The SD-PH protective housing keeps Kidde SuperDuct duct smoke detectors operating reliably in high-humidity environments where condensation would otherwise compromise detector performance. It insulates the detector and circulates sampled air from the monitored HVAC duct, preventing moisture buildup on sensing elements.
Built for tough HVAC environments
Designed for installations where the SuperDuct detector sits near unconditioned air - loading docks, mechanical rooms, rooftop air handlers, and similar spaces. The weatherized enclosure stops condensation from triggering nuisance alarms or degrading detector sensitivity over time. A hinged, transparent cover keeps status indicators visible and gives you full access for testing and maintenance without removing the housing.
Key features
- Eliminates condensation-related nuisance alarms in high-humidity duct smoke detection installations
- Transparent hinged cover keeps status LEDs visible and allows quick access for inspection and service
- Compatible with both SuperDuct models: Four-Wire (SD-4W) and Two-Wire (SD-2W) duct smoke detectors
- Physical damage protection for detectors installed in exposed or high-traffic mechanical areas
- Circulates sampled air from the HVAC duct through the housing, maintaining detector performance
Compatibility
The SD-PH mounts directly with Kidde SuperDuct Four-Wire (SD-4W) and Two-Wire (SD-2W) duct smoke detectors. Air sampling tubes connect the housing to the monitored HVAC duct. Weatherized against outdoor air intrusion but not rated for direct outdoor exposure.
