HY-C134 - The Dahua DHI-HY-C134 conventional smoke detector is designed to provide reliable fire protection thanks to 4W-B photoelectric technology with double emitter and single receiver, capable of rapidly detecting the presence of smoke. Equipped with an intelligent contamination compensation algorithm , it automatically adjusts the alarm threshold based on the level of dust present in the optical labyrinth, reducing maintenance and improving performance. The structure with anti-loosening screws simplifies installation, while the acid- and corrosion-resistant materials ensure a long life. Compatible with conventional fire control panels and compliant with the EN54-7 standard, it is ideal for hotels, offices, schools, warehouses and industrial environments. Dahua
