Potter PAD200-DUCTR Analog Addressable Duct Detector
Overview
The Potter PAD200-DUCTR is an analog addressable duct detector designed for integration into fire alarm systems monitoring HVAC ductwork. This detector leverages analog addressable technology to provide real-time smoke detection data directly to compatible fire control panels, eliminating the need for conventional relay modules and simplifying system architecture. The PAD200-DUCTR combines reliable smoke sensing with addressable reporting, making it suitable for retrofit and new construction installations where duct-mounted fire detection is required.
Key Features
- Analog Addressable Technology: Transmits continuous smoke level data to the control panel, enabling early warning detection and reducing false alarm susceptibility compared to conventional detectors
- Duct-Mount Configuration: Purpose-built for direct installation in HVAC supply or return ductwork, monitoring air volume at the source
- Intelligent Smoke Sensing: Responds to visible smoke particles in airstream, with analog output proportional to smoke concentration
- Direct Panel Integration: Compatible with addressable fire control panels that support analog input protocols, reducing auxiliary modules
- Compact Design: Engineered for minimal obstruction in duct runs while maintaining effective sensing coverage
- Standard Fire Alarm Compatibility: Works within conventional addressable fire alarm system wiring and communication protocols
Integration & Compatibility
The PAD200-DUCTR integrates into analog addressable fire alarm systems as a direct-wired smoke sensing device. When properly configured on a compatible control panel, the detector reports smoke conditions as an analog signal, allowing the panel to trend detection patterns and respond with graduated alert levels. This capability makes the PAD200-DUCTR suitable for facilities requiring early-warning HVAC monitoring in commercial, institutional, and industrial environments. Installers should verify panel compatibility with analog addressable duct detectors before specification.

As a systems engineer responsible for fire alarm design and integration, I've found that analog addressable duct detectors like the Potter PAD200-DUCTR simplify HVAC monitoring in multi-zone facilities. The PAD200-DUCTR's direct analog reporting reduces panel load compared to running separate detector circuits, and the duct-mount form factor ensures you're sampling air at the point of circulation rather than trying to infer duct conditions from remote locations.
Technical Highlights:
- Analog Reporting: Transmits proportional smoke signal directly to panel, enabling detection before alarm threshold and supporting maintenance diagnostics
- Duct Integration: Mounted inline or in probe configuration within HVAC system, captures smoke in supply or return air stream
Deployment Considerations:
- Verify duct airflow velocity and temperature range compatibility; high-velocity ducts may require probe extensions or protective sleeves
- Plan wiring runs to minimize voltage drop on analog circuits; use twisted-pair shield recommended for addressable sensor networks
For buildings with ducted HVAC and addressable fire systems, the PAD200-DUCTR delivers effective early-warning smoke detection without requiring relay conversion modules. Confirm panel firmware supports analog duct detector addressing during system design phase.
