3. SAFETY REQUIREMENTS
The local regulations for health and safety at work and general safety regulations to be applied.
Personal protective equipment must be worn for such types of work: re damper electrical installation, re damper
mechanical connection to the air duct system (ductwork) and any type of service or maintenance works.
Protective gloves must
be worn
Protective gloves protect
hands against abrasion,
oily environment, sharp
metal parts and contact
with hot surfaces.
Protective industrial
helmet must be worn
Industrial helmets protect
the head against impact
from objects falling from
above, by resisting and
deflecting blows to the
head.
Protective boots must
be worn
Protective boots protect
the foot from falling
objects or compression
and prevent slipping on a
slippery floor.
Incorrect use might
cause dangerous
situations.
It is important to correctly use the re damper in prescribed way only:
• Fire damper is permitted to use in exhaust or supply air systems.
• Not allowed to operate the fire damper if it do not comply with manufacturer’s installation requirements specified in
this instruction.
• Any changes or modifications of the fire damper are strictly prohibited, except for using manufacturer’s provided
replacement parts.
• Qualified staff only are allowed to replace parts or service the fire damper.

4. INSTALLATION STEPS
Before starting installation process any re damper shall be inspected for damages by responsible person!
The installation process must include the following steps:
1. Check if the blade is closing and opening without additional resistance by pressing “Push’ button several times. If
sticking occurs, lubricate rotation and sliding points as shown below using a suitable amount of grease:
2. Please consider that fire damper has exposition of the blade into the duct within a certain distance in either direction:

3. Close the blade of a fire damper. If a re damper has been installed with an open blade, this may cause incomplete
closing of the blade or even damage! Blade position can be easily controlled also after installation by referring to
marks located on the casing of locking mechanism:
• The fuse element is single-
use only and should be
replaced after activation.
• The fuse element can be
easily accessible by screwing
out PUSH button screw and
pulling out the thermal
release mechanism.
• In case the fuse element
is melted it can be simply
replaced with a new one.

Blade closed
4. Cover the main mechanism (if delivered uncovered) with plastic film or another material to protect it against clogging
with construction dust and materials.
5. Prepare installation opening in the wall in accordance with the prescriptions:
It is highly recommended to install the fire dampers in a way that completely prevents excess load on the
dampers and transfer any load from ducts or supporting constructions!
For solid walls
6. The distance between multiple fire dampers installed close to each other shall not exceed 200 mm, as well as damper
must not be installed closer than 75 mm to the walls, ceiling or other partitions, but it is recommended to leave the
access space to main mechanism at least 300 mm.

Note: for installation of a damper into a wall axle of the blade should be positioned horizontally only! Blade of a damper always has to be
placed INSIDE the supporting construction. Main mechanism can be used as a guide to find right damper’s position:
Recommended distance between supporting construction (wall or
ceiling) edge and main mechanism of the fire damper is 8 to 10 mm.
It is extremely important that the blade is positioned into the
supporting construction, if possible closer to its center.
Red duct tape can be used as a guide to identify fire damper’s blade
position.
It is important to select only appropriate fastening for fire damper supporting based on its weight, kg:
Please be advised, that after installation of the damper periodical inspections will be held in accordance with p. 4 and it is necessary to
ensure access to the main mechanism of a fire damper.

7. Fill in the gap between the casing and supporting construction with prescribed type of the filler and let the filler dry
out completely.
8. Visually check that fire damper is securely installed into the supporting construction, check if the fuse element and
levers system are undamaged and check if the blade is closing and opening properly by pressing “Push’ button
several times. The blade must be fully closed and no seizing should be observed.
9. When fire damper is fully installed and verified, make sure it is left in its normal working position with blade OPEN.
10. Please consider that all EU working safety and Fire safety standards must be observed during the installation
process.
11. End position microswitches is an additional option that can be used to identify the blades position from a distance.
For each position of the blade (OPEN / CLOSE) one end switch is needed. Meaning in total it will be two end
position switches for one fire damper. It is easy to mount end positions switches on fire dampers with plastic
actuation mechanism – only one additional plastic part must be installed. This plastic part comes as a set with the
switches.

Installation steps:
4.1. Signalling devices (switches) installation instructions for re dampers UVS-H
If fire damper is additionally completed by one or two signaling devices (microswitches) and switch cam, simple
installation of the parts is required:
Switch cam – 1 pc. Microswitch – 1 or 2 pcs.
1. Unscrew damper’s handle holding screw DIN 912,
then remove handle and cap.
2. Place switch cam to
the axis and one or
two microswitches
to the indicated
positions. Make sure
that the cam ledge
pushes the microswi-
thes’ metal plate.
3. Place
switch cam
and handle
back and
screw in
DIN 912

4. Connect microswitches to designed way. Each
microswitch has NC (normally closed), NO (nor-
mally open) and C (common) poles. Connection
scheme using signaling device:
Using an appropriate tool (e.g. pliers), GENTLY
fold the metal plate as shown:
ACTION SHOULD BE TAKEN IF THE CAM DOESN’T PUSH
