Technical Library > CE Marked Approved Fire & Smoke Damper Installation Manual

Introduction

Over the years there have been lots of attempts to provide generic information with regard to damper installations. These have come from the old GLC regulations, which were adopted by industry bodies and supported by test houses and trade associations. However, with the publication of BS EN 1366-2:1999 the European standard for the fire testing of dampers (no specific standard existed before) and revisions to the guidance from the UK regulators (Approved Document B - ADB) it has been difficult for manufacturers to provide such generic information.

The method of damper installation is important as it is the interface between the damper and the supporting construction. It plays a significant role on the final result of the test and thus the classification of the damper. Manufacturers products cannot be assumed to perform the same in every installation, more importantly different manufacturers products will have their own performance classification.

The classification states the performance of the fire damper, for the installation method, as a time. This indicates the suitability of the damper in that particular installation method for its Integrity (E) and if available for the specific product, the damper leakage to achieve a Smoke Classification (S). The SmokeShield and CSS ranges, both have E and ES classifications, and the FireShield has E classification, but the performance in time can vary with differing methods of installation. Therefore manufacturers must provide specific data as it represents what has been tested or assessed.

Previously assessments to meet the requirements of BS476 were most common, but these are not easy to come by with regard to the BS EN 1366-2:1999 test methods. It is important to check that your proposed installation method meets one of those described. Guidance is also available in the HVAC document DW145 that outlines the industry standard for the installation of dampers. Regulatory requirements have changed and are changing, use this document along with DW145 to make sure your design and installation meets the current requirements as fire dampers are life safety products.

Ruskin Air Management Limited is not able to approve specific installations that vary from those tested and described in this publication. You may seek assessment from bodies such as BRE/LPC or WFR who will require fully dimensioned drawings with material details for your proposed installation, together with any copies of our test reports for the product.

Our products are third party certificated, in addition to full ISO 9001:2008 quality assurance. The notified body check the products to ensure that they are still being manufactured as tested or assessed, that components are traceable back to the fire tests, assessments and product design files. The Loss Prevention Certification Board (LPCB) performs our QA and product audits.

While we have undertaken extensive testing, we continue to carry out tests to reflect industry practices. Supplement test reports are available from the actionair sales office.

Requirements and Regulations

British & European Standards

These are published standards on product definition, testing and classification, system requirements, recommendations and maintenance.

Approved Documents

These are published guides described as practical guidance to meeting the requirements of the building regulations.

Requirements.

The Building Regulations This is the law.

Certification Standards

These are standards published by certification bodies to ensure products have undergone the necessary third party testing. They are then used by a notified body as the basis to ensure that products remain as tested, and that changes are re-tested or assessed by qualified personnel. There are further documents available, which are referenced in ADB that give details to designers to allow the consideration of business risk issues from smoke and fire - i.e. financial loss and is sponsored by insurers, to help assess premiums.

 

Building Regulations

By following the instructions in the approved documents you will fulfil the requirements of the regulations. If you can prove (with evidence or calculation) that another method is satisfactory you may use this, this is called fire engineering, but must be approved by a Building Control Authority (BCA) before use.

England & Wales

The document that gives an interpretation of the rules for Fire Safety is Approved Document B (ADB). This is available as a free download from the Planning Portal website.

It recommends the use of products meeting independent certification schemes, such schemes certifying compliance with the requirements of a recognised document, which is appropriate to the purpose for which the material is to be used. In addition to life safety it mentions the protection of property, including the building itself, stating that this may require additional measures, and insurers may seek their own higher standards, before accepting the insurance risk.

There have been a considerable number of changes with regard to fire dampers. They now have their own section giving very specific guidance.

