2.2 Safety regulations for the method of operation
National standards, regulations and legislation
Siemens products are developed and produced in compliance with the relevant
European and international safety standards. Should additional national or local
safety standards or legislation concerning the planning, assembly, installation,
operation or disposal of the product apply at the place of operation, then these
must also be taken into account together with the safety regulations in the product
documentation.
Electrical installations
WARNING
Electrical voltage
Electric shock
z Work on electrical installations may only be carried out by qualified
electricians or by instructed persons working under the guidance and
supervision of a qualified electrician, in accordance with the electrotechnical
regulations.
z Wherever possible disconnect products from the power supply when carrying
out commissioning, maintenance or repair work on them.

‒ Only check controls up to the interface (relay with blocking option).
‒ Make sure that only the controls to be tested are activated.
z Inform people before testing the alarming control devices and allow for possible
panic responses.
z Inform people about any noise or mist which may be produced.
z Before testing the remote transmission, inform the corresponding alarm and
fault signal receiving stations.
Modifications to the system layout and products
Modifications to the system and to individual products may lead to faults,
malfunctioning and safety risks. Written confirmation must be obtained from
Siemens and the corresponding safety bodies for modifications or additions.
Modules and spare parts
z Components and spare parts must comply with the technical specifications
defined by Siemens. Only use products specified or recommended by
Siemens.
z Only use fuses with the specified fuse characteristics.
z Wrong battery types and improper battery changing lead to a risk of explosion.
Only use the same battery type or an equivalent battery type recommended by
Siemens.
z Batteries must be disposed of in an environmentally friendly manner. Observe
national guidelines and regulations.
Disregard of the safety regulations
Before they are delivered, Siemens products are tested to ensure they function

3.2.1 C-LINE
The C-LINE detectors are characterized by a very high detection reliability
combined with a high immunity to deceptive phenomena. The detectors have two
parameter sets, by means of which they can be adapted to the conditions
prevailing at the installation location.

Selection of parameter
The signals captured by the sensor technology are transmitted to the algorithm.
The algorithm analyses and evaluates the course of the signals (signal intensity,
rate of rise and fluctuation). The algorithms are set by selecting the parameter set,
which sets the detectors to the expected types of fire and ambient influences.

3.2.2 S-LINE
Properties
In contrast to the C-LINE detectors, S-LINE detectors have the following features:
z Dynamic influence on the parameter sets
z Pattern recognition
z Real time interpretation of the situation
z Process- and time-controlled switchover of the parameter sets
Signal processing of the S-LINE detectors is based on ASAtechnology (ASA =
Advanced Signal Analysis). ASAtechnology can also be characterized as second
generation algorithms. Signal processing with ASAtechnology permits optimum
adaptation of the detector behavior to the particular ambient conditions.
S-LINE detectors are characterized by their unique detection reliability and high
immunity to deceptive phenomena.

interpretation of the situation leads to a dynamic influence on the algorithm. This
results in a broadening of the application range of the parameter set and thus of
the detector. The detector reacts more sensitively in the event of fire, and more
robustly in the event of deceptive phenomena.
Switching over the parameter set
In addition to the selection of the parameter set, the S-LINE detectors enable timeor process-controlled switching over of the parameter sets (Manned/Unmanned
switchover). Thanks to this function, the detector can be used in places where the
situation changes regularly and frequently (e.g. kitchen, production hall).
Downloadable parameter sets
Detectors of the S-LINE have several permanently programmed parameter sets.
For special applications new, additional parameter sets can be downloaded in the
field (depending on the control panel).

3.3 Detectors
3.3.1 Neural fire detector
The neural fire detector is a multiple criteria fire detector and is equipped with two
optical and two thermal sensors. The following neural fire detectors are available:
z FDOOT241-9
z FDOOT241-8
z FDOOT221
The following table shows the most important differences between the neural fire
detectors.

The detector has a sophisticated opto-electronic measuring chamber with two
optical emitters, an optical receiver and two thermal sensors.
The transmitters illuminate the smoke particles from different angles. One sensor
acts as forward scatterer, the other as backward scatterer. The scattered light then
hits the receiver (photodiode) and generates a measurable electric signal.
The combination of a forward and backward scatterer facilitates an optimum
detection and the differentiation of light and dark particles, which leads to a
homogenous response behavior and optimizes the differentiation of wanted signals
and deceptive phenomena.

