Potter PAD300-DD In-duct Photoelectric Smoke Detector

Product Description

The Potter Electric Signal Co. US PAD300-DD is an addressable in-duct photoelectric smoke detector designed for integration into HVAC duct systems as part of a life-safety installation. The PAD300-DD uses photoelectric sensing technology to detect smoke particles carried through supply or return air ducts, triggering an alarm signal back to an addressable fire alarm control panel. This type of detector is typically installed by licensed fire alarm technicians or HVAC professionals working on commercial or light-industrial projects where duct smoke detection is required by code.

The PAD300-DD is suited for aspiration-style duct smoke detection applications in commercial buildings, including offices, schools, healthcare facilities, and similar occupied spaces where HVAC systems require smoke monitoring. It is designed to mount directly to ductwork and sample airflow passing through the duct. Systems requiring addressable device communication benefit from the PAD300-DD integration with compatible addressable fire alarm loops.

Key Features

• Addressable design for direct integration with compatible fire alarm control panels
• Intended for in-duct installation in supply or return air HVAC systems
• Aspiration-category product suited for commercial life-safety applications
• Sold as a single unit (each)

Compatibility

Designed as an addressable in-duct photoelectric smoke detector for use within compatible addressable fire alarm systems. Consult the manufacturer data sheet and your fire alarm control panel documentation to confirm loop compatibility before installation.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and applicable local codes. Disconnect power to the fire alarm control panel and the associated HVAC system before mounting or wiring the detector. The detector should be positioned in the duct per manufacturer sampling tube guidelines to ensure adequate airflow across the sensing chamber. Do not energize the panel until all wiring connections have been inspected and verified.
