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
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.
Wherever possible disconnect products from the power supply when carrying
out commissioning, maintenance or repair work on them.
Lock volt-free areas to prevent them being switched back on again by mistake.
Label the connection terminals with external external voltage using a
'DANGER External voltage' sign.
Route mains connections to products separately and fuse them with their own,
clearly marked fuse.
Fit an easily accessible disconnecting device in accordance with IEC 60950-1
outside the installation.
Produce earthing as stated in local safety regulations.
Assembly, installation, commissioning and maintenance
If you require tools such as a ladder, these must be safe and must be intended
for the work in hand.
When starting the fire control panel ensure that unstable conditions cannot
arise.
Ensure that all points listed in the 'Testing the product operability' section below
are observed.
You may only set controls to normal function when the product operability has
been completely tested and the system has been handed over to the customer.

Safety

Building Technologies A6V10209291_f_en_--
Fire Safety & Security Products 05.02.2010
Testing the product operability
Prevent the remote transmission from triggering erroneously.
If testing building installations or activating devices from third-party companies,
you must collaborate with the people appointed.
The activation of fire control installations for test purposes must not cause
injury to anyone or damage to the building installations. The following
instructions must be observed:
‒ Use the correct potential for activation; this is generally the potential of the
building installation.
‒ Only check controls up to the interface (relay with blocking option).
‒ Make sure that only the controls to be tested are activated.
Inform people before testing the alarming control devices and allow for possible
panic responses.
Inform people about any noise or mist which may be produced.
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
Components and spare parts must comply with the technical specifications
defined by Siemens. Only use products specified or recommended by
Siemens.
Only use fuses with the specified fuse characteristics.
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.
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
correctly when used properly. Siemens disclaims all liability for damage or injuries
caused by the incorrect application of the instructions or the disregard of danger
warnings contained in the documentation. This applies in particular to the following
damage:
Personal injuries or damage to property caused by improper use and incorrect
application
Personal injuries or damage to property caused by disregarding safety
instructions in the documentation or on the product
Personal injury or damage to property caused by poor maintenance or lack of
maintenance

3.1.1 Features of fire detection functionality
As an S-LINE detector, the FDOOTC241 has the following features with regard to
its fire detection functionality:
Dynamic influence on the parameter sets
Pattern recognition
Real time interpretation of the situation
Process- and time-controlled switchover of the parameter sets
Signal processing is based on ASAtechnology (ASA = Advanced Signal Analysis).
ASAtechnology can also be characterized as second generation algorithms. Signal
processing with ASAtechnology allows for optimum adaptation of detector behavior
to the corresponding ambient conditions.
The S-LINE detectors are characterized by their unique detection reliability and
high immunity to deceptive phenomena.

Structure and function
19
Building Technologies A6V10209291_f_en_--
Fire Safety & Security Products 05.02.2010
Algorithms
In comparison to the detection algorithms (DA), the individual parameters of the
selected parameter set can be adapted with ASAtechnology. A real time
interpretation of the situation leads to a dynamic influence on the algorithm. The
real time interpretation 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 selecting the parameter set, the S-LINE detectors enable time- or
process-controlled switching over of the parameter sets (Manned/Unmanned
switchover). The time- or process-controlled switching over of parameter sets
allows the detector to be used in places where the situation changes significantly
on a regular basis (e.g. kitchens, production halls).
Parameter sets which can be loaded
The detectors have several permanently programmed parameter sets. For special
applications new, additional parameter sets can be downloaded in the field
(depending on the control panel).

3.1.2 Features of the Technical CO Alarm
Alongside its fire detection functionality, the FDOOTC241 also has a CO detection
functionality with the following features:
Static or dynamic alarm profiles
Real time interpretation of the situation
Process- and time-controlled switchover of the parameter sets for CO
Signal processing by the 'Technical CO Alarm' is undertaken regardless of CO
signal processing for the fire detection functionality with the 'Suppression CO' and
'Balanced CO' parameter sets.
The signal processing feature of the 'Technical CO Alarm' enables optimum
calculation of the CO concentration. The electro-chemical cell allows the best
possible level of accuracy to be obtained depending on the ambient conditions.
The FDOOTC241's CO detection is characterized by the ability for parameters to
be set and a relatively low cross-sensitivity to other gases, e.g. ethanol or hydrogen
(H(H2).
