Dormakaba, formerly Mesker Openings, presented a 1 hour seminar on the topic of fire rated door assemblies. Summary of presentation:
- Be aware of the NFPA 80 requirements, and verify that the specified manufacturers can provide the specified products. If the plans and specification call for a fire door that is larger than what is allowed by the specified manufacturers’ listings, a construction label will have to be approved by the AHJ.
- If the project has existing fire doors that will need to be modified for new hardware, alterations that are not within the allowable field preparations must be approved in advance by the listing laboratory or the doors and frames may have to be relabeled in the field.
- Clearly state in the specifications whether openings are to be fire-protection-rated (UL 10C or NFPA 252) or fire-resistance-rated (ASTM E119 or UL 263).
- Include the post-installation fire door assembly inspection in the specification to ensure that the doors, frames, and hardware are installed properly. This is an important benefit for the Owner.
