Description

The Agni Universal Air Smoke Sampling Duct Detector Enclosure is designed to detect smoke within HVAC and ventilation ducts before smoke can spread to other areas of a building. Installed directly onto air ducts, the enclosure continuously samples the airflow through specially designed inlet and outlet tubes, allowing the installed smoke detector to monitor for smoke particles within the ventilation system. This early smoke detection arrangement helps prevent smoke generated by a fire from being circulated through air-conditioning and ventilation ducts into otherwise unaffected areas of a facility. The enclosure supports both conventional and intelligent addressable smoke detectors, providing flexible integration with a wide range of fire alarm systems. Constructed from high-strength ABS plastic, the enclosure features a transparent front cover that allows convenient visual inspection of the installed smoke detector without opening the housing. Designed for HVAC environments, the enclosure is suitable for airflow speeds ranging from 0.2 m/s to 20 m/s, making it suitable for applications including commercial buildings, hospitals, shopping malls, factories, and large infrastructure projects. The unit includes a 250 mm sampling tube as standard, with additional tube lengths available for wider air ducts. The sampling tubes help provide appropriate airflow through the detector chamber for effective smoke detection. ________________________________________ Key Features: • Universal air smoke sampling duct detector enclosure • Designed for HVAC and ventilation duct smoke detection • Continuously samples airflow inside air ducts • Helps detect smoke before it spreads through ventilation systems • Supports conventional smoke detectors • Supports intelligent addressable smoke detectors • High-strength ABS plastic construction • Transparent front cover for easy detector inspection • Suitable for a wide range of HVAC airflow conditions • Operating airflow range of 0.2 m/s to 20 m/s • Supplied with 250 mm sampling tube • Additional sampling tube lengths available for wider ducts • Suitable for commercial, industrial, healthcare, and infrastructure applications ________________________________________ Technical Specifications: • Product Type: Air Smoke Sampling Duct Detector Enclosure • Application: HVAC & Ventilation Duct Smoke Detection • Construction: High-Strength ABS Plastic • Front Cover: Transparent • Compatible Detector Types: Conventional Smoke Detectors / Intelligent Addressable Smoke Detectors • Airflow Range: 0.2 m/s to 20 m/s • Standard Sampling Tube Length: 250 mm • Additional Tube Length: Available for Wider Ducts • Installation: Directly on HVAC / Air Ducts • Smoke Detection Method: Air Sampling Through Inlet & Outlet Tubes • Application Environment: HVAC Systems • Suitable For: Commercial, Hospital, Shopping Mall, Factory & Large Infrastructure Projects ________________________________________ How It Works: 1. Installation on Air Duct: The enclosure is mounted directly onto the HVAC or ventilation duct. 2. Air Sampling: Specially designed inlet and outlet tubes continuously draw and pass air from the duct through the detector chamber. 3. Smoke Detection: The installed compatible smoke detector monitors the sampled airflow for smoke particles. 4. Early Detection: When smoke is detected within the ventilation system, the connected fire alarm system can respond before smoke is circulated to other areas of the building. ________________________________________ Applications: Suitable for: • HVAC Systems • Air Conditioning Ducts • Ventilation Systems • Commercial Buildings • Hospitals • Shopping Malls • Factories • Industrial Facilities • Large Infrastructure Projects • Building Fire Safety Systems ________________________________________ Product Benefits: Early Smoke Detection: Detects smoke within ventilation ducts before it can spread to other areas.
