Properties
● Extended optical detection thanks to dual wavelengths (blue and infrared): The aspirat-
ing 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m2 (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 con-
trol 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.
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 connec-
ted 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.
The 'FXS2056ASDAsyst ToolV2' software replaces the 'FXS2055ASD Asyst Tool' soft-
ware.
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
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

Functions
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
Damage to the connection cable
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.

Service LED indicators and buttons
Flow OK
As soon as the selftest for normal operation has been completed successfully, the 'FlowOK'
LED starts to flash.
Smoke OK
As soon as the selftest for normal operation has been completed successfully, the
'SmokeOK' LED starts to flash.
Alarm
In the event of a smoke alarm, the 'Alarm' LED starts to flash.
Normalization of the airflow
To determine the nominal airflow of the detector, perform this function during commissioning.
The nominal value established during normalization of the airflow forms the setpoint value for
monitoring the airflow during normal operation.
To perform this function, use a thin object (such as a paper clip or a watchmaker's screw-
driver) to press the button in the opening.
Once you have finished with this function, press the button in the opening again.
The smoke detector uses standard values for monitoring during normalization.
Normalization of the smoke density
To determine the nominal air quality in relation to the smoke density, perform this function
during commissioning. The nominal value established during normalization forms the set-
point value for monitoring the smoke density during normal operation.
To perform this function, use a thin object (such as a paper clip or a watchmaker's screw-
driver) to press the button in the opening.
Once you have finished with this function, press the button in the opening again.
The smoke detector uses standard values for monitoring during normalization.
The detector provides information about the current normalization process via FDnet/C-
NET (no distinction is made between smoke and airflow).
Reset button
Use the reset button to reset all of the detector's status indicators. These indicators can refer
to fire alarms or airflow events. Resetting the fire alarm also resets the associated relay.
If the detector is operated on the FDnet/C-NET, the alarms and the associated relays are
not reset.
USB connection
You can use a mini USB cable to connect the detector to a Windows PC. To set up the de-
tector, use the configuration tool 'FXS2051ASD Configuration Tool'.
Test function LED
Hold the 'Buzzer silence' button down for 5seconds. The LEDs on the display are tested
with 3 different brightness settings.
