Use

● Extended optical detection thanks to dual wavelengths (blue and infrared): The
aspirating smoke detectors FDA241 and FDA221 use dual-wavelength technology to
trigger an alarm at the earliest possible moment. They are designed to protect small and
medium-sized business-critical environments for monitoring areas of up to 800 m

(FDA241) or 500 m2 (FDA221). The detectors continually suck in air through a pipe
system via their aspirating holes. The air is fed into a uniquely designed detection
chamber, in which tiny smoke particles are detected by scattered light.

● Lower mounting and service costs: The aspirating smoke detectors FDA241 and
FDA221 can be used on an FDnet/C-NET detector line. For this purpose, communication
transponder FDCC221S is required.

● Configuration using the USB interface or the control panel via FDCC221S (optional): All
detector configurations, maintenance work, and alarm and fault management processes
can be carried out at a central location – the fire control panel. This ensures better
control while also reducing the costs of the overall solution.

● 'Out-of-the-box' mounting and commissioning: Installation is simple thanks to combined
functions for normalizing smoke values and airflow, as well as appropriate presettings for
alarm and fault thresholds.

● ASD filter box FDAZ292 available as an accessory: Dust and other dirt is filtered out of
the aspirated air and does not get into the aspirating smoke detector. The filters in the
ASD filter box are easy to replace.

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.

software.

Examples of application

● Cavities such as false ceilings or false floors

● Clean rooms

● Rooms the height of which is greater than that permitted for point detectors

● Rooms with electromagnetic fields which influence the function of point detectors

● Large rooms up to 800 m²

● Separate monitoring of control cabinets and electronics cabinets

● Data centers

● Telecommunication centers

● Mounting lines

● Cable tunnels

● Conveyor belts

Functions

Applications with a filter box

● Rooms with polluted air, in which the pollution has impaired the performance of optical
point detectors

● Mounting lines

● Recycling facilities

● Cement factories

● Mining industry

● Subway stations

● Agricultural operations

● All other applications with visible dust load

Indication

The display contains clear, comprehensible bar graphs for smoke and airflow, as well as an
alarm indicator, an error indicator, and a dust indicator (FDA241).

When the housing cover is open, the operator has access to the 'Reset', 'Normalize Smoke',
and 'Normalize Flow' functions, as well as the mini USB connector.

CAUTION

In order to prevent damage to the connection cable when positioning the housing cover,
make sure that the connection cable has been routed correctly.

The service area for the detector can be accessed in two ways.

● Partial access:
– Remove the two screws on the top of the detector.
– Slide the housing cover up until you hear it snap into place.

● Full access:
– Remove the two screws on the top of the detector.
– Slide the housing cover up until you hear it snap into place.
– Pull the housing cover out slightly at the sides and lift it up.
– Remove the housing cover.
