Janus International has teamed with Underwriters Laboratories to complete an extensive program which allows the retrofit of failsafe motor operators and chain hoist governor systems to existing fire doors and shutters of most UL Labeled American and Canadian manufacturers.
These competitively priced retrofit units eliminate tension release and reset entirely from existing fire doors and shutters and feature simple, bolt-on conversion components to produce reliable, modern, floor-level-test fire protection systems.
Frequently an existing fire door may be in acceptable condition, but will not drop test satisfactorily or may require an upgrade in operation that is otherwise unavailable or not approved by the listing agency. Janus has addressed this need with two specifically-designed fire door motor operator types that provide internal release, internal drop speed governing, onboard battery backup to prevent nuisance drops, and instant floor level push-button reset. These operators may be wired directly to the fire alarm control panel or may function as a stand-alone fire alarm control panel supporting such appliances as smoke and heat detectors as well as ADA compliant notification appliances such as horns and strobes.
In addition, the Janus Chain Hoist Governor has been tested and approved for retrofit to existing doors up to 385 square feet in area. It features an all steel gear reduced, bolt-on unit that provides internal release, on-board variable rate drop speed governing and instant floor level reset
It features an all steel gear reduced, bolt-on unit that provides internal release, on-board variable rate drop speed governing and instant floor level reset. This modestly priced conversion package yields service door functionality, eliminates tension release requirements and provides simple floor-test and reset capabilities. It is also available in fail-safe configuration, allowing the same detection, notification, battery backup and FACP features of the motor operator systems.
