Potter Electric Signal pad300-ductr Duct Smoke Detector

Product Description

The POTTER ELECTRIC SIGNAL pad300-ductr is an analog addressable duct smoke detector designed to meet NFPA requirements for duct smoke detection applications. Air sampling is performed by two tubes that extend directly into the duct, drawing air across the detector chamber for continuous monitoring. The unit ships with an exhaust tube of one standard length included in the installation kit. Sampling intake tubes are ordered separately in three standard lengths: 2.5 feet, 5 feet, and 10 feet, and are cut to size on the job to match the duct width. This detector is installed by licensed fire alarm technicians and HVAC professionals as part of a larger analog addressable fire alarm system.

The pad300-ductr is suited for installation in commercial and industrial HVAC duct systems where smoke detection is required by code. It is commonly installed in air handling units and supply or return ductwork where early smoke detection is critical to system shutdown and occupant safety. The detector integrates into analog addressable fire alarm control panels, providing point identification and status reporting. The clear cover design and capture screw retention allow technicians to mount and service the unit efficiently without full disassembly.

Key Features

• Analog addressable design integrates with compatible fire alarm control panels for point-level identification
• Dual air sampling tubes extend into the duct for representative air sampling across the duct cross-section
• Sampling intake tubes available in 2.5-foot, 5-foot, and 10-foot lengths and field-cut to match duct width
• Exhaust tube of one standard 7-inch length included in the installation kit
• Mounting template and two sheet metal screws included for straightforward duct surface installation
• Clear cover secured by four capture screws allows mounting and access without full cover removal
• Designed and built to meet NFPA regulations for duct smoke detectors

Compatibility

Designed as an analog addressable duct smoke detector for use in commercial and industrial HVAC duct systems requiring NFPA-compliant smoke detection. Specific compatible fire alarm control panels and addressable loop modules were not provided in the product data; consult POTTER ELECTRIC SIGNAL documentation to confirm panel compatibility before installation.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72, NFPA 90A, and all applicable local codes. Disconnect power to the fire alarm panel loop and the HVAC system before beginning installation. Use the included mounting template and sheet metal screws to secure the housing to the duct surface; intake sampling tubes must be measured, ordered in the appropriate standard length, and cut to fit the duct width before final mounting. Do not energize the device or restore HVAC airflow until the sampling tubes are fully seated, all wiring terminations are verified, and the system has been tested per the authority having jurisdiction.