  • Paragraphs 5.46 to 5.48 Mechanical ventilation and air conditioning systems state that fire dampers protecting escape routes should respond to a smoke detector or suitable fire detection system, a fusible link alone is not acceptable and this implies that some type of actuator be used. The purpose of this is to ensure early closure to prevent passage of smoke. It also states that a damper with an ES classification may be used.
  • Paragraphs 10.11 to 10.15 Fire dampers are more specific and also require actuation for fire dampers in buildings where there are levels of sleeping risk. The note that fusible link only dampers being unsuitable to protect escape routes is repeated together with the suitability of an ES rated product. 10.15 explains the requirements for E and ES classifications, to achieve any classification fire dampers must be tested to BS1366- 2:1999. A Fire Damper has an E (Integrity) classification. A Leakage Rated Fire Damper has an E (Integrity) and an S (Reduced Leakage) classification.

SmokeShield dampers fulfil the ES requirements for escape routes and areas with sleeping risk. FireShield fulfil the E requirements and can be used in all other areas for run out ducting etc.

ADB states that dampers should be mounted within the structure that they are seeking to protect and should be installed as tested.

A statement saying that fire dampers tested only to BS476 may only be appropriate for fan off situations.

For the purposes of application, what are presently known as combination fire and smoke dampers, providing that they have an ES classification to BS EN 13501-3:2005, now termed leakage rated fire dampers, actuated via a smoke detection system will fulfil the requirements for the protection of escape routes and the protection of areas with sleeping risk. Curtain fire dampers and other dampers having an E classification to BS EN 13501- 3:2005 will fulfil the general requirements for all other applications and areas.

Scotland

These exist as technical standards (AMDs). They give very similar guidance to ADB. They already include direct references to the application of European standards. They are available as a free download from the Scottish Executive website.

Standards

Fire Damper Standards

BS EN 1366-2:2015 (Test standard)

Gives requirements for testing dampers to the standard time/ temperature curve with a requirement to close within two minutes of the start of the test. After closure a 300Pa pressure differential is applied to the damper and the damper leakage (corrected to 20°C) is recorded throughout the rest of the test. The largest size of damper to be offered for sale must be fire tested. Pass and fail criteria is included in the standard.

  • Integrity E - The damper must leak no more than 360m³/hr/m² at any point during the test.

  • Optional Integrity and Leakage ES - the damper must leak no more than 200m³/hr/m² at any point during the fire test. This also applies to the largest and smallest size of damper to be offered for sale at ambient temperatures for the ES criteria to be applicable.
  • Optional Insulation I - insulation rating not required by legislation for dampers in the UK.

BS EN 13501-3:2005 (Classification Standard)

States times and performance to enable the classification of fire dampers (E, ES and I requirements).

BS EN 15650:2010 (Product standard)

Contains the basic performance and requirements for fire dampers.

System Design & Related Standards

BS 9999:2008 code of practice for fire safety in the design, management and the use of buildings provides guidance on the ongoing management of fire safety in a building throughout the entire life cycle of the building, including guidance for designers to ensure that the overall design of a building assists and enhances the management of fire safety. It can be used as a tool for assessing existing buildings, although fundamental change in line with the guidelines might be limited or not practicable.

The standard builds on government guidance to legislative requirements, providing an advanced approach to fire safety in the design, management and use of buildings. It promotes a more flexible approach to fire safety design through use of structured risk based design where designers take account of varying human factors.

BS EN 12101-6:2005 Smoke and heat control systems. Specification for pressure differential systems gives test procedures for the systems used, as well as describing relevant and critical features of the installation and commissioning procedures needed to implement the calculated design in a building. It covers systems intended to protect means of escape such as stairwells, corridors and lobbies, as well as systems intended to provide a protected fire fighting bridgehead for the Fire Services.

