AD-10-1980 is a Wagner TITANUS® sound absorber/muffler unit designed for use with aspirating smoke detection (ASD) systems. Installed on the exhaust outlet of compatible TITANUS aspirating detectors, the unit reduces operational noise generated by the air sampling fan, making it ideal for noise-sensitive environments such as offices, data centres, control rooms, libraries, healthcare facilities, and other occupied spaces. It is used as an accessory within Wagner air sampling smoke detection systems to provide quieter operation while maintaining effective airflow performance.
