General safety notes
DANGER!
Danger of electric shock! Do not touch any live com-
ponents! Electrical equipment carries a dangerous
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.
CAUTION!
Danger due to inadvertently actuating the smoke
control damper. Inadvertent actuation of the damper
blade or other parts can lead to injuries.
Make sure that the damper blade cannot be released
inadvertently.
Regular care and maintenance ensure operational read-
iness, functional reliability, and long service life of the
smoke control dampers.
The system owner is responsible for the maintenance of
the smoke control damper. The system owner is respon-
sible for creating a maintenance plan, for defining the
maintenance goals, and for the functional reliability of
the equipment.
Functional test
The functional reliability of the smoke control damper
must be tested at least every six months; this has to be
arranged by the system owner. If two consecutive tests,
one 6 months after the other, are successful, the next
test can be conducted one year later.
The functional test must be carried out in compliance
with the basic maintenance principles of the following
standards:
EN 12101-8
EN 13306
EN 15423
Depending on where dampers are installed, country-
specific regulations may apply.
Maintenance
The smoke control damper and the actuator are mainte-
nance-free with regard to wear but smoke control
dampers must still be included in the regular cleaning of
the smoke extract system.
Inspection
Smoke control dampers must be inspected before com-
missioning. After commissioning, the function has to be
tested in regular intervals. Local requirements and
building regulations must be complied with.
The inspection measures to be taken are listed in
‘Inspection, maintenance and repair measures’
.
The test of each smoke control damper must be docu-
mented and evaluated. If the requirements are not fully
met, suitable remedial action must be taken.
Repair
For safety reasons, repair work must only be carried out
by expert qualified personnel or the manufacturer. Only
original replacement parts are to be used. A functional
test is required after any repair work
sioning/functional test’ on page 30
.
Any repair must be documented.
Cleaning
All surfaces of TROX components and systems, with
the exception of electronic parts, may be wiped with a
dry or damp cloth. Do not use cleaning agents that con-
tain chlorine. All surfaces may also be cleaned with an
industrial vacuum cleaner. To avoid any scratches, a
soft brush should be used on the suction inlet. Equip-
ment for removing stubborn contamination, e.g. scrub-
bing sponges or scouring cream, may damage the sur-
faces and must not be used.
