WXHU Lindab Smoke Control Dampers Installation Guide

WXHU Lindab Smoke Control Dampers

Introduction

This mounting instruction refers to a circular smoke control damper for single compartment tested in two hours at a temperature of 600°C at a positive pressure of +500 Pa and negative pressure of -1500 Pa in installation on a duct penetrating a vertical or horizontal wall with two relay response options: type AA (Automatic Activation) and types MA (Manual Activation). Both motorized versions are suitable for combined use in smoke control and HVAC systems (e.g. reversible system).

The damper is classified as following standards:

• E600 120 (ved – hod i↔o) S 1500 C10000 AA single
• E600 120 (ved – hod i↔o) S 1500 C10000 MA single

Intended use

The damper is a part of a smoke and fire protection system and is designed to reach the following targets:

• Extract smoke for 2 hours during the fire
• Reduce temperatures during the fire
• Opens the blade and removes heat and smoke from a compartment in fire
• Closes the blade to prevent the spread of heat and smoke to a safe compartment
• Create a non-smoke layer
• Protect the property

This damper represents a part of the smoke and fi re protection project and shall be designed by a fire expert. The products used in system should not be larger than dimension Ø 630.

Transport and delivery

The delivery contains smoke control damper marked by a CE label on the outside of the product. The transport is performed by common transport means. Components that are free-loaded should be secured in such a way that any deformation and damage to the components will be eliminated. The transport vehicle must be covered to prevent dust, debris and humidity to damage the
components.
Components are delivered without an acceptance at a supplier´s as default. If an acceptance at a supplier´s is required, it is necessary to state this requirement in the order purchase contract. A buyer or his/her representative is obliged in terms of good acceptance to on site check these according to the delivery documentation. Visible defects and amount shortages are to be noticed in the transporter´s transport sheet immediately.
Storage
The goods should be stored inside and protected to prevent dust, debris and humidity to damage the goods.

Operation

All smoke dampers have an electrical actuator. They are designed to be installed indoors in a smoke evacuation and standard HVAC system. Before starting the system it is necessary to check the system for damages and that it is consistent to the fire expert design. The system can be used only in compliance with determined conditions (pressure, temperature etc.).

Applied Documents

This smoke damper has been certified together with the Lindab smoke evacuation system (see “duct and fittings” secion on this manual). The damper shall be used in the same way it was used during the tests. No manipulation or substitution of any components of the damper is possible.
Producers of the smoke damper:
MP3 S.r.l., via G. La Pira 9, 35012 Camposampiero (PD), Italy – belongs to the holding Lindab.

Declaration of performance
The damper is CE marked with the declaration of performance according to EN12101-8 as a circular smoke control damper single compartment with CPR nr. 1812-CPR-1189.

Revision and Maintenance

Following features shall be checked up during a revision of the damper at least once a year:

• All parts are to be installed according to this mounting instruction.
• The damper must not be damaged in any way, the cross-section of the casing, the motor and the covering box of the motor must not be damaged in any way.
• All connections with the smoke evacuation system are to be tightened and properly connected.
• The ducts connected to the damper must be suspended or supported in order to bear the damper’s weight too.
• There must not be any flammable bodies on the damper surface and 50 mm away from the system itself.

Before mounting

Before starting the mounting of the damper it is necessary to inspect all components to make sure that they are correct according to the project documentation and to make sure they have not been damaged during transport or storage. When handling the products on site it is important to be careful so that they don’t get damaged and their properties change. Mounting of the damper should only be done by trained professionals equipped with the correct protective equipment and tools. The mounting of the damper should always be performed according to valid documentation from the manufacturer. The damper should never be used as a supporting part of the building.
In order to achieve a good result, ensure you have:

• A well-organized and protected storage site for components and other parts that are to be assembled.
• A properly planned assembly sequence in accordance with the instructions.

Mounting

Preparations:

• Cut ducts at right angles.
• Carefully remove any burrs from cut edges. Installation is easier and the risk of damaging the gasket is reduced if there are no burrs.
• Cut away the needles created from the fold.

Assembly

• Start by inserting the turned-over edge of the damper into the duct.
• Check that the fi rst lip of the gasket is in contact with the edge of the duct all the way around and sticks straight out so that the lip is not twisted in one direction or the other.
• Push the end of the damper into the duct. Twisting the damper slightly aids insertion.
• Secure the damper in the duct using self-tapping screws Ø4,2×13.
• Fasteners should be positioned on the duct close the damper (minimum 10-15 mm) to support itself weight and to prevent damage to the gasket.
• The damper must be installed on certifi ed and CE marked smoke control system. Note that the damper is a  compontent of the system, please readand follow the mounting instruction of the whole smoke control system itself (page 6).

2-wire open-close control. The actuator is overload-proof and can thus remain energized even at the end stops. Two micro switches with fixed settings are installed in the actuator for indicating the damper end positions. The position of the damper blade can be read off on a mechanical position indicator. The crank handle supplied with the actuator allows it to be operated manually

Note

• Caution: Main power supply voltage!
• Parallel connection of several actuators is possible. Power consumption and switching thresholds must be observed!

Note

• Supply via safety isolation transformer!
• Parallel connection of several actuators is possible. Power consumption and switching thresholds must be observed!

Electric cables and system
For the Manual Activation version (MA), the electric cables and system must have at least 30 minutes of circuit integrity.

Inspection of the damper

Each damper should be inspected after installation and every 12 months. The damper is part of the SHEVS. Therefore the system must be checked as specified in its operational and maintenance according to the national requirements.

Conformity assessment by the installer
This is only a conformity assessment that the installer approves and thereafter gives to the contact from the supplier of the documents. This signature only shows that the installer received the installation manual and that he or she followed it gradually.

I hereby confirm that I received the installation manual from the supplier and followed it gradually.
