General information
Product description / intended use
The Techem radio frequency smoke detector 2 is used to recognise fires
early and for local acoustic alerting in the private area and in the housing
industry. – It is not suitable for applications above and beyond this.
The radio frequency smoke detector 2 operates using a tested, per-
manently integrated long-term lithium battery. – It can be muted by
pressing the user key.
Techem radio frequency smoke detector 2 – operating instructions20

The high-quality smoke detector (in the following referred to as SD) meets
the latest technical requirements. It warns you of smouldering fires and
fires with smoke development in good time, thus providing a considerable
gain in safety. – This warning function is very important as the sense of
smell is inactive when you sleep. In order to ensure that this function is
maintained, always ensure that any smoke arising in the event of fire
can reach the smoke detectors unhindered. – Therefore you must not
change the installation locations under any circumstances whatsoever!
For your own safety switch off fans and/or ventilation systems that cause
powerful flows of air, because it is possible that any smoke that develops
will not reach the smoke detector in good time or even not at all.
!Under certain conditions, the radio frequency smoke detector is
not suitable for warning people with a hearing impairment. – In this
case, please refer to your landlord or property administration.
Target group
These operating instructions are intended for flat occupants in whose
flat the Techem radio frequency smoke detector 2 is installed.
Safety instructions
• The SD is supplied with a permanently installed battery with suffi-
cient capacity for the full period of use. – Changing the battery is
not necessary and also non-permissible.
• You are not allowed to open the SD, to submerge it in water (danger
of short-circuits), to destroy it or to dispose of it in normal household
waste.
Techem radio frequency smoke detector 2 – operating instructions 21

How do I use these operating instructions?
These operating instructions are part of Techem radio frequency smoke
detector 2. – Please read the document carefully and keep it during the
entire operating life of the device. Should you move, please pass the
instructions on to the next tenant.
How does the smoke detector (SD) work?
Normal operation
Under normal operating conditions, the smoke detector need not be
operated:
User key Red LED
No operation necessary Is not illuminated
Alerting
If fire smoke develops in the ambient air, the device alerts with a loud
alarm signal:
Signal tone Red LED
Triggers a loud warning tone
(1 second on, 1 second off)
Flashes every 2 seconds
Deactivation
To switch the alarm off for 15 minutes, also in case of false or spurious
alarms, press the user key until the alarm signal is silent and the short
signal tone sounds:
Techem radio frequency smoke detector 2 – operating instructions22

User key Red LED
Press the user key until the loud
warning tone is silenced
Continues to flash every
2 seconds
!During the 15 minute deactivation period, the smoke detector
does not recognise any smoke and therefore does not trigger
any alarms.
After expiry of the deactivation, the smoke detector automatically returns
to standard operation mode.
Spurious alarms
Spurious alarms often have the following causes:
• Dust due to construction work or cleaning work,
• Sawing and grinding work,
• Steam,
• Cooking vapours,
• Temperature fluctuation (= condensation of humidity),
• Welding and separation work,
• Soldering and other high-temperature processes.
!In order to avoid spurious alarms and/or soiling the smoke detec-
tors, please observe the information in the section ”What to do
when carrying out renovation work?”
Techem radio frequency smoke detector 2 – operating instructions 23

How can I test the smoke detector?
The smoke detector fundamentally checks itself and its environment. –
However, we further recommend that you check the device yourself
at least once a year.
Extra SD servicing is not required.
Checking smoke detectors
Check the functionality of the smoke detector by pressing the user key
until you can hear the signal tone:
User key Signal tone Red LED
Press the user key until the
test alarm rings (1 second
on, 1 second off)
Test alarm with
reduced volume
Flashes every
2 seconds
!Never use a naked flame or other smoke to test the smoke de-
tector.
If no signal tone rings when the user key is pressed, the SD is faulty. – In
this case, please refer as fast as possible to the
Techem Hotline: [phone]
(6 cents / call from German landlines, max. 42 cents / minute from
German mobile phones).
When checking, please also check
• whether the casing is damaged.
• whether fire smoke can reach the smoke detectors unhindered.
Techem radio frequency smoke detector 2 – operating instructions24

This can be hindered, for example, by the later installation of room
partitions or very high cupboards / shelves. Ensure the minimum
clearance to walls, furnishings and fittings and so forth is at least
60 cm (in very confined spaces, e.g. in hallways the Techem techni-
cian can alter the required minimum clearance setting in the radio
frequency smoke detector when installing the device). The mini-
mum distance to objects (normally = 60 cm) comes from standards
requirements (= 50 cm) + measuring tolerance (= 10 cm).
• whether the SD is fully covered or partially covered or taped.
• whether the individual rooms are used differently. Minimum instal-
lation requirement: Install smoke detectors in bedrooms including
children‘s bedrooms as well as in hallways and rooms that serve
as escape routes.
• whether smoke detectors are very dusty or, for example, are heavily
soiled by cobwebs. The smoke inlets (grey grating) must be free.
• whether fluorescent tubes, fireplaces, stoves, ventilators, air-con-
ditioning and/or ventilation devices have been installed later in the
vicinity of the smoke detectors.
In case of variances, please refer as fast as possible to the
Techem Hotline: [phone]
(6 cents / call from German landlines, max. 42 cents / minute from
German mobile phones).
Techem radio frequency smoke detector 2 – operating instructions 25

