Sliding Fire Door - Is signage required?

A sliding fire door can be a danger to the public when closing. As a result, the Building Code of Australia ("BCA") sets out the Deemed-to-Satisfy ("DtS") requirements that state;

C3.6 Sliding fire doors

  1. If a doorway in a fire wall is fitted with a sliding fire door which is open when the building is in use—
    1. it must be held open with an electromagnetic device, which when de-activated in accordance with (b), allows the door to be fully closed in not less than 20 seconds and not more than 30 seconds after release; and
    2. in the event of power failure to the door — the door must fail safe in the closed position in accordance with (i); and
    3. an audible warning device must be located near the doorway and a red flashing warning light of adequate intensity on each side of the doorway must be activated in accordance with (b); and
    4. signs must be installed on each side of the doorway located directly over the opening stating—

      WARNING — SLIDING FIRE DOOR

      in capital letters not less than 50 mm high in a colour contrasting with the background.

    1. The electromagnetic device must be de-activated and the warning system activated by heat or smoke detectors, as appropriate, installed in accordance with AS/NZS 1905.1 and the relevant provisions of AS 1670.1.
    2. Where any other required suitable fire alarm system, including a sprinkler system complying with Specification E1.5, is installed in the building, activation in either fire compartment separated by the fire wall must also de-activate the electromagnetic device and activate the warning system.

In simple terms, a sliding fire door requires the following;

  • an audible warning device located near the doorway; and
  • a red flashing warning light of adequate intensity on each side of the doorway; and
  • signs must be installed on each side of the doorway located directly over the opening.

The details of the sign state the sign must be in capital letters not less than 50mm high in a colour contrasting with the background.
