Duct Smoke Sampling Detector

The Duct Smoke Sampling Detector from Agni Instruments Engineers India Pvt. Ltd. is a specialized fire detection device meticulously designed to detect smoke and combustion particles within HVAC duct systems. It continuously samples airflow through specially positioned tubes inside ducts to identify smoke at the earliest stage of fire development. When smoke levels exceed preset thresholds, the detector instantly notifies the fire alarm control panel and can trigger the automatic shutdown of fans or dampers to prevent smoke circulation throughout the building. Built to comply with international standards such as NFPA 90A, this detector is ideal for large air handling systems where conventional detectors are less effective. Featuring advanced photoelectric technology, remote test and reset functions, and easy installation even in hard‑to‑reach spaces, the Duct Smoke Sampling Detector from Agni Instruments Engineers India Pvt. Ltd. guarantees reliable, efficient, and code‑compliant fire protection for commercial and industrial facilities.
