Mechanism type Manual 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. The damper can be closed manually as per the following instructions.

Wiring diagram for position microswitches
FCU: Closed damper contact A The fire damper’s blade is open (the air flow is allowed) B The fire damper’s blade is closed (the air flow is not allowed) 4 Normally opened (BLUE) 1 Common/neutral (BLACK) 2 Normally closed (GREY)

The fire damper is equipped with a spring for closing the blade: pay attention to the hands. Blade opening mode Make sure that the damper is open before the ventilation system start-up, otherwise there is a risk of product malfunction. In case of closed damper as a result of the action of the thermosensitive element, it is possible to manually reopen the damper once the thermosensitive element has been replaced. The fire damper can be opened manually as per the following instructions.

min. supply: 4 V AC – 1 mA max. supply: 250 V AC – 10 A

The fire damper is equipped with a spring for closing the blade: pay attention to the hands. Position indication microswitch On request, the fire damper can be supplied with position microswitch (separate accessorial) that signal the closed position of the blade. Refer to the section Electrical connections for more details.

ELECTRICAL CONNECTIONS

MAINTENANCE AND INSPECTIONS

Fire dampers and control mechanisms do not require routine maintenance. Extraordinary maintenance (repairs) and periodic inspection operations are the responsibility of the ventilation system operator. It is recommended to provide inspection hatches on both sides of the ducts connected to the fire damper. The implementation of a periodic inspection plan allows to guarantee the efficiency and functionality of the fire dampers for the fire safety of the building.
Periodic inspection and cleaning Periodic inspection shall be performed in accordance with the requirements of the law or by the building regulations or other local regulations. In the absence of specific regulations (or to their complement), in accordance with point 8.3 of the EN 1560 standard, it is recommended

to carry out the following control activities at intervals of no more than 12 months: · Check the servomotor electrical wiring for damage (where appli-
cable); · Check end-switch wiring for damage (where applicable); · Check damper cleanliness and clean where necessary; · Check the condition of blades and seals, rectify and report where
necessary; · Check the correct opening and closing of the fire damper by man-
ual operation according to the instructions in the technical manual of the fire damper; · Check the opening and closing operation of the damper controlled by the fire alarm system (if present); · Check the operation of the end switches in open and closed state, adjust and report if necessary (if it is present); · Confirm that the damper fulfils its function as part of the control system (where necessary); · Check that the damper is left in its normal operating position, which usually corresponds to the open position.
Repair For safety reasons, repair activities involving fire-fighting components must be carried out only by qualified personnel. Only original spare parts supplied by the fire damper manufacturer must be used. A functional test must be performed after each repair. At the end of the inspection, cleaning or repair operations, check that the fire damper is in the normal operating position. Keep records of all inspections, repair activities, any problems encountered and their resolution. This practice, even when not mandatory, is very useful in practice.
Disposal Disposal in case of destruction must be carried out in accordance with national legislation. For electrical and electronic parts also refer to EU Directive 2011/65.

light walls; Plasterboard and rock wool or Fire Batt (Weichschott) sealing; Applique fixing system. Flexible connector must be normal flammability and in case of fire the grounding bonding should disconnet to guarantee the complete separation between fire damper and connected air duct. When flexible connectors made of conductive material (e.g. aluminum) are used, no additional grounding bonding is required. Despite flexible connector installation, the fire damper must be installed in the construction support so that its weight does not affect damper’s installation position both during normal operation and in case of fire. It is recommended not to compress flexible 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 flexible connector does not interfere with opening / closing movement of the blade. Refer to the section Technical data for blade exposition values.
Minimum distances In accordance with Articles 7 and 13 of EN 1366-2 respect the minimum distances indicated below.
Minimum distances

INSTALLATION

The sizes shown are in mm. It is recommended to perform a functional test before Installation to exclude possible damage during transport. The fire dampers FBC must be accessible for maintenance and inspections. Blade rotation axis positioning The fire damper can be installed with the blade axis positioned vertically or horizontally or tilted at any angle.
Installation of flexible 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 fire dampers are installed require the use of flexible connectors. Flexible connectors compensate any duct thermal expansion and wall bending in case of fire. Flexible connectors are used to limit fire damper stresses due to external forces in case of fire and to preserve fire resistance class. In general it is always appropriate the use of flexible connectors for the followings installations:

Construction supports characteristics The European standard for fire dampers foresees a precise correlation between the wall/floor characteristics and the fire resistance class obtained, as well as the correlation between wall/floor used for the test and wall/floor used for the actual installation. The test results obtained on a type of wall/floor are valid also for walls/floor of the same type but with greater thickness 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 characteristics are to be considered as minimum values. The wall/floor in which the fire dampers are installed must be fire class certified according to the standards foreseen for the structure.
Rigid walls Can be made with aerated concrete blocks, poured concrete, concrete panels, perforated cell elements in concrete or brick in accordance with the following characteristics: · minimum thickness 100 mm; · minimum density 550 kg/m³. For walls built with perforated elements, it is also recommended that the area of the opening be made from full elements (for example aerated concrete blocks) to guarantee the correct adhesion of the mortar.
Light plasterboard vertical walls During testing, light plasterboard walls have been used with the following characteristics: · U-shaped horizontal metal frame (50 mm) and C-shaped vertical
frame (49 mm) made from 0,6 mm thick sheet metal; · vertical profiles placed with a maximum spacing of 1000 mm; · Filling made of rock wool;

sistance class required; · minimum density 995 kg/m³. It is generally advisable to first build the wall and then provide the opening for the fire damper.
