EBDDHN
Smoke detection in ventilation ducts prevents smoke and toxic gases from spreading between compartments, reducing risks for occupants. These devices enable the use of point detectors without installing them directly inside the duct, where high air velocity would otherwise impair their performance.
EBDDHN Universal duct adapter
The EBDDHN duct adapter is designed to accommodate any smoke detector, whether analog‑addressable or conventional. The detector’s mounting base can be secured using the two included screws, while the integrated terminal block simplifies wiring and reduces installation time. A versatile and reliable solution for integration into fire detection systems.
Smoke detection in air ducts using the Venturi principle
By continuously sampling the airflow inside heating and ventilation ducts, the EBDDHN adapter enables early detection of smoke in industrial and commercial environments. Based on the Venturi principle and compatible with sampling pipes of different lengths, it ensures reliable operation with air velocities ranging from 0.5 m/s to 20 m/s.
