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, mounting, 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.

Building Technologies A6V10334410_h_en_--
Fire Safety 2015-09-29
Mounting, 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.
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 alarm 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 design and the 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 Overview
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 'FXS2055 ASD
Asyst Tool' 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.
Examples of application
Cavities such as false ceilings or false floors
Rooms with polluted air, in which the pollution has impaired the performance of
optical point detectors
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
