1.9. Mechanism type
Mechanism type selection must be done according to na-
tional legislation and according to building type where re
damper will be installed. In particular it must be considered
if re protection or smoke detection system need specic
control over the re damper or if periodic controls (such as
opening and closing) are required.
1.9.1. Manual / Manual with magnet
1. Manual opening lever
2. Protection box
3. Lever position when the blade is open
4. Lever position when the blade is closed
5. Magnet knob (for magnetic version)
6. Closed blade indicator
7. Open blade indicator
8. Manual closing button
Blade closing mode
Automatic closing with thermal fuse.
The control mechanism has a thermosensitive element
that automatically closes the blade when the temperature
in the duct exceeds 70°C (or 95°C for the re damper with
95°C thermal fuse).
It is possible to close the damper by pressing the indicated
button.
If the manual mechanism is equipped with electromagnet
it is possible to remotely close the re damper.
The manual command mechanism with magnet is equip-
ped with an electromagnet which, in case power is inter-
rupted (interuption magnet version) or when power is sup-
plied (input magnet version), comands the closing of the
damper.
Blade opening mode
Make sure that the damper is open before the ventilation
system start-up, otherwise there is a risk of product mal-
function.
In case of closed damper by pressing the closing button or
remotely by electromagnet (magnetic version), it is possi-
ble to manually open the re damper blade by rotating the
lever antyclockwise.
For power supply interruption electromagnet, provide
power supply and pull the magnet knob before opening
the re damper.
In case of closed damper as a result of the action of the
thermosensitive element, it is possible to manually reopen
the damper by rotating the lever counterclockwise once
the element has been replaced.
Position indication microswitches
On request, the re damper can be supplied with posi-
tion microswitches (SA/SC/S2 optional) that signal the
blade position (open or closed). Refer to Electrical con-
nections p.26 paragraph for more details.
Closing by remote control
With power supply input or interruption magnet (WH45PM
version only).
Temperature calibration of thermosensitive element for
automatic damper closing
70 °C±7 °C (Standard)
95 °C±9 °C (On request).
1.9.2. Belimo motorized version
1. Manual closing switch
2. Manual opening lever
3. Position indicator
4. Blade locking lever
Blade closing mode
Automatic closing with thermal fuse.
The control mechanism has a thermosensitive element
that automatically closes the blade when the temperature
in the duct or in the room exceeds 72°C (or 95°C for the
95°C version).
To close the damper when the motor is connected, press
the switch on the temperature sensor or cut o the power
supply.
Blade opening mode
Make sure that the damper is open before the ventilation
system start-up, otherwise there is a risk of product mal-
function.
To open the damper with the electric motor driven actua-
tor, provide power supply to the motor. Refer to the section
Electrical connections p.26 for further information.
To manually open the damper, use the handle supplied
and carefully rotate clockwise to the 90° indicator. To hold
the damper in open position operate on the lever indica-
ted in gure.

Blade closing mode
Automatic closing with thermal fuse.
The control mechanism has a thermosensitive element
that automatically closes the blade when the temperature
in the duct or in the room exceeds 72°C (or 95°C for the
95°C version).
To close the damper when the motor is connected, press
the switch on the temperature sensor or cut o the power
supply.
Blade opening mode
Make sure that the damper is open before the ventilation
system start-up, otherwise there is a risk of product mal-
function.
To open the damper with the electric motor driven actua-
tor, provide power supply to the motor. Refer to the section
Electrical connections p.26 for further information.
To manually open the damper, use the handle supplied
and carefully rotate counterclockwise to the 90 °C indica-
tor. To hold the damper in open position, rotate the screw
anticlockwise as shown in the picture.
During the manual opening of the damper, power must
not be supplied to the motor.
Position indication microswitches
The motorized versions are supplied with two microswi-
tches to show the blade's position (open or closed). Refer
to the section Electrical connections  p. 26 for further
information.
Closing by remote control
If power to the motor is cut o, the blade will close.

