Fenwal Duct Detector DH-2000 Series

The SmartOne® Model DH-2000 Air Duct smoke detector is designed for detecting particles of combustion in air handling systems. Upon smoke detection the integral detection device will signal the SmartOne compatible control unit to which it is connected. The duct detector housing accepts the SmartOne Intelligent CPD-7052 ionization detectors or SmartOne Intelligent PSD-7157 Photoelectric detectors . A transparent Lexan cover over the detection chamber allows visual inspection of the duct detectors chamber and internal detector status. Sampling air in HVAC ducts is accomplished with the use of sampling tubes which extend into the HVAC duct.
