Instead, ducting is safeguarded by the use of probe units, which collect air from a cross-section of the duct and pass it through a smoke detector head. In most cases, smoke or combustion products are likely to have traveled some distance, aging the smoke before reaching the probe unit. Therefore, it is usually recommended to fit an optical smoke detector, often a requirement of building regulations. The DPK6 duct probe units use Tyco 855PH and Tyco 835PH Multi-Sensor Smoke Detectors. DPK6 Duct Probe Units have been developed to detect smoke in ventilation ducts, offering significant benefits in terms of performance and installation. The system comprises only one single duct probe tube, improving efficiency and reducing installation time. The DPK6 duct smoke detector housing is designed to comply with the stringent demands of the new European standard prEN 54-27. The system meets all requirements for safe fire detection with airflow speeds from 0.5 m/s to 20 m/s. For the airflow through the adaptor to be representative of the airflow in the ventilation duct, the detector should be installed at a place where flow meters etc. are typically sited. Please refer to the mounting instructions supplied with the product.
