straightforward installation within ductwork
Application
The S1-STN-2.5 sampling tube is intended for use in HVAC air distribution systems where continuous air movement makes early smoke detection essential. By sampling air directly from the duct interior, the tube allows the SL-2000 detector to identify the presence of smoke before it can spread throughout a building’s ventilation system. This makes it an important component in fire safety and life safety systems for commercial and residential buildings.