Building Technologies 007004_k_en_--
Fire Safety & Security Products 16.04.2009
In addition, the heat sensors make it possible to detect fires without smoke
generation.
The combination of optical and thermal sensor signals optimizes detection
reliability. This has the following advantages:
z Early detection of all types of fire, whether they generate light or dark smoke, or
no smoke at all.
z The neural fire detector can be operated at a lower sensitivity level and thus
achieves a higher immunity against false alarms which may otherwise be
caused by cold aerosols (e.g. by smoking, electrical welding, etc.). In the case
of an open fire, the smoke sensitivity is heightened by the temperature
increase, which means that a detection reliability level that is comparable to
that of the wide-spectrum smoke detector can be achieved.
The neural fire detectors FDOOT241-8/9 may as well be applied either as optical
smoke detectors or as out-and-out heat detectors. This is possible by selecting one
of the following sensor modes (with the detector exchanger and tester or on the
control panel):
z Sensor mode 0: Application as neural fire detector
z Sensor mode 1: Application as heat detector
z Sensor mode 2: Application as smoke detector
In sensor mode 1 or 2 the parameter sets of the heat detector FDT241 or of the
wide-spectrum smoke detector FDO241, respectively, can be selected. Then,
these neural fire detectors behave like the heat detector FDT241 or smoke detector
FDO241.
3.3.1.1 Variants of the FDOOT241-9
The neural fire detector FDOOT241-9 is available in three different variants A, B
and C. The compatibility differs depending on the variant. The following table
provides an overview of the compatibility of the different variants. Refer to
document 008331 'List of compatibility' for compatibility details.

3.3.2 Wide-spectrum smoke detector
The wide-spectrum smoke detector is an optical smoke detector with an optical
sensor. It works according to the principle of forward scattering. This detector
reacts with extreme sensitivity to light fire aerosols. The following wide-spectrum
smoke detectors are available:

3.4 Function
3.4.1 Parameter sets
The parameter sets influence the detection behavior of the detectors and
specifically set them to the expected fire phenomena and ambient influences in the
environment to be monitored.
All parameter sets are programmed in the detectors. During commissioning, the
optimum parameter set must be selected for the conditions at the place of
installation. On a FDnet detector line, this is carried out at the control panel. On a
collective or MS8 detector line this is done with the detector exchanger and tester.
On a FDnet detector line, the parameter set must always be set explicitly. Unless a
parameter set is selected in collective or MS8 operation, the detector works with
the default parameter set '0'. In this case the number of the selected parameter set
is always '0'.

tor [J 42]

moke detector [J 49]

3.4.2 Danger levels
The detector's signal processing efficiently distinguishes between fire events and
deceptive phenomena. The basis for reaching a danger level is not only given by
measured values exceeding a "response threshold"; moreover, the smoke density
progression is observed over a longer period of time and assessed by the
algorithms.
Fire detectors can transmit the following danger levels to the control panel:
Danger level Meaning Comment
0 No danger Normal condition
1 Check situation A different parameter set should
potentially be selected (inappropriate
application)
2 Warning Possible danger
3 Alarm Fire
Notes
z The evaluation of the danger level and the decisions to be taken (e.g. activation
of remote transmission) are configured in the control panel.
z On a collective line only the danger levels 0 and 3 can be transmitted to the
control panel.

3.4.3 Diagnosis levels
For the most part, the detector monitors its function by itself. The signals of all
sensors are permanently monitored. In particular, the temperature sensors, light
emitters, and light receivers are monitored to ensure that they are functioning
correctly. Signal processing takes account of the monitoring results and adapts its
behavior accordingly.
The following diagnosis levels are derived from the different control measurements:
z Normal
z Observe information
z Replacement recommended
z Replacement necessary
z Fault
See the table below for details.
A fault message is signaled in the event of a fatal error that makes the proper
function of the detector impossible. To correct the cause of the fault, additional
information is available in the detector. This information may be displayed, for
example, by the detector exchanger and tester FDUD29x (for details see
documents 007227 and 009718).

