Fire Safety
Aspirating smoke detectors are used for early detection of smoke-generating fires
in rooms and equipment. They are especially suited to applications in which point
detectors are pushed to their limits, cannot be used or can only be used with
restrictions.
The aspirating smoke detector continually takes air from the monitored room using
a connected pipe system with defined aspirating holes. The air is supplied to the
detection chamber and is analyzed for smoke particles using the detector installed
there. The sensitivity of the detector can be adjusted.
The position and size of the aspirating holes are calculated with the 'FXS2056 ASD
Asyst Tool V2' software. The calculation ensures that the air passes from the
aspirating hole to the detector in the time specified and with the required calculated
sensitivity.
The 'FXS2056 ASD Asyst Tool V2' software is replacing the 'FXS2055 ASD Asyst
Tool' software.
