10.5 Aspirating smoke detector FDA221, FDA241
10.5.1 Use
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 is calculated using 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.
V2' software replaces the '
Tool' software.

detectors
● Large rooms up to 800 m²