3.4.4 Line separator
All FDnet devices are equipped with a line separator.
The FDnet device is equipped with electronic switches which isolate the defective
part in case of a short-circuit on the detector line. The rest of the detector line
remains serviceable. On a loop line all FDnet devices remain fully functional after a
simple error.
3.4.5 Automatic recognition of the detector line protocol
The two multiple protocol detectors FDOOT241-9 and -8 may communicate via
different detector line protocols. These detectors recognize the protocol on the
detector line (e.g. FDnet or collective) and automatically switch to the protocol in
question. This functionality facilitates commissioning in case of modernization, as
no actions need to be taken on the detector itself. See document 008331 'List of
compatibility' for exceptions.
3.4.6 Internal alarm indicator
The detectors have an internal alarm indicator. The internal alarm indicator shows
the operating condition of the detector (see table).
Operating condition Flashing mode of the AI
Normal AI flashes weakly every 4 seconds
Test AI flashes weakly every 0.5 seconds
Alarm AI lights up every second
3.4.7 Connection of external alarm indicators
Two external alarm indicators can be connected to every detector. In the FDnet the
alarm indicator can be connected to any detector; activation of the alarm indicator
can be programmed in the control panel.
Instead of an optical alarm indicator that flashes in the event of an alarm, the
sounder base is provided with an acoustic alarm indicator.

3.4.8 Renovation mode
Renovation mode should be selected when work that generates a lot of dust or
aerosols is being performed in the room.
In renovation mode, the neural fire detector and the heat detector only trigger alarm
when the temperature exceeds 80 °C for 20 seconds.
The wide-spectrum smoke detector does not trigger alarms in renovation mode
but continues to work normally.
3.4.9 Test mode
For testing purposes the detectors can be set to test mode. In test mode the
detectors react faster and with a higher sensitivity level. All detectors can be tested
with the detector exchanger and tester FDUD29x. Optical detectors may also be
tested with the test gas REF 8 or REF 8-S. Heat detectors can be tested with a hot
air fan.

Testing detectors [J 81]
3.4.10 Behavior in degraded mode
If the main processor of the fire control panel fails, the control panel enters
degraded mode operation. Depending on the control panel, the fire control panel
may continue to provide the main alarming functions and signaling functions in
degraded mode operation.
Characteristics of degraded mode operation on control panels supporting degraded
mode operation:
z Alarming is still ensured in degraded mode operation. However, in degraded
mode operation, only collective alarming is possible. This means that in the
event of an alarm, it is possible to identify the detector line but not the exact
location of the detector triggering the alarm.
z If a sounder base is connected to the output for the external alarm indicator, it
is activated in degraded mode operation if there is a fire alarm (only with
detectors and sounder bases with ES ≥ 30); configuration for a specific control
panel is possible.
z When the connection for the external alarm indicator is used for a control
function (e.g. hold-open system), the output assumes the configured fail-safe
position (only with detectors with ES ≥ 30); configuration for a specific control
panel is possible.
Degraded mode operation on the FDnet is not supported in the same way by all
control panels. During planning, observance of the information in document
008331 'List of compatibility' and the respective control panel documentation is
therefore mandatory.

3.4.11 Interface to service devices
All point detectors have a non-contact interface to the detector exchanger and
tester FDUD29x (service device for commissioning and maintenance). The
detector exchanger and tester communicates with the detector via this interface
(MC link). Detailled information is listed in the operating instructions for the detector
exchanger and tester (see documents 007227 and 009718).

The line tester FDUL221 is able to recognize and localize the following errors on
the FDnet:
z Wiring error
z Open line
z Short-circuit
z Ground fault
In addition, the line tester recognizes the devices connected to the FDnet detector
line. For details, see document 008250.

3.5 Mechanical setup
To install a point detector, a detector base is always required. After mounting the
detector base the point detector is simply screwed into the base by hand with the
detector exchanger or with the detector exchanger and tester.
Properties
z Quick installation and reliable contact due to screwless terminals
z Insertion of the insulated wires without any tools
z The centered alarm indicator makes an alignment of the detector base
superfluous
z Space for up to 6 auxiliary terminals for detector heating units etc.
A wide range of accessories that can be combined for the corresponding
application is available for the different applications.

