ASD - aspirating smoke detection

Invisibly efficient

Aspirating smoke detectors continuously draw air samples from the areas requiring protection and evaluate them for the presence of smoke. They ensure reliable fire detection in demanding application areas, where earliest possible fire detection is essential and business continuity is paramount.

Product information

Innovative technology and outstanding reliability

The aspirating smoke detectors FDA221 and FDA241 from Siemens use two wavelengths to differentiate between smoke and deceptive phenomena. This enables increased detection reliability even in the most demanding environments. In addition, FDA221 and FDA241 can be directly integrated into a fire protection system from Siemens.
Application areas

Aspirating smoke detection for special applications

Aspirating smoke detectors are primarily used in areas where point detectors cannot, or have a limited usage. These include inaccessible or restrictive areas like operating rooms, invisible detection in historical buildings, concealed detection e.g. in metro stations, parking garages or prisons.
