Fire Door Compliance & Lock Requirements
1. Can I change my door lock?
Yes, it is possible to install a new lock on a fire door, but it must be fire-rated and compatible with the fire rating of the door’s core material. To comply with Australian Standard AS1905.1, the lock must allow the door to self-close, use a latching-type mechanism, employ a lever handle rather than a knob, and be installed at a height of 900mm–1100mm from the ground.
2. Can I install a digital lock?
Fire-rated electronic or digital locks can also be installed on fire doors, provided they match the fire rating of the door’s core material. All AS1905.1 requirements still apply, including the need for self-closing functionality, a latching-type mechanism, a lever handle, and installation at 900mm–1100mm from the floor.
3. Can I install a security lock (like a chain, deadbolt, or swing bar)?
No, additional security locks such as chains, deadbolts, or swing bars are not permitted on fire doors. These devices can prevent the door from closing and latching automatically, which is critical for containing smoke and flames during a fire. AS1905.1 specifically forbids hardware that interferes with self-latching. For example, door chains can hold a door partially open, deadbolts may block complete closure, and swing bars can prevent automatic latching or even damage the door. Only security latches that maintain the door’s fire resistance rating and allow automatic closure are allowed.
