Potter PAD200-DUCT Duct Smoke Detector

Product Description

The POTTER ELECTRIC SIGNAL CO. US PAD200-DUCT is a duct-mounted smoke detector designed for integration into HVAC air handling systems to detect smoke carried in moving airstreams. The unit samples air drawn from supply or return ductwork and triggers an alarm signal when smoke particulates are present, allowing building automation or fire alarm control panels to shut down air handlers and prevent smoke from circulating through a structure. It is installed by licensed fire alarm technicians and HVAC professionals working on commercial and light-commercial buildings subject to life-safety codes.

The PAD200-DUCT is suited for installation in supply and return air ducts in commercial, institutional, and light-industrial buildings where NFPA 72 and NFPA 90A require duct smoke detection. Typical applications include air handling units, rooftop package systems, and large-scale HVAC systems where smoke migration through ductwork poses a life-safety risk. The detector is intended for use in new construction and retrofit projects where duct smoke detection is mandated by the authority having jurisdiction.

Key Features

• Duct-mounting design samples airstreams in supply and return HVAC ductwork
• Integrates with fire alarm control panels to initiate system shutdown or alarm response
• Packaged as a single unit (sold individually) for straightforward procurement
• Categorized within the duct and beam detector product family for code-compliant life-safety applications

Compatibility

Designed as an OEM-style duct smoke detector for installation in commercial HVAC air handling systems where duct smoke detection is required by applicable fire and mechanical codes.

Installation Notes

Installation must be performed by a licensed fire alarm technician or qualified HVAC professional in accordance with NFPA 72, NFPA 90A, and all applicable local codes. Disconnect power to the air handling unit and de-energize the fire alarm control panel circuit before beginning installation or wiring. Do not install in duct locations where airflow velocity or temperature falls outside the manufacturer specifications stated in the product datasheet. Coordinate with the authority having jurisdiction to verify placement meets detection coverage requirements prior to commissioning.