Certification Standards

LPS 1162 is a typical product certification standard. It contains all the tests that the Loss Prevention Certification Board (LPCB) requires the product to undergo, before certification may be offered. It also states that to meet it, a company must have full BS EN ISO 9001 accreditation. The LPCB visit the factory at least once a year to confirm by measurement that the certificated products maintain all the tested dimensions, and confirm that the products still comply with any assessments that may have been made. Using certificated products mean less time needs to be taken checking up that products meet the required standards, as a third party is making sure that this is the case

Extended Fields of Application (Assessments)

Under BS EN 1366-2 etc specific documents are being drafted for the extended field of application for all products. It is becoming clear that assessments for small component changes and the use of units smaller than those tested are allowable. However the use of methods of installation other than that tested will lead to problems, with assessments being difficult to acquire. The reason for this is the fact that the test is passed or failed based on the leakage of the unit during the test, as well as any failure at the boundary between the damper and the supporting construction. The damper closing is just the start of the test. The laboratories are unwilling to state that a change in building in method will not affect the leakage performance. Previously, under the BS 476 ad-hoc testing, assessments were forthcoming with respect to installation, this was because the test pass or fail criteria were purely mechanical with gap gauges etc, not leakage measurement.

CE Marking & Third Party Certification.

Certain European member states, including the UK & Ireland, have until now chosen not to make CE marking mandatory for products sold within their boundaries, despite the fact that under the Construction Products.

Directive (CPD) it has been mandatory to ‘CE’ mark construction products placed on the European market. In 2011 the CPD was replaced by the Construction Products Regulation (CPR) which does not allow any member state to ‘opt out’ of mandatory CE marking. Consequently, from 1st July 2013 the CPR states that all products that fall within scope of Harmonised European Standards (hENs) will have to be CE marked.

The installation methods contained within this manual are third party tested or assessed, and certified, by our Notified Body (LPCB), as prescribed within the CPR.

The message is simple from 1st July 2013, ensure that every product specified is properly certified (CE marked) and installed correctly. It is also important to be wary or avoid products that use phrases such as designed to meet and complies with, the key word to look out for is certification.

Installation Methods

The following sections deal with the installation methods. There are dimensional drawings and a detailed description of each method. In each case the classifications are shown, together with the fire test reference. Fire test reports are available in full from the actionair sales office. They are large documents, we are not permitted to abridge them, they are available as a PDF document.

Alternative partition systems to those shown within this installation manual can be used if they have been shown by test to have at least the same fire resistance when tested to BS EN 1364-1:1999 as is required of the damper. If the partition system has been successfully tested without stone mineral wool, it does not have to be used in practice when only considering the fire performance of the complete system. The mineral wool may still be needed for other reasons e.g. acoustic performance.

The mortar used in the tests shown within this installation manual had a standard sand/cement mix in the ratio of 4:1. Alternative fire resisting refractory mortars may be used providing that they have been tested in accordance with BS EN 1366-3:2009 for the required period when installed around the damper.

The ablative batt penetration sealing systems used in the tests shown within this installation manual was 60mm thick Rockwool Ablative Coated Batt. Alternative batt penetration sealing systems may be used providing that they have been tested in accordance with BS EN 1366-3:2009 for the required period when installed around the damper.

DW145

Guide to good practice, for the installation of fire and smoke dampers. The DW145 guide is intended to highlight and clarify the important aspects of fire and smoke barrier/ damper installation, including the responsibilities of all parties involved in the overall sequence from system specification through to a compliant installation. Emphasis is placed on the need for all parties to work as a team by recognising not only their individual responsibilities, but also those of all other parties in achieving this goal.

The guidance only relates to the installation of fire dampers and leakage rated fire smoke dampers as used in ventilation systems to maintain fire compartments and/or protect means of escape from buildings and does not cover the installation of powered smoke control dampers.

The importance of installing damper arrangements that have been selected/specified by the system designer and that have been successfully fire tested by an independent body on behalf of the damper manufacturer is emphasised throughout the guide.

Communication between team members and the need for consistency in both design and approach are key factors in achieving a compliant design. The guide recommends that check lists are utilised and adapted to suit the specific requirements of an individual project. Typical check sheet are included in appendix E of the guide and we have developed check lists for inspection and handover (E3 in the guide) specifically for our dampers.

