The Automation Components Inc (ACI) 128328 Smoke Detector Duct NEMA 4X is a duct-mounted secure system designed to monitor airflow within ventilation systems for the presence of combustion particles. When abnormal conditions are detected, it sends a signal to the connected control equipment to trigger the proper system response. Commonly installed in commercial and HVAC systems, it supports protection by monitoring air handling ductwork during normal operation. As an integral part of the ventilation control system, it assists coordinate equipment shutdown or other programmed actions to limit the movement of contaminated air throughout the facility.
