Description
The System Sensor D4120-Photoelectric Duct Smoke Detector is used in HVAC systems to detect the existence of smoke in the airflow. It powered by 24V AC/DC or 120V and can be easily installed in commercial and industrial ventilation systems. It uses photoelectric technology to sense smoke at its early stage and alerts by ringing bells to prevent the fire from extending to ducts. It is compatible with air-handling equipment and helps to increase safety by giving timely signals. It is designed in such a way that it will not produce false alarms but will perform its functions effectively.
