System overview

The Smoke Aspiration Systems comprise a detection module, housing base and pipe system.
The most important components of the Smoke Aspiration System are the sensitive detection
unit for detecting smoke aerosols and the aspiration unit with the built-in airflow sensor for
transporting the air samples and monitoring the pipe system for breakage and obstructions.
The pipe system comprises essentially pipe and fittings. The standard pipe system is made
from PVC or ABS. The pipes used for equipment monitoring should be halogen-free.
Each air sampling opening in the pipe system represents a point detector in the planning.

To guarantee reliable operation even under the most difficult conditions (clean rooms,
recycling area), there are numerous accessories available, such as air filters and water
separators (see Pipe system components, page 18 ).
