Siemens ASD FDA Series
The FDA241/221 series of detectors are a very early warning dual wavelength
(blue & infra-red) smoke detectors designed to protect small to medium, business-
critical environments up to 800 m2with the FDA241 or 500 m2with the FDA221).
The detector works by continually drawing air into sampling holes in a pipe net-
work. The air is passed into a uniquely designed detection chamber where light
scattering technology detects the presence of very small amounts of smoke.
Lower installation and service support costs
The FDA241 and FDA221 detectors can communicate directly on the
FDnet/C-NET loops (with an optional FDCC221S PCB), so there is no need for
separate relay or network connections. This reduces the cost of installation and
service. The detector acquires its loop address automatically.
Fire control panel programming (requires FDCC221S option)
The sophisticated integration on FDnet/C-NET allows for detector configurations,
maintenance and alarm/fault management to be performed centrally – at the fire
control panel. This increases control and lowers total solution cost.
Out-of-the-box operation
The FDA241 and FDA221 can be installed and commissioned out-of-the-box.
Normalize smoke density and air flow functionality, suitable default alarm and fault
thresholds makes for an easy installation.
Display
The front panel display includes an easy to read smoke
density and airflow level bar graph, alarm, fault status and
dust indicator (FDA241 only).
When the field service access cover is open, the user has
access to the Reset, Normalize Smoke & Flow buttons and
a mini USB communication connector.

Legend to Indicators
Opening the detector
There are 2 modes for accessing the detector service area.
Partial access
Remove the 2 screws on the top of the detector. Slide the front cover upward until it
reaches the self locking tabs.
Full access
Remove the 2 screws on the top of the detector. Slide the front cover upward until it
reaches the self locking tabs. Grasp the cover on the sides and gently apply pres-
sure to spread the cover sides outward. This will enable the cover to be totally re-
moved
Warning: Take notice of the front panel connecting cable if fully removing the
cover.
Service Access – Display LEDs and Buttons
Flow OK
If self check is OK the Flow OK LED starts flashing to indicate normal operation
Smoke OK
If self check is OK the Smoke OK LED starts flashing to indicate normal operation
Alarm
The Alarm LED flashes in the event of a smoke alarm
Normalize flow button
As each installation will require a different sampling pipe configuration, this function
is used to set the zero reference for the bargraph. This function is required to be
done during commissioning of the detector. The nominal flow value which is deter-
mined during the normalize flow period is then the zero set point value for the air-
flow monitoring during normal operation.
To use this function, use a thin tool such as a paper clip or a small jeweller’s
screwdriver, place the tool into the hole and push the normalize flow button.
During the Normalization period the detector is still actively monitoring for smoke
using the default values.

Normalize smoke button
This function is used to determine the nominal clean air value for the detector. This
is required to be done during commissioning. The nominal value which is deter-
mined during the normalize period is then the set point value for the smoke monitor-
ing during normal operation.
To use this function, use a thin tool such as a paper clip or jeweller’s screwdriver,
place the tool into the hole and push the normalize smoke button.
This function could be manually stopped by pressing the Normalize button again.
During the Normalization period the detector is still actively monitoring for smoke
using the default values.
Note:
The detector indicates over FDnet/C-NET) that normalizing is active (no distinguish-
ing between smoke and air flow)
Reset:
Pressing the Reset button, resets all latched states of the detector. Latched states
can be fire alarms or airflow out-of-range events. If a fire alarm is reset the associ-
ated relay is also reset.
Note:
If the detector is connected to FDnet, the alarms and associated relays are set to
non-latching
USB Connector:
The mini USB connector is used connect to a laptop when required to re-configure
the detector using the ASD Configuration Tool F-FXS2051
LED Test Function:
Press and hold the “Buzzer silence button” for 5 seconds.
The detector will cycle through a full LED display to check the operation of all LEDS
If connecting the Siemens ASD directly to a Siemens FDnet, C-NET loop, the FDCC221S communication card must
be ordered as a separate item. (S24218-A201-A2)
