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.
lWherever possible disconnect products from the power supply when carrying
out commissioning, maintenance or repair work on them.
lLock volt-free areas to prevent them being switched back on again by mistake.
lLabel the connection terminals with external external voltage using a
'DANGER External voltage' sign.
lRoute mains connections to products separately and fuse them with their own,
clearly marked fuse.
lFit an easily accessible disconnecting device in accordance with IEC 60950-1
outside the installation.
lProduce earthing as stated in local safety regulations.
Assembly, installation, commissioning and maintenance
lIf you require tools such as a ladder, these must be safe and must be intended
for the work in hand.
lWhen starting the fire control panel ensure that unstable conditions cannot
arise.
lEnsure that all points listed in the 'Testing the product operability' section below
are observed.
lYou 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
lPrevent the remote transmission from triggering erroneously.
lIf testing building installations or activating devices from third-party companies,
you must collaborate with the people appointed.
lThe 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.
lInform people before testing the alarm devices and allow for possible panic
responses.
lInform people about any noise or mist which may be produced.
lBefore 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
lComponents and spare parts must comply with the technical specifications
defined by Siemens. Only use products specified or recommended by
Siemens.
lOnly use fuses with the specified fuse characteristics.
lWrong 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.
lBatteries 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:
lPersonal injuries or damage to property caused by improper use and incorrect
application
lPersonal injuries or damage to property caused by disregarding safety
instructions in the documentation or on the product
lPersonal injury or damage to property caused by poor maintenance or lack of
maintenance

optical and one thermal sensor.
Structure and function

2
3
4
1Labyrinth 3 Optical receiver
2Optical transmitter 4 Heat sensor
The point detector has a high-quality opto-electronic measuring chamber. The
measuring chamber contains:
lOne optical transmitter
lOne optical receiver
lOne thermal sensor
The transmitter lights up the smoke particles. The scattered light then hits the
receiver (photodiode) and generates a measurable electric signal.
In addition, the heat sensor makes it possible to detect fires in cases where no
smoke has been generated.
The combination of optical and thermal sensor signals optimizes detection
reliability with the following benefits.
lEarly detection of all types of fire, whether they generate light or dark smoke, or
no smoke at all.
lThe fire detector can be operated at a lower sensitivity level, thus achieving
improved immunity against false alarms which may be caused by cold
aerosols. In the event of an open fire, the smoke sensitivity level is raised by an
increase in temperature which makes rapidly burning fires easier to detect.
The multi-sensor fire detector OH110 has two parameter sets: 'Robust' and
'Sensitive'.

3.3 Function
3.3.1 Parameter sets
The detection behavior of the detectors is influenced by the parameter sets, so that
it can be specifically adjusted to the fire phenomena and environmental conditions
to be expected in the environment to be monitored.
All parameter sets are programmed in the detectors. To select the parameter set
used, insert the point detector into a certain detector base.
The table below illustrates the dependency between the point detector's parameter
sets and the detector bases used.

HI112 'A2S' 'B'
3.3.2 Diagnosis levels
The point detector monitors most of its functions itself. In particular it monitors the
correct functioning of the microcontroller, temperature sensors, light emitter and
light receiver.
