Janus International has successfully completed fire-door burn testing at the Underwriters Laboratories (UL) facility in Northbrook, Ill. The company’s Sure-Set fire door was awarded a 45-minute and 90-minute UL label for sheetrock and non-masonry walls, and a three-hour and four-hour UL label for masonry walls. Janus permanently affixes standard and oversize labels to the door’s bottom bar.
In addition, the Sure-Set fire door offers an optional UL “S” label for building conditions that require the minimization of smoke and draft infiltration.
The Sure-Set fire door has installer-friendly designs such as weldment approval to steel jambs, thread-cutting steel fasteners and impact-drive masonry fasteners. It also has a greatly simplified, time-saving installation and drop-testing procedure. Other features include pre-punched universal headplates and transition brackets that allow for quick and easy field changes, guide service cutouts, and pre-set barrel spacing.
Operationally, the Sure-Set door features a floor-test chain-hoist governor as the standard base model, with three fail-safe, floor-test motor options in sizes approved to 50 feet wide by 30 feet high. Fail-safe release devices are available in five models, with smoke-detector and ADA-compliant visual and audible appliance options to complete the most stringent specification requirements.
Finishes for the door include standard powder-coated guides, bottom bars and headplates, with a finish painted galvanized curtain and hood. There are five color choices for curtains and hoods, with optional powder-coat and stainless-steel finishes.
