The DS duct smoke detector is used to detect fire in the early stages of its development spreading in ventilation ducts. It has an optical smoke sensor that enables quick and reliable detection of fire. The device is equipped with a double-sided
short circuit isolator that ensures continuous loop operation despite a short circuit on the line and enables easy location of damage. Additionally, the detector monitors the level of contamination, sending information to the control panel about the possible need to clean or replace the element. The level of contamination is also included in the detection algorithm, thus increasing the certainty of fire detection.
