ACEND Fire Alarming Device

ACEND™ Notification Appliances are integral to the Siemens Smart Infrastructure Building System, delivering a comprehensive emergency alarm and evacuation guidance solution to enhance life safety assistance during emergencies.
Unlike traditional alarming devices, this portfolio is the first audible and visual alarm device series on the market with unique optical patents. The sophisticated lens curve optimizes light direction and intensity, ensuring prominent alarm signals and ideal compatibility for both wall and ceiling mounting. Integrated with Siemens' AI charging algorithms, this portfolio is the first in the industry to achieve a current draw below 10mA, setting a new benchmark for energy efficiency.
ACEND™ Notification Appliances excel in intelligent performance, providing advanced monitoring and iterative upgrades for reliable assistance during emergencies. The portfolio features highly sensitive sensors and intelligent circuits that monitor data in real-time, helping to predict potential issues and facilitate preventive maintenance for optimal performance. Iterative upgrades are also enabled by big data analysis. During emergencies, the appliances instantly send urgent notifications to all building occupants via the cloud, ensuring timely awareness of critical situations. Meanwhile, they provide conspicuous strobe lights and intelligent voice alerts that adapt to different emergency types and severity levels, guiding efficient and organized evacuation with clear visual and auditory signals. Moreover, the specially designed 520 Hz low-frequency sound resonates with brainwaves, offering enhanced penetration to effectively awaken individuals, even from deep sleep.
This portfolio also delivers exceptional adaptability with a modular design. Various interchangeable covers and four different LED lenses are available for users to tailor their setups to specific needs. With customizable appearances and diverse sound options (including horn, speaker, and low-frequency sounder), users can create up to 560 unique combinations, ensuring flexible adaptation to the installation requirements of different buildings.
Pioneering sustainability, ACEND™ Notification Appliances are the first audible and visual alarm device series on the market to use environmentally friendly bio-based materials, significantly reducing fossil resource consumption. This innovation significantly reduces fossil resource consumption and helps cut CO₂ emissions by 300 tons per year—equivalent to the carbon absorption of about 13,636 mature trees annually—showcasing Siemens’ strong commitment to sustainability.
