General safety notes
Electrical voltage
DANGER!
Danger of electric shock! Do not touch any live
components! Electrical equipment carries a dan-
gerous electrical voltage.
– Only skilled qualified electricians are allowed
to work on the electrical system.
– Switch off the power supply before working
on any electrical equipment.
Correct use
The smoke detector is used for smoke detec-
tion in ventilation and air-conditioning systems
(AHU).
Fire dampers or smoke protection dampers
can be triggered (closed) by the smoke
detector.
The duct smoke detector can also be used to
switch off the fan in a ventilation system.
The duct smoke detector can be used in
supply and extract air systems.
In public swimming pools, the use is only per-
mitted in pure supply air ducts (without circu-
lating air).
Use in extract air ducts for kitchens or labo-
ratories must be checked on a case-by-case
basis.
Operation is only permitted in accordance with
the installation instructions and the technical
data in these installation and operating instruc-
tions.
Modifying the duct smoke detector or using
replacement parts that have not been
approved by TROX is not permitted.
Only use TROX test gas for the function test.
Incorrect use
WARNING!
Danger due to incorrect use!
Misuse of the duct smoke detector can lead to
dangerous situations.
The duct smoke detector must not be used:
– in areas with potentially explosive atmos-
pheres (EX);
– outdoors without adequate protection
against the effects of weather;
– in areas with direct sunlight
– in atmospheres where chemical reactions,
whether planned or unplanned, may cause
damage to the duct smoke detector or lead
to corrosion

Qualified staff
WARNING!
Danger of injury due to insufficiently qualified
individuals!
Incorrect use may cause considerable injury or
damage to property.
– Only specialist personnel must carry out
work.
Personnel:
Skilled qualified electrician
Trained personnel
Qualified electrician
The qualified electrician is a person who due to his
professional training, knowledge, and experience,
as well as knowledge of applicable standards and
regulations, is capable of executing work on elec-
trical equipment and is capable of autonomously
recognizing and avoiding possible hazards.
The qualified electrician is specially trained for the
work environment where he is active and is familiar
with the relevant standards and regulations.
Skilled qualified electrician
Skilled qualified electricians are individuals who
have sufficient professional or technical training,
knowledge and actual experience to enable them to
work on electrical systems, understand any poten-
tial hazards related to the work under consideration,
and recognise and avoid any risks involved.
Trained personnel
Trained personnel are individuals who have suffi-
cient professional or technical training, knowledge
and actual experience to enable them to carry out
their assigned duties, understand any potential haz-
ards related to the work under consideration, and
recognise and avoid any risks involved.
Safety signs
The following symbols and information signs can be
found on the product.
WARNING!
Danger due to illegible signage!
Over time, labels and signs can become dirty
or otherwise unrecognisable, so that hazards
cannot be recognised and necessary operating
instructions cannot be followed. There is then a
risk of injury.
– Ensure that all of the safety, warning and
operating information is clearly legible.
– Replace illegible signs or labels immediately.
Electrical voltage
Only qualified electricians are allowed to work in
areas marked as having electrical voltage.
Unauthorised persons must not open the marked
areas.
