Sliding Fire Doors

To manage and resist the spread of fire within buildings, a strategy of compartmentation is utilised. This is generally achieved by using fire rated wall systems to divide up areas into manageable risk sizes. There will be situations where large openings are required in the walls.

AAFD Sliding Fire Doors have been developed for these situations. These doors are compliant with Australian Building Regulations AS 1530 Part 4, meeting the highest Fire Resistance Level specifications.

The internal Vermiculite Monolithic Refractory Core is of solid, non-laminated construction containing no asbestos or other mineral fibres.

Every AAFD Sliding Fire Door must adhere to the following criteria:

• Comply with AS 1905.1 and the applicable State Building Code of Australia.

• Have a minimum overlap of ≥100 mm around the opening when in the closed position, at both the head and vertical edges of the door set.

• In configurations involving multiple door leaves, each leaf must have an overlap of ≥100 mm with the adjacent one.

• If the doors are intended to be held open during regular operation, they must incorporate a magnetic hold-open device that can be deactivated by a compatible fire alarm system to automatically close the sliding door.

• Special preparations are needed for plasterboard partition wall systems.

When opting for an AAFD Sliding Fire Door system, it is imperative to consider the dimensions of the opening that requires coverage and the available space around the sides and above the opening. The available sliding door configurations are as follows:

• Single Leaf
• Bi-Parting
• Multiple Leaf
• Combination Multiple Leaf Bi-Parting

Sliding Fire Doors are available with the following options:

• Automated sliding door control
• Speed limiting devices for closing speed control
• Mild steel, stainless steel and plywood facings
• Personnel “Wicket” doors with one or two Access Wicket doors

Given the size, weight, and complexity of the operating systems, building owners and operators must adhere to maintenance requirements, as stipulated in AS1851, at a minimum, to ensure the effective operation of the system in emergency situations.
