#<strong>261</strong>Common <strong>Jamb</strong> <strong>Construction</strong> <strong>for</strong> <strong>Rolling</strong> <strong>Fire</strong> <strong>Doors</strong>:Masonry <strong>Construction</strong> - Bolted and Welded GuidesIntroduction:<strong>Rolling</strong> fire doors are tested by being mounted to a furnace which is in compliance with UnderwritersLaboratories requirements. The doors are mounted on the jambs of a masonry wall intended to replicatefield construction. The fire door guides must remain securely fastened to the jambs at the end of fire test.This DASMA Technical Data Sheet includes a representation of jamb construction and guide attachmentdetails. Guide configurations and approved jamb construction will vary with individual fire doormanufacturer's listings. Consult with individual manufacturers <strong>for</strong> specific guide details and theirapproved jamb constructions.Objectives:The objectives of preparing the set of standard details are as follows:1. To show how fire door guide assemblies are located on the jamb <strong>for</strong> face of wall mounting andbetween jamb mounting.2. To provide recommendations <strong>for</strong> rebar locations in jambs.3. To help architects, engineers and others involved with building specifications understand therelationship between the rolling steel fire door guides and the jamb/wall design.4. To help door dealers and distributors know the limitations <strong>for</strong> welding guide angles to steel jambs.5. To have the details included in applicable reference documents used by architects, engineers,specifiers and code officials.Special Notations:1. UL has approved the welded guide details ONLY AS SHOWN.2. FM does not allow guides to be welded to steel jambs.See the following pages <strong>for</strong> a list of standard jamb construction details.8/6/01 rev. 10/11 Page 1 of 18 This sheet is reviewed periodically and may be updated.