3. INSTALLATION
The sizes shown are in mm.
It is recommended to perform a functional test before
Installation to exclude possible damage during transport
and another test immediately after installation to exclude
accidental damage to the product and interference with
mounting components.
3.1. Intended use
The MP3 re dampers are“Devices for use in heating, venti-
lation and air conditioning (HVAC) systems at re bounda-
ries to mantain compartmentation and protect means of
escape in case of re” according to the 3.1 paragraph of EN
15650:2010 standard.
It is compulsory to install the re damper according to the
instructions indicated in the technical data sheet and ma-
nual to maintain the declared performances and, in parti-
cular, the re classes.
The double test (with the mechanism inside and outside
the re area) demonstrated that there is no preferred di-
rection for the position of the damper, both in relation to
air ow and the side with the higher probability of expo-
sure to re, as indicated in standard EN1366-2:2015 (para-
graph 6.2).
Use permitted in any civil and industrial building.
Use permitted in saline atmosphere, for example:
• maritime and port enviroments;
• sh markets;
• slaughterhouses;
• cheese makers.
3.2. Not allowed uses
• Use with installations dierent to those described in the
technical data sheet and manual;
• use as smoke control damper;
• use as shut o damper;
• use in external environments without adequate pro-
tection from atmospheric conditions;
• use in explosive environments;
• use on board of ships;
• use in cooker extraction hoods;
• use in pneumatic conveying systems of dust or corn;
• use in ventilation systems within locations subject to
chemical contamination;
• use in non inspectable enviroments;
• installation in re resistant false ceilings crossings;
• use in ventilation ducts where condensation can occur.
3.3. Positioning brackets before xing
1. Positioning brackets
3.4. Blade rotation axis positioning
The re damper can be installed with the blade axis posi-
tioned vertically or horizontally or tilted at any angle.
3.5. Installation of exible connectors in
order to balance out the ventilation
ducts expansion
ATTENTION: the following indications must be considered
binding only if legislation or local regulation where the
re dampers are installed require the use of exible con-
nectors.
Flexible connectors compensate any duct thermal expan-
sion and wall bending in case of re.
Flexible connectors are used to limit re damper stresses
due to external forces in case of re and to preserve re
resistance class.
In general it is always appropriate the use of exible con-
nectors for the followings installations:
– light walls;
– Plasterboard and rock wool or Fire Batt (Weichschott)
sealing;
– Applique xing system.
Flexible connector must be normal ammability and in
case of re the grounding bonding should disconnet to
guarantee the complete separation between re damper
and connected air duct.
When exible connectors made of conductive material
(e.g. aluminum) are used, no additional grounding bon-
ding is required.

Despite exible connector installation, the re damper
must be installed in the construction support so that its
weight does not aect damper’s installation position both
during normal operation and in case of re.
It is recommended not to compress exible connectors in
the installation phase.
Flexible connector must be at least 100mm long and in
order that possible duct thermal expansions are balanced.
Take care that the exible connector does not interfere
with opening / closing movement of the blade.

3.8. Construction supports characteristics
The European standard for re dampers foresees a preci-
se correlation between the wall/oor characteristics and
the re resistance class obtained, as well as the correlation
between wall/oor used for the test and wall/oor used for
the actual installation.
The test results obtained on a type of wall/oor are valid
also for walls/oor of the same type but with greater thick-
ness and/or density than those used in the test.
For plasterboard walls, the test results are also valid for walls
with a greater number of plasterboard layers on each side.
As a result, the indicated thickness and density characteri-
stics are to be considered as minimum values.
The wall/oor in which the re dampers are installed must
be re class certied according to the standards foreseen
for the structure.
3.8.1. Rigid walls
Can be made with aerated concrete blocks, poured con-
crete, concrete panels, perforated cell elements in concre-
te or brick in accordance with the following characteristics:
• minimum thickness 100 mm;
• minimum density 500 kg/m³.
The use of a reinforcing beam above the opening is recom-
mended for walls made from concrete blocks, bricks or in
concrete cell elements.
For walls built with perforated elements, it is also recom-
mended that the area of the opening be made from full
elements (for example aerated concrete blocks) to guaran-
tee the correct adhesion of the mortar.