4.1 Compatibility
All detectors can be operated on the FDnet detector line. The neural fire detector
FDOOT241-9 may also be operated on a collective detector line and the
FDOOT241-8 may be operated on an MS8 detector line (for details, please refer to
document 008331).
4.2 Ambient features
In selecting the optimum parameter set, the following factors must be taken into
account:
z Risk of injury to persons
z Concentration of valuable items
z Room geometry
z Deceptive phenomena
z Risk of fire
z Critical fire size
Risk of injury to persons
People are extremely endangered in localities such as concert halls, nursing
homes or hospitals. The risk of damage to persons is thus very high in these
localities. In canteen kitchens the situation is different. Few people work in such
facilities and are able to save themselves in the event of timely alarms. The risk of
injury to persons is thus rather low in this case.
Concentration of valuable items
Irreplaceable cultural assets are often on display in museums. Computer centers
house servers with large data volumes. The concentration of valuable items is
rather high. In a normal hotel room the concentration of valuable items must be
classified as low.
Room geometry
High ceilings, complex room shapes or well ventilated rooms have a complex room
geometry. This aggravates early fire detection, as it is difficult for the fire
phenomenon to reach the fire detector. An office room with normal ceiling height
has a simple room geometry.
Page 41
Project engineering
41
Building Technologies 007004_k_en_--
Fire Safety & Security Products 16.04.2009
Deceptive phenomena
Deceptive phenomena can deceive a fire detector and bring about a false alarm.
Depending on the fire detector in question, the deceptive phenomena may be e.g.
vapor, cigarette smoke, dust, dry ice in discotheques, exhaust fumes, aerosols
occurring during welding or heat sources such as radiant heaters or hot engines.
In a small hotel room with a rather low ceiling where vapor from the bathroom may
penetrate the room, or in operating facilities where a lot of dust is generated, many
deceptive phenomena must be taken into consideration. In a clean room where
electronic modules are fabricated the risk of deceptive phenomena is rather low.
Risk of fire
In production facilities where highly combustible materials such as flammable
liquids, cotton, paper etc. are processed and where electrical machines are
operated, the fire risk is very high. Minor overheating or sparks may cause a fire. In
a storehouse where steel is stored and where no electrical installation is provided
with the exception of lighting, the fire risk is very low.
Critical fire size
When a waste paper basket in a metal-processing facility catches fire, the
consequential damage is usually rather low. Here we are talking about a critical,
medium fire size that can still be tolerated. The situation is completely different in
pharmaceutical production facilities where even the lowest smoke concentration
may impair the process and where combustible materials are processed. Even the
smallest fire must be detected immediately. In this case, we speak of a small
admissible critical fire size.

High Suppression (8):
To cover applications with permanent, optical deceptive phenomena (dry ice in
discotheques, welding), this parameter set only reacts when a temperature rise of
approx. 8 K is detected in addition to the optical signal. Due to the combination of
optical and thermal signals, it is better suited than a pure heat detector. This
parameter set is also suited for applications that can otherwise only be covered
with special detectors.
Suppression (5):
Thanks to its very robust behavior, the 'Suppression' parameter set is particularly
suited for rooms where deceptive phenomena such as cigarette smoke or exhaust
fumes can be expected. It reacts in a very robust way to the deceptive
phenomenon vapor.
High Compensation (7):
This parameter set reacts in the same way as the 'Robust' parameter set; however,
the compensation range is twice as large. This parameter set is thus especially
suited for rooms in which a lot of dust and other deposits can be expected during
longer periods.
Robust (2):
The priority of the 'Robust' parameter set is to a robust response. The sensitivity is
the same as with the 'Suppression' parameter set; however, deceptive phenomena
are not explicitly analyzed and suppressed. It is thus particularly suited for us in
rooms where deceptive phenomena such as cigarette smoke or dust can be
expected. The 'Robust (2)' parameter set is suitable for higher rooms in
comparison to the 'Suppression (5)' parameter set.
Insensitive (0):
This parameter set is only available with the FDOOT2419-9 (ES <13) in collective
operation. Regarding visible aerosols the priority is on robust response. The
response behavior regarding open fires is sensitive and fast.
Balanced (4):
The 'Balanced' parameter set reveals a balanced response behavior regarding
reaction to fires and robustness to deceptive phenomena. It reacts faster with open
fires. It reacts slower with vapor, cigarette smoke or smoldering fires.

