The installation shall be in accordance with the manufacturer’ s installation instructions, an assessment, test report or allowable installation variations in AS 1682.1. In addition, the installation shall comply with the following site specific requirements:
(a) The method of attachment of ductwork to the fire damper shall include breakaway joints in accordance with Appendix C so that any deformation or collapse of the ductwork in a fire does not dislodge the fire damper or adversely affect its operation or performance. Attachment between damper and riser ducts do not require breakaway joints providing that the riser shaft only contains building services,excluding gas and fuel lines, and is not used in any way for storage of materials.
NOTES:
1 See Figure C1 for typical breakaway joints.
2 Compliance with the requirements of Appendix C is intended to meet the objectives of Clause 6. 1
(a) of these installation requirements.
(b) Damper casing or mounting sleeve shall not extend beyond the face of the wall or floor by more than 150 mm on either side, except in the case where a motorized fire damper (or smoke damper) extends up to 250 mm on the motor side only.
(c) Installation shall not have any obstruction that prevents closure of the damper.
(d) Convenient access shall be provided for commissioning and maintenance (inspection,release and reset), both internally and externally.
(e) Unless stated otherwise in the manufacturer’s installation instructions, the max imum size of the opening in the structure shall not exceed damper size by more than the width of one mounting flange on the face of the structure. The minimum size of the opening in the structure shall be not less than that nominated in the manufacturer’s instructions. Where the actual penetration exceeds the maximum stated in the manufacturer’s installation instructions, or as above, options for correcting this non-compliance are either of the following:
(i) Size of opening shall be reduced while maintaining the FRL. .
(ii) Larger mounting flanges shall be installed such that the width of the flange on the face of the building element is at least twice the clearance between the building element and the damper casing. In this case, width of mounting flanges shall not exceed the maximum width that has been subject to the fire test in AS 1682.1.AS 1682.2 pdf free download.
