Both devices have an optical dual wavelength

Siemens Building Technologies brings two own aspiration smoke detectors on the market that accurately distinguish between smoke and interference such as steam or dust. The models FDA221 FDA241 and therefore remain under difficult conditions reliably detect and able to recognize fire. Development at an early stage
Aspiration Detectors (Aspirating Smoke Detectors; ASD) sucking through a pipe system from the detection area continuous air and examine the intake air for smoke particles. However, normal point detectors set alarm have difficulty distinguishing between dust and smoke, making set alarm them more susceptible to false alarms. Siemens Building Technologies solves this problem with ASA technology, now available in the new ASD models FDA221 and FDA241. set alarm
Both devices have an optical dual wavelength 'detection technology, which works with blue and infrared light waves. On the basis of the different wavelengths enable the detectors, the particle size and concentration, thus enabling them to distinguish it from dust. Smoke The two new aspiration detectors are easy to install and as a participant in existing Siemens fire systems such Sinteso and Cerberus Pro on the detection.
Such integration provides transparency of message display and operation. set alarm For example, detector configuration, maintenance and alarm and fault management are carried out. Directly on the fire panel This optimizes the control and reduces the cost of the solution as a whole.
Application of these ASD detectors include data rooms and elevator shafts, but also sheds a lot of dust and dirt as transshipment buildings. These two devices are particularly suitable for use in locations where the detection conditions are difficult, where an aesthetically appealing solution is desired or where a high detection sensitivity is needed. That may be the case in large areas such as entrance halls, warehouses set alarm and industrial production set alarm halls or in hard to reach areas such as ducts, underground tunnels or computer centers and cleanrooms.
