Description

The ST-3TA is an electronic component model belonging to the category of trimmer potentiometers. It is designed for use in various applications, including HVAC systems. The ST-3TA features low-flow technology, allowing it to detect smoke at air speed velocities ranging from 100 to 4,000 feet per minute (0.5 to 20.32 m/sec.). It ensures reliable performance even in high airflow environments. The ST-3TA is equipped with a patented telescopic sampling tube and easily accessible code wheels for addressing the detector. It can be mounted on round or rectangular ducts from 1' to 12' (0.3 to 3.7 meters) wide and has outside mounting tabs for convenient installation. The transparent cover allows for visual inspection.

Application Scenarios

The ST-3TA trimmer potentiometer is suitable for use in duct smoke detection systems for HVAC applications. It provides an effective solution for detecting smoke in a wide range of airflow environments. However, it is important to note that duct smoke detectors are not substitutes for open-area smoke detectors, early warning detection systems, or a building's regular fire detection system. For more information on the proper use of smoke detectors in duct applications, please refer to Gamewell's application guide.
