Industrial ESDST Photoelectric Duct Smoke Sensor, model EST ESD-ST ESDST, is a duct-mounted smoke detector that uses photoelectric sensing to detect smoke in ventilation air. It features a four-wire terminal block (TB) connection for power and signaling, enabling straightforward wiring into industrial monitoring circuits. Designed for HVAC duct installations in industrial environments, it provides rapid smoke detection along moving air paths while fitting standard ductwork configurations.