Sensitive (0):
This parameter set is only available with the FDOOT241-8 in MS8 operation. It has
been specially developed for the migration of ionization detectors to MS8 control
panels.
Regarding sensitivity and response time, the FDOOT2418 with the 'Sensitive'
parameter set reacts in a similar way to an MS8 ionization detector. The difference
in the response behavior of an optical and an ionization detector must be taken into
account.
When the detector is migrated to an FDnet detector line the parameter setting
should be changed to 'Fast Response'.
Fast Response (6):
This parameter set reacts in a fast and highly sensitive manner. It is thus especially
suited for rooms without deceptive phenomena, where the priority is on detecting
the fire as early as possible.
High Sensitive Fast (9):
This parameter set is suited for applications requiring very high sensitivity levels. It
reveals a significantly higher optical and thermal sensitivity than 'Fast Response'.
This parameter set is also suited for applications that can otherwise only be
covered with special detectors.

4.3.3 Neural fire detector FDOOT241-x (sensor mode 2, 'Smoke
detector')
This mode should be selected when fast temperature changes may occur which
are not caused by fire (e.g. radiant heaters, hot engines). In this sensor mode the
detector only reacts optically; this is comparable with a wide-spectrum smoke
detector. Thanks to a second optical sensor, however, it reveals a balanced
response behavior in relation to the different types of fire.
Robust (2):
This parameter set reacts to aerosols in a similar way as the neural fire detector
FDOOT241 in sensor mode 0 with the 'Robust' parameter set, without taking into
account the temperature.
Universal (1):
With 'Universal' the sensitivity and response time to aerosols are between 'Robust'
and 'Sensitive'.

With regard to aerosols, this parameter set reacts in a way that is comparable to
'Fast Response' in sensor mode 0 without temperature influence.

Upon commissioning of the fire detection system, the optimum parameter set must
be selected based on the existing risk and the ambient conditions.
If the fire detectors are operated on the FDnet (addressed), the fire detectors are
automatically set to the basic setting for the country in question when the control
panel is started up for the first time. Individual adaptation is made using the
commissioning tool of the corresponding control panel.
If the fire detectors are operated in collective or MS8 operation, the detectors
operate with their default setting on first commissioning. In this operating mode,
individual adaptation of the detector behavior is performed using the detector
exchanger and tester FDUD292.

When the detector is exposed to icing or moisture condensation (e.g. in cooling
rooms, attics, loading ramps) the detector heating unit FDBH291 is installed in the
base. The detector heating unit increases the detector temperature by
approximately 2 °C over the ambient temperature and thus avoids moisture
condensation on the detector.
To ensure IP protection, the base is always mounted together with the base

6 Commissioning
Commissioning on FDnet
The control panel is used to commission the detectors. The exact procedure is
described in the control panel documentation.
Commissioning on collective or MS8 detector line
The commissioning of the collective detector line is performed on the control panel.
The exact procedure is described in the control panel documentation.
After commissioning the detector line, the parameter sets can be set with the
detector exchanger and tester FDUD292.
Changing over from collective to FDnet
When changing from a collective detector line with FD20 detectors to an FDnet
detector line, the following must be taken into account:
z There is no need to exchange the detector base FDB201 by a detector base
FDB221.
z It is not necessary to replace the sounder base FDSB292, either. On an FDnet
detector line the sounder base FDSB292 behaves in the same way as the
sounder base FDSB291 with product version ES ≥30.
z When a detector is removed from an FDnet detector line and that detector is
located on a collective detector base (FDB201 or FDSB292), the
communication between the control panel and the next detector is interrupted.
In this case, alarming by the subsequent detectors is no longer possible. A fault
is indicated on the control panel.
Changing over from FDnet to collective
When changing from an FDnet detector line with FD20 detectors on a collective
line, or when new detectors are used on a collective detector line for the first time,
new, collective detector bases are mandatory!
WARNING
Removal of the devices cannot be recognized when the wrong detector bases
are used.
Fire may spread unhindered.
z Only detector bases FDB201 and FDB201-AA as well as sounder bases
FDSB292 must be operated on a collective detector line.
Changeover is normally performed automatically. With some detectors, a
temporary fault or alarm may occur during changeover. For details, see Document
008331.

