DUCT SMOKE DETECTOR VSD 301, DUCT SMOKE DETECTOR VCP, VCP DUCT SMOKE DETECTOR , VCP VIETNAM, VCP SWEDEN VIETNAM
VCP duct smoke detector VSD-301 has been developed from a proven design using modern devices to provide effective and reliable detection of smoke in ventilation systems.
Detection of smoke for true duct smoke detector VSD-series is achieved by monitoring a carefully controlled infrared beam (IR-detection, obscuration) within a perforated tube which is inserted into the ductwork. This method senses smoke directly within the duct, eliminating the problems associated with conventional detectors mounted in sampling boxes.
Circuitry incorporated in the design of the true duct smoke detector controls the infrared beam continuously. This ensures that the true duct smoke detector response will remain constant throughout operation of the system.