Special case: SD with deactivated environmental monitoring
If in extremely rare cases
(e.g. in extremely cramped
hallways) the environmen-
tal monitoring function of
the radio frequency smoke
detector had to be deactiva-
ted completely by Techem
during installation, this will
be stated clearly on a sticker
(“Jährliche Sichtprüfung” =
“Yearly visual inspection”)
on the user key.
!In that case, the mandatory yearly check must be carried out
manually – as described on pages 24 and 25.
What should I do when renovating?
!You may neither mask the smoke detector nor cover it. Moreover,
you may neither paint over the SD nor subject it to soiling due to
work which gives off large quantities of dust.
Techem radio frequency smoke detector 2 – operating instructions26

Before you commence renovation work, you must disassemble the
SD:
1 For this purpose, turn the SD casing anti-clockwise manually.
2 Then remove it downwards from the assembly plate.
3 Mark the SD on the back with the room designation so that you can
re-install it correctly after renovation.
After renovation, you must re-install the SD again at the same place
in the same room:
4 For this purpose, compare the series number (8-digit device no. and
2-digit test mark) on the assembly plate label and on the back of the SD
(e.g.: 2122 2413 KJ).

5 Place the device on the assembly plate with a slight anti-clockwise
turn and then turn it clockwise without using too much force until
it engages.
After reassembly, the device returns automatically to normal operation
mode. – Check the functionality of the smoke detector by pressing the
user key until you can hear the test alarm signal.
!The smoke detector may be disassembled for a maximum of
2 weeks. After completion of the renovation work, restore the
functionality of the SDs as fast as possible.
If they are disassembled for longer, servicing work from Techem
is necessary and may be subject to charges.
What should I do if the smoke detector’s
environmental monitoring is activated?
!If the smoke detector‘s environmental monitoring is activated,
the cause must be rectified as fast as possible.
Causes of malfunction include, for example, all kinds of items in
the vicinity of the smoke detector (e.g. lamps, openly laid electri-
cal cables, room partitions, very high cupboards / shelves). – The
minimum gap from items must be 60 cm – measured from the
outer edge of the SD. In extremely confined rooms, for example
in hallways, it is possible for the Techem technician to set a lesser
minimum clearance in the radio frequency smoke detector during
installation.
Techem radio frequency smoke detector 2 – operating instructions28

!Further causes of malfunction include painting over, masking or
covering the smoke detector.
After you have rectified the cause of malfunction, please press the
user key and move away from the SD within 10 seconds so that
the malfunction notification can be switched off at the SD.
If you are unable to rectify the cause of malfunction, please refer
as fast as possible to the
Techem Hotline: [phone]
(6 cents / call from German landlines, max. 42 cents / minute from
German mobile phones).
For safety reasons, keep the doors open to rooms with functional
smoke detectors until the cause of malfunction has been rectified.
The activation of environmental monitoring is signalled as follows:
Signal tone Red LED
2 short, quiet signal tones every
10 minutes
Flashes twice every 30 sec-
onds
How to deactivate the environmental monitoring signal tone for 3 days:
User key Signal tone Red LED
Press the user key until a
short acknowledgement tone
sounds

After deactivation for 3 days has been made three times, deactivation
is then only possible for one day at a time.
Techem radio frequency smoke detector 2 – operating instructions 29

What should I do if the smoke detector fails or is
damaged?
!In case of failure or damages to the smoke detector, the device must
be replaced as soon as possible. Please refer without delay to the
Techem Hotline: [phone]
(6 cents / call from German landlines, max. 42 cents / minute from
German mobile phones). –
Do not try to repair faulty smoke detectors. There are no exchange-
able parts (e.g. batteries). For safety reasons, keep the doors open
to rooms with functional smoke detectors until the faulty smoke
detectors are exchanged.
Failure is signalled as follows:

Techem radio frequency smoke detector 2 – operating instructions30

How should the SDs be correctly assembled?
!Fire smoke must be able to reach your smoke detector unhindered.
Please observe this especially when making structural alterations
and installations in your apartment. If somehow possible, the SDs
must be located at least 60 cm away from all items. In case of ceil-
ing-high furniture, each section of the room should be equipped
with a smoke detector.
If changing the room use (e.g. a living room becomes a bedroom),
the existing SD installation must be checked with regard to adhe-
rence to the regulations and adapted as necessary.
This is also valid if sound propagation is hindered, e.g. through large
room partitions or noise-dampening materials.
If it becomes necessary to install the smoke detector somewhere else,
please contact your landlord or your property management represen-
tative.
The smoke detectors should only be installed by a specialist. The service
technician will stipulate the installation location in accordance with
the valid regulations. Please neither disassemble nor move the smoke
detector of your own accord.
Techem radio frequency smoke detector 2 – operating instructions 31

The distance from lamps, openly laid electrical cables, room partitions,
walls, binding beam projections, ceiling girders, corners of rooms, etc.
must be at least 60 cm. – Please make sure to observe this if making
changes to your furnishings.
In case of narrow conditions, for example in the hallway, the value for
environmental monitoring can be reduced!
