Gamewell FCI SL-2000-P Photoelectric Duct Detector

The Gamewell-FCI SL-2000-P is a photoelectric duct smoke detector for early smoke detection in HVAC ductwork, helping prevent smoke recirculation by triggering shutdown and alarm signaling when smoke is sensed. It supports a wide air velocity range and is designed for straightforward front access service and testing. This device is manufactured by Air Products and Controls, so it is commonly cross-referenced and sold under the Air Products Controls brand as an equivalent alternative.
