The REGIN HVAC PRODUCTS, INC. S104 is a pack of five smoke emitters designed for testing and verifying smoke detection systems in HVAC applications. Each emitter produces a controlled smoke output with a 2.5-minute burn time, giving technicians a consistent, timed smoke source for detector sensitivity checks and duct smoke detector commissioning. These emitters are a standard tool for HVAC service professionals performing installation verification, routine maintenance, or code compliance testing on air-handling systems.
The S104 smoke emitters are used in residential and commercial HVAC settings where duct smoke detectors, air-sampling detection systems, or smoke control systems require functional testing. Technicians introduce smoke at the detector inlet or sampling point to confirm alarm activation and proper system response. The 2.5-minute burn duration provides adequate coverage for most single-detector tests without generating excessive residue in the ductwork.
Designed as a general-purpose smoke source for functional testing of duct-mounted and air-sampling smoke detectors in HVAC detection accessory applications.
Smoke emitter testing is performed by licensed HVAC technicians or fire alarm service professionals in accordance with NFPA 72 and the equipment manufacturer's commissioning procedures. Before testing, notify building occupants and coordinate with the fire alarm monitoring station to prevent unintended emergency dispatch. Use emitters only in ventilated conditions and follow all local codes regarding detector testing and smoke introduction into air-handling systems. Dispose of spent emitters according to local regulations.