DW145 Inspection & Handover Check Sheet

The installer must complete this installation certificate when installing fire and smoke dampers. A separate certificate must be completed for each individual fire and smoke damper.

Periodic Maintenance

BS EN 15650:2010 - Ventilation for Buildings - Fire Dampers

Section 8.3 states regular testing/inspection should be undertaken to meet regulatory requirements, or at intervals not exceeding six months. A comprehensive example of the maintenance procedure is given in Annex D of the standard. Some automatic systems may allow more frequent testing (48hr or less) and this may be required by a national standard.

Approved Document B, Volume 2

Clause 10.12 states adequate means of access must be provided to allow inspection, testing and maintenance of both fie damper and its actuating mechanism.

 

BS 9999:2008 - Code of Practice for the Fire Safety in the Design, Management and Use of Buildings - Annex V

V.3.5 Smoke Control Systems

For means of escape states actuation of the system should be simulated once a week. It should be ensured that any fans and powered exhaust ventilators operate correctly, smoke dampers close (or open in some systems), natural exhaust ventilators open, automatic smoke curtains move into position, etc.

V.5 Three Monthly

In addition to the checks recommended in V.2, V.3 and V.4, the actuation of all smoke control systems should be simulated once every three months. All zones should be separately tested and it should be ensured that any fans and powered exhaust ventilators operate correctly, smoke dampers close (or open in some systems) etc.

V.7 Yearly

In addition to the checks recommended in V.2 to V.6 arrangements should be made for annual inspections and tests of the following to be carried out by competent persons, for any defects  to be logged and the necessary action taken, and for certificates of testing to be obtained.

 

BS 9999:2008 - Code of Practice for the Fire Safety in the Design, Management and Use of Buildings - Annex W

Maintenance of air conditioning  and ventilation equipment including air filters, motors, fe dampers and their controls, smoke detectors and alarms is of paramount importance both in preventing fie and in ensuring that measures taken to mitigate its consequences are effective when needed.

Arrangements should be made for all fie dampers to be tested by a competent person on completion of the installation and at regular intervals not exceeding 2 years. They are to be repaired or replaced immediately if found to be faulty. Spring operated fie dampers should be tested annually and fie dampers in dust laden and similar atmospheres should be tested much more frequently, at periods suited to the degree of pollution.

Ductwork

Ductwork to be fitted and connected to damper spigots in accordance with DW144 & DW145. Aluminium rivets should be used to act as a breakaway joint, unless fire resisting ductwork is being used where resting fixings should be used. 

Health & Safety

This process must be undertaken by competent persons. More than one person may be required to ensure the safe handling of large dampers and other materials.

Use must be made of access equipment to ensure unsafe practices are not used to approach walls or difficult access areas.

Standard site PPE should be used (minimum steel toe cap boots, hard hat) together with protective eyewear, gloves and masks, when drilling or cutting is being undertaken. The latter should also be used when handing the wall construction materials, as defined by the material suppliers. If loud equipment is being used, hearing protection should be worn.

All waste materials should be collected and disposed of as defined by the relevant supplier.

If using an automatic control system this can be achieved by running a test cycle and checking the blades (open and closed) and the status indication at the control system. 

Drywall Partition - Sleeve & Angle (S&A)

 

Damper Installation Method

  1. Measure the overall damper casing size, if Smoke shield, include the PTC shroud, but do not include the peripheral flange.
  2. Calculate the hole to cut size by adding two board thicknesses, +10mm tolerance, to the finished hole width and height.
  3. Mark out the hole on the partition and cut it out, cutting the top and bottom edges first to maintain stability.
  4. Frame out the hole with stud and track and cover this with a layer of board. Finish edges with joint filler.
  5. Rivet steel duct, (by others) to damper spigot on non access side, using steel rivets.
  6. Rivet support angle cleats supplied by actionair to duct section.
  7. Suspend the damper from the ceiling using 10mm studding drop rods.
  8. Fix 4-off angles to steel duct, non access side, using steel rivets.

