Manual flush bolt for wood doors

I recently observed a pair of fire-rated doors to a storage room in a school built in , with a manual flush bolt at the top of the door, no bottom flush bolt or strike to receive the bolt although the rabbet was provided in the door for a bottom corner-wrap flush bolt , a coordinator, and a closer on the active leaf.

This seems wrong on multiple levels: 1. What is the purpose of a coordinator if there is only one closer? It is obvious that the inactive leaf is intended to be normally latched. If you believe a coordinator is required for the opening, then a closer on the inactive leaf is implied.

The top flush bolt is a corner-wrap bolt, like the illustration on this Web page. Top and bottom bolts are required. I just looked at some in the Ives catalog. Here is the section: A. In such instances, the AHJ should be reasonably assured that the inactive leaf normally will be closed and latched. In this instance, when the communicating rooms are occupied by separate parties, the communicating doors are part of the guest room separation and normally would be closed. However, if the suite of rooms is occupied by a single party, the communicating doors are no longer part of the guest room separation because the suite of rooms would be considered a single guest room.

First a few important points… For health care occupancies, NFPA requires corridor doors to be self-latching, including a specific requirement for automatic flush bolts on the inactive leaves of pairs, so the NFPA 80 exception for manual flush bolts does not apply to health care corridor doors. For elevator machine rooms, refer to this blog post , which addresses the need for positive-latching hardware on these doors.

In many occupancies, manual flush bolts are not allowed in a means of egress. NFPA 80 states: 6. Your personal data will be used to support your experience throughout this website, to manage access to your account, and for other purposes described in our privacy policy.
