Deadbolts are not permitted as hardware in firedoors because they negate the function of the door to be self latching. there are options, however, as some deadbolts can be removed and replaced with certain approved hardware. that said, in many cases the only way to ensure compliances is to have the door replaced and approved hardware installed.
Yes. There are strict clearance limits on fire doors and if these gaps exceed the limits then the door is not compliant and should be replaced. In some cases, however, the use of Lorient seals can bring doors up to the standard required by AS1851-2005. You should check this with your fire service provider.
The Australian standard requires that all doors the lead into a fire isolated stairwell or corrridor must have approved signage permanently fitted to the door at eye level. In addition to this, doors that form a final exit for a fire isolated stairwel or corridor must have signage on BOTH sides of the door. Illuminated exit signs are only installed above the door on the inside of the door.
Many building owners are conducting routine replacement of the old asbestos fire doors as part of their commitment to workplace health and safety. You may not necessarily have to replace the fire doors, providing they are in good condition and are still functioning as required by the Australian standards. If the doors are in disrepair, have faulty hardware or do not have the required compliance tag on the door, the only option is to have the doors replaced and have new hardware installed.