Actuator Fitting (If required)

  1. The control mode/actuator should then be fitted using the instructions supplied with it.
  2. Using the supplied drilling template, drill into the ductwork and fit the Electrical Thermal Release (ETR) into the duct (as good practice, this should be towards the top of the duct).
  3. A special feature of the actionair SmokeShield modes is that they may be adjusted from pointing straight out along the duct (standard configuration) through 90° to point either up or down if required.
  4. The mode should be wired into the system using the site wiring detail, plus the details shown on the label. Note: If the mode/actuator fitting instructions are missing, please contact the actionair sales office.

Commissioning

The procedure detailed under periodic maintenance should be followed.

Horizontal in Floor Slab Sleeve & Angle (S&A)

 

Damper Installation Method

  1. Position and fix the unistrut supports to the underside of the slab, at either end using M10 fire rated fixings - leave some clearance between unistrut supports, so the damper and duct section can be lowered in easily.
  2. Fix perimeter steel angles to the underside of the slab, which support the Ablative Batts, with M10 fire rated fixings
  3. Fix section of duct to the damper spigot on the Access side, (if the actuator is located upwards).
  4. Lower the damper and duct section into and onto the supporting unistrut sections, making sure you allow sufficient space to fit the required motor / actuator, (if required).
  5. Make sure the area within the aperture and the damper casing is free from any debris and remove any dust.
  6. Where the coated Batt contacts the surrounding aperture, damper casing and flange, or where two coated Batts are in contact, use Rockwool fire pro glue as the adhesive. 
  7. Continue installation of Rockwool ablative coated BATT, until aperture is completely filled.
  8. Ablative coated batt is not intended for maintaining the load bearing capability of the floor. Suitable precautions such as adequate safety rail and signage should be adopted to raise awareness and potential accidents.
  9. The damper requires suitable support on the floor side, by others.

Rigid Wall or Floor Construction (CSS)

General

This method of installation is effectively suitable for most wall types of rigid construction, where they are of an equal or greater density to the lightweight board partition tested. Details shown are essentially for an existing dry wall partition. However this installation method may be used for masonry or block work walls or concrete floors, as long as they have a greater density than the partition shown. Also a drywall partition may be built around the damper, as long as the clearances are followed.

Damper Installation Method

  1. Measure the overall damper casing diameter. Calculate the finished square hole size by adding 10mm ± 5mm to both width and height (For drywall partitions, calculate the hole to cut size by adding two board thicknesses to the finished hole width and height).
  2. Mark out the hole on the partition and cut it out, cutting the top and bottom edges first to maintain stability.
  3. For drywall partitions, frame out the hole with stud and track and cover this with board. Finish edges with joint filler.
  4. Install the damper and fasten one Installation Flange so that the blade in it’s closed position is in the centre of the wall.
  5. Fill the 4 triangular voids between the damper and the edges of the hole with fire rated stone wool.
  6. Fit the remaining Installation Flange

Actuator Fitting (If required)

  1. The control mode/actuator should then be fitted using the instructions supplied with it.

ASFP - Association For Specialist Fire Protection

The Association was formed in 1976, and represents UK manufacturers and contractors of specialist passive fire protection products such as fire resisting and smoke control dampers, with associate members from regulatory, certification, testing and consulting bodies. The ASFP seeks to increase awareness and understanding of the nature of fire and the various forms, functions and benefits provided by passive fire protection. They are willing to make available their specialist knowledge on all aspects of fire protection and can assist specifiers and main contractors in identifying products suitable for specific requirements, both in the UK and related overseas markets. The Association encourages experimental work related to passive fire protection and promotes consideration and discussion of all issues affecting the fire protection of buildings. Major publication/coloured books are referenced in Approved Document B - Fire safety, the government guidance to Building Regulations for England & Wales. Coloured books are comprehensive documents on the use and evaluation of passive fire protection products in buildings. Many contain lists of products which have had their performance verified by third party certification. They do not cover installation.
