Holyoake Curtain-type fire dampers are designed to maintain theintegrity of the fire resistance of a wall, or floor, in which a hole hasbeen formed to permit the passage of air, ducted or otherwise, toenable an air distribution system to function. The arrangement ofinterlocking blades mounted in a guide channel frame, minimizesspace requirements and facilitates ease of installation in ductwork.Fire Rating:All Holyoake Series IBD units carry up to a 4 HOUR rating toAS 1530.4 as determined by the following testing Authority.For the purposes of the Australian and New Zealand Building Code they have an FRL/FRR of – / 240 / – .

BRANZ Assessment Report Certificate No.1 IBD Damper mounted in a concrete wall, or floor. (Certified for 240 minute fire rating).

BRANZ Fire Test Certificate No. FTC 392 IBD Damper mounted in a plasterboard wall. (Certified for 30 or 60 minute fire rating). (Certificates are available upon request).

Standard Construction

Frame: 110 mm x 1.2 mm galvanised steel, roll formed guide channel.

Blades: 70 mm x 1.0 mm galvanised steel, roll formed inter-locking profile.

Springs: Blade End: stainless steel. Retraction: stainless steel. Note: Horizontal dampers with a duct ‘B’ dimension of less than 180 mm have all blades fitted with end springs only. Above 180 mm constant force springs only are fitted. All vertical dampers have the bottom blade only fitted with end springs.

Fusible Links: ‘Safe Test’ Test latch Model IBD-TL fitted as standard, complete with 71º C Fusible Link. See page 318H for more details. (Other ratings available on request). Please contact your local Holyoake branch.

Mounting: Vertical or horizontal, but in all cases the blades must be horizontal.

Alternate Electro-Thermal Resettable LinkActivation: This device can be activated by smoke detectors of

compatible design, (Supply and fit by others). By definition, a fire damper provides an effective

barrier to the passage of fire and products of combustion, but when its operation is initiated by the detection of smoke, or other products of combustion it may then be termed “smoke damper”.

The difference between a fire damper and a smoke damper is not a physical one, but is in the method of initiating the operation. (AS 1682.1-1990).

Mounting Sleeves: Series IBD fire dampers must be installed in sleeves

(refer to Pages 313H - 317H). These sleeve assemblies are available, please consult the sales office.

Stainless Steel: Construction in stainless steel is available for both

IBD and mounting sleeves.

The following installation method and diagrams (shown on the next page) are presented as the method by which Holyoake fire dampers must be installed.

It draws upon SMACNA fire, smoke and radiation damper installation guide for HVAC systems, third edition, 1986, and is intended to meet the requirements of Australian Standard 1682, Part 2, 1990.

(I) The casing shall completely penetrate the fire barrier and be retained:

(a) on both sides by means of mounting flanges in such a manner that it can expand in a fire without distorting the blades in a closed position; or

(b) on the accessible side by means of one mounting flange only, which can be fixed to the fire damper and to the fire barrier through oversized holes and penny washers. Fixings should be finger tight (to allow movement for thermal expansion), but locked, i.e. with double nut (lock nut).

Mounting flanges 5, 6, 7 shall be butted against the face of the fire barrier and fixed to the fire damper casing. The width of the angle section of the flange shall be not less than twice the clearance between the fire damper body and the penetration.

(II) The fire damper shall be installed so that the airflow2 does not impede its closure, and air velocities3 do not exceed the damper’s limit (10 m/s).

(III) The method of attachment of ductwork to the fire damper must be such that any deformation, or collapse of the ductwork in a fire, does not dislodge the fire damper, or affect its performance. This is best achieved by the use of breakaway joints which will allow damaged ductwork to fall away. e.g. Slip Joints, Proprietary Duct Flange Systems, etc.

(IV) Clearance between sleeve and penetration should be packed with compressible, non-combustable4 materials and generally be such that the hole size may be no less than overall sleeve size + 1% + 10 mm, both width and height. However, in no case should total clearance be less than the tested prototype (12 x 2 = 24), or exceed 50% of the flange face width.

(V) Access doors, or removable pressed panels, must be provided for duct entry, to test and reset release mechanisms and for inspection.

(VI) When installed and closed, the blade and pivots must be fully contained within the penetrated element and within the casing (AS 1682.2 - 1990).

(VII) Fire dampers may not be used as control dampers. i.e. They must be installed fully open.

(VIII) All Holyoake IBD type fire dampers must be sleeve mounted.5,6,7

See details on following pages.

