1 Safety

1.1 General safety notes

Sharp edges, sharp corners and thin sheet metal

parts

CAUTION!

Danger of injury at sharp edges, sharp corners

and thin sheet metal parts!

Sharp edges, sharp corners and thin sheet metal

parts may cause cuts or grazes.

– Be careful when carrying out any work.

– Wear protective gloves, safety shoes and a hard

hat.

Electrical voltage

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.

1.2 Correct use

The fire damper is used as an automatic shut-off

device to prevent fire and smoke from spreading

through ducting.

The fire damper is suitable for supply air and extract

air systems.

Operation of the fire damper is allowed only in com-

pliance with installation regulations and the technical

data in this operating and installation manual.

Modifications of the fire damper and the use of

replacement parts that have not been approved by

TROX are not permitted.

Incorrect use

WARNING!

Danger due to incorrect use!

Incorrect use of the fire damper can lead to dan-

gerous situations.

Never use the fire damper

– in areas with potentially explosive atmospheres

– as a smoke extract damper

– outdoors without sufficient protection against the

effects of weather

– in atmospheres where chemical reactions,

whether planned or unplanned, may cause

damage to the fire damper or lead to corrosion

1.3 Qualified staff

WARNING!

Danger of injury due to insufficiently qualified

individuals!

Incorrect use may cause considerable injury or

damage to property.

– Only skilled qualified personnel must carry out

work.

The following degrees of qualification are required for
