System Sensor DH400OE-1 Weatherproof Duct Smoke Detector Enclosure

Ensure uninterrupted, code-compliant smoke detection in exposed locations with the System Sensor DH400OE-1 weatherproof duct smoke detector enclosure. This purpose-built fire mounting enclosure converts indoor-rated duct smoke detectors for reliable outdoor use, protecting sensitive detection components from rain, sleet and snow while preventing dripping water in semi-exposed indoor areas. Constructed from rugged steel with a seamless drop-top shield, the DH400OE-1 reduces water ingress and prolongs detector lifespan. The unit supports current and legacy System Sensor duct smoke detectors and includes UL 268A-required sampling tube gaskets and a padlock provision to deter tampering — features that simplify compliance and lower maintenance risk for building owners and integrators. With a compact 12" (W) x 6" (D) x 18" (H) profile, the enclosure mounts easily on rooftops, mechanical rooms, and outdoor duct runs, integrating smoothly into fire, security and building monitoring systems. Ideal for fire protection contractors, facilities managers and security integrators, the DH400OE-1 delivers dependable environmental protection for critical smoke detection equipment. Add the DH400OE-1 to your next installation to ensure robust outdoor smoke monitoring and reliable system performance.