(IX) Series IBD vertical (wall) mounted fire dampers must not be installed either with blades vertical (on end), with the blade stack below the opening, or horizontally.

(X) Ensure damper is square and free from racking, that there are no obstructions in the centre track, and that it is installed in accordance with the “this way up” arrow on every damper, both vertical and horizontal.

(XI) For Special Applications and Installation Methods, please contact your local Holyoake Branch.

Notes

1 AS 1682.1 - 1990 requires the casing to be no less than 1.6 mm in thickness.

Australian Standards Association allow that the combination of casing and

sleeve in this case satisfies this requirement. In keeping with SMACNA

recommendations, minimum sleeve thickness is 0.45mm which augments

the roll-formed section to provide a total of 1.6 mm for the smallest duct

size, and greater for larger sizes. Holyoake sleeves are a minimum thickness

of 0.55 mm.

2 Air flow may be from either direction for Holyoake Series IBD.

3 While damper size influences acceptable velocities (i.e. the larger the

damper the lower the velocity), Holyoake Industries suggests a maximum of

10 m/s on vertical gravity dampers. If velocities are expected to exceed this,

it is suggested that spring closure (type H) dampers be specified, even for

vertical mounting. Pressure differential across the closed damper should

not exceed 750 Pa.

4 Material capable of resisting high temperatures, fusing at not less than

1000ºC, such as high temperature mineral wool, may be accepted for this

purpose. Prototypes were tested with a High Temperature Loose Wool.

5 SMACNA requires the damper and retaining flanges to be secured to the

sleeve, with 6 mm bolts and nuts, 12 mm welds, 4.7 mm steel rivets, or

No. 10 steel screws. (Optional fixing screws can be provided).

6 Retaining flanges must be of minimum thickness 2.5 mm for face area

> 2 m2, or 2.0 mm for face area < 2 m2 (AS 1682.1 - 1990).

They are mandatory on all four sides, but need not be welded to form a frame.

7 Materials for sleeves and retaining flanges must comply with

AS 1682.1 - 1990, which allows galvanised steel with a coating class not

less than Z275.

Typical IBD Installation

Construction: Sleeves are corner lapped and spot-welded, then attached to the damper frame on all four sides, to form a rigid assembly.

All damper sleeves come with raw edges.

Optional ‘S’ cleats on all edges (Typical Breakaway Joint).

Optional 25, or 35 mm Breakaway flange on all edges. Do NOT use bolts, or ‘no bolt corner clips’ for Fire Damper Breakaway Joints, (Optional PVC cleats are available). (Typical Breakaway Joint – refer to Section K Accessories).

Type ‘B’ damper sleeves are fitted with a duct bridging piece.

An extended damper sleeve is available for wall depths 291 – 690 mm, (specify length required when ordering). Supplied only as part of a complete unit.

Casing sleeve may only be extended 150 mm from the face of the wall on each side, if slip joint or ‘S’ cleat is used; or 80 mm each side if ‘Breakaway’ flange is fitted.

Safe and Simple Testing Method. Test and Reset in minutes. AS 1851 - 2012 (Section 13) requires that you annually test Fire

Dampers. To ensure the Life and Property saving function for which they are

designed, all fire dampers should be drop tested after installation. All IBD dampers are fitted with ‘Safe Test’ Test Latch links.

Each Holyoake Series IBD Fire Damper is mechanically tested before it is allowed to leave the factory. In the event of damage occurring during transit, on site, or during installation, rendering any fire damper ineffective, failure to function will reveal any warping, track obstruction, or spring failure that may have occurred. This will require rectification, cleaning and removal of the obstacle, prior to retesting and handover.

The Holyoake ‘Safe Test’ IBD-TL Test Latch, is a latching device with a specially made fusible link, which, when the latch is released, swings clear and allows the curtain to close as if the link had parted under the influence of flame. After testing, the curtain can be re-stacked and the same link clipped back into the latch, where it is again ready to be released in the event of a fire.

To Operate IBD Dampers1. Remove the duct access door (refer to Section K accessories section of this manual).2. Using this access, reach in and remove the locking pin from the nearest latch.3. Check that the locking pin is still in place on the other latch, so that the fusible link is retained by it, when released.4. Check that the track is clear of any obstruction and keep hands clear.5. Lift the latch lever, and the curtain will rapidly close.6. Reload the curtain and swing the fusible link back into place in the latch.7. Replace the locking pin in the latch.8. Replace the duct access door.

