retrofit fire door operator guide

Retrofit fire door operators provide state-of-the-art technology for existing rolling fire doors. When retrofitted, even older doors can be tested and reset easily, and operate with the reliability and extraordinary descent control found only in the most advanced fire door systems available today. Retrofit operators are Underwriters Laboratories (UL) Classified and FM Approved for installation on most types and brands of existing rolling fire doors. They eliminate awkward and unreliable spring tension release mechanisms and replace traditional operating and governor systems. They may also be installed to replace similar type failsafe operating systems. All retrofit fire door operators feature an internal release and governor to provide automatic closing without a loss of spring tension and eliminate the need for traditional mechanical reset.