7 Maintenance / repair
7.1 Status polling with the detector exchanger and tester
All detectors have an interface to the detector exchanger and tester. With this
interface, proximity data exchange is possible between the detector and the
detector exchanger and tester FDUD29x. Depending on the authorization level of
the user and the control panel type, the following actions can be performed:
z Device test (Go / No Go or detailed by status polling)
z Activation of a test alarm
z Reading out the identification number, customer text and measure text
z Localization and parameter setting of the detector (parameter setting not in
FDnet mode)
z Switching off the detector
z Resetting the control panel
For detailed information, please refer to the operating instructions of the detector
exchanger and tester (see documents 007227 and 009718).
7.2 Performance check
Through the self-test, the detectors are automatically subjected to an electrical
performance check. Regular performance checks are nevertheless required on the
detectors. This may be done with the detector exchanger and tester, test gas or by
the hot air fan.
Recommendation:
z Subject all detectors to an annual visual check. Detectors that are heavily
soiled or mechanically damaged must be replaced.
z All detectors should be replaced after 6 to 8 years of service, regardless of the
ambient conditions.

7.3 Testing detectors
Depending on the detector, testing may be performed with one or more of the
following accessories:
z Detector exchanger and tester FDUD29x (recommended)
z Test gas
‒ REF 8-S (recommended)
‒ REF 8
z Hot air fan
The following table shows which detectors may be tested with which test aids.

FDOOT221 X X X
FDO2x1 X X –

Depending on the detector, the following must be taken into account:
Detector in
test mode
To be considered
FDOOT z The FDOOT with ES < 13 reveals the same optical and thermal
sensitivity level in all parameter sets.
z From ES 13, the detector reacts in correspondence with the
parameter set in test mode. This means when the neural fire detector
is operated as a heat detector (sensor mode 1), it must be thermally
checked as well.
FDO z The detector reacts optically with medium sensitivity (2 %/m).
FDT z The detector reacts when a temperature of 60 °C is reached or at a
temperature increase of 22 K/min.
When the detector is in alarm condition, the internal alarm indicator flashes
brightly every second.

Fire Safety & Security Products 16.04.2009
7.3.1 Testing detectors with detector exchanger and tester
Testing detectors on a collective or addressed (FDnet, MS8) line is easiest with the
detector exchanger and tester FDUD29x. With the detector exchanger and tester,
the detectors can also be tested in operating mode without any problems.
A detector can also be switched to test mode with the detector exchanger and
tester. Detectors on a collective line or on an MS8 line automatically revert to
normal operating mode after 60 seconds in this case.
For detailed information, please refer to the operating instructions of the detector
exchanger and tester (documents 007227 and 009718).
7.3.2 Testing detectors without detector exchanger and tester
The fire detectors are highly resistant to deceptive phenomena. Optical fire
detectors thus recognize the immediate occurrence of smoke, as typically occurs
when testing with test gas, as a deceptive phenomenon and do not trigger an
alarm. This is desirable in normal operation; however, it does make testing with test
gas problematical.
To enable detector testing with test gas or with a hot air fan, the detector must be
switched to test mode. Testing with test gas or the hot air fan differs with
addressed and collective detector lines.
Addressed detector lines (FDnet)
On addressed detector lines, the detector or detector zones can be switched to test
mode on the control panel. Testing with test gas is then possible without problems.
Addressed detector lines (MS8)
Detectors on an MS8 line cannot be set to test mode from the control panel. Unlike
with the collective detector line, the detector is not allowed to be removed briefly
from the detector line and reinserted, otherwise all subsequent detectors will be
disconnected. Testing without a detector exchanger and tester is difficult,
specifically with smoke detectors.
Collective detector lines
Detectors on a collective line are automatically switched to test mode for 3 minutes
during startup and reset. A detector that has been newly inserted (or that has been
briefly removed from the detector line and re-inserted) is thus automatically in test
mode during the first 3 minutes.
To trigger a detector with test gas, normally 2 … 4 gas discharges at intervals of
approx. 2 seconds are required. When the detector is in test mode, activation
takes place after approximately 10 seconds.