To Operate IBD Dampers below minimum heights shown.1. Remove the duct access door (refer to Section K accessories section of this manual).2. Remove locking pin from both sides.3. Check that the track is clear of any obstruction and keep hands clear.4. Support the blade pack, lift both latch levers and remove fusible link.5. Release the blade pack and the curtain will rapidly close.6. Reload the curtain and support the blade pack, whilst replacing the fusible link locating pins into both latches.7. Replace both locking pins.8. Replace the duct access door.

Area Factor (From Table)

Notes1. Static Pressure and Conversion Velocities are correct for 1.2 kg/m3 air density.

2. Ratings are based on dampers installed in accordance with details in this catalogue, with ductwork upstream and downstream.

For pressure drop through an open IBD-A-V, or IBD-A-H fire damper use the

following procedure:

1. Find the Area Factor from the above table – enter duct height and width.

2. Determine Conversion Velocity (CV) by multiplying Area Factor by flow in

m3/s (CV = Area Factor x m3/s).

3. Enter pressure drop chart with Area Factor and establish intersection

with Conversion Velocity (CV) line just determined. Read pressure drop

on left hand side of the chart.

Note: Interpolations while not precise, are adequate for most calculations.

EXAMPLE:

Find the pressure drop across a 900 wide x 1504 high model IBD-A-V fire

damper, passing 11 m3/s.

1. From the table using interpolation, the Area Factor is 0.9.

2. CV = 11 x 0.9 = 10.

3. From pressure drop chart, pressure drop is 9 Pa.

(All dimensions include 6 mm clearance total between outside of damper frame and inside of duct).

Use the table and chart to determine the pressure drop through

HFS – R– 146 Fire / Smoke Dampers.

1. Determine area factor for damper by entering the area factor table with

duct width and height.

2. Find conversion velocity (CV) by multiplying area factor for selected size

damper by flow rate in m3/s. CV = Area Factor x m3/s.

3. Enter pressure drop chart with area factor and proceed up to the

appropriate conversion velocity (CV) line.

Read the pressure drop (Pa) on the left hand side of the chart.

EXAMPLE:

Find the pressure drop across a 350 wide x 814 high model HFS-R-146

Fire/Smoke Damper handling 1.3 m3/s.

1. From the table the area factor is 5.25.

2. CV = 1.3 x 5.25 = 6.825.

3. From pressure drop chart, Pressure Drop is 12Pa.

(Note: Interpolations while not precise, are adequate for most calculations).

1. Static Pressure and Conversion Velocities are correct for 1.2 kg/m3 air density.

2. Pressure drop data is for dampers tested with ductwork on both the up and downstream sides.These values need to be suitably increased where dampers

are mounted with ductwork on one side only, or when mounted onto plenum walls. (Refer to SMACNA, or ASHRAE System Design Guides).

3. Data is for the specific sizes listed in the Area Factor table. For other sizes use the next size down and make a proportional adjustment based on the

approximate increase in free area.

The Holyoake Series LR (Low Radiation) Fire Dampers are designedto impede the spread of fire and heat within building compartments, whilst maintaining the walls integrity. The low leakage insulated damper blade assembly with blade tip sealing ring, forms a solid barrier against flame, smoke and hot gases. Complying with AS/NZS 1668.1 - 1998 the LR Fire Damper is certified for a 4 hour rating in a masonry wall and a 2 hour rating in a plasterboard wall.

4 Hour FRL/FRR and Radiation Protection to AS 1530 part 4.The Holyoake LR Fire Smoke damper has been designed to providepremium protection for occupants and building structures in theevent of a fire. The innovative heat radiation blocking damper blade, will snap closed within seconds upon the air temperature reaching 71̊ C, providing rapid temperature response. Furnace testing to AS 1530.4 - 1997 has proven that the damper will stop the passage of fire and smoke through a fire rated wall for at least 4 hours.

The LR Damper integrates both a fire, smoke and control damper intoone easy to install, maintain and test unit. It is supplied complete with external low radiation sleeve and mounting flanges. Fire protection is provided by a fusible link and damper blade that seals the duct shut in the event of a fire. The damper blade is designed to reduce the transfer of heat radiationthrough the firewall, providing induct heat radiation control, while theouter solid insulating sleeve ensures minimal conduction of heat intothe wall cavity.

The unique Series LR damper design ensures that the damper blade always stays within the confines of the wall and provides a cost effective solution.
