Fire Rated Rolling Steel Door

What is the difference between a Rolling Door and a Fire Rated Rolling Steel Door? Local codes throughout the US and Canada many times require certain products and building materials to be Fire Rated, Rolling Doors are no exception. But what makes a Rolling Door fire Rated?

Fire Rated Rolling Steel Door

A fire Rated Rolling Steel Door is one that has the ability to self close in case of a Fire. The intention of the Rolling Steel door is to prevent a fire from spreading from one room to another. The rating on the door will have to match or supersede the rating of the wall. For example, if your wall has to be rated for 90 Min. Your Rolling doors should be rated for 90 min. at the minimum. Usually most Door are rated up to 3 Hrs and they are enough to comply with local codes. 

Every Rolling Steel Fire Door has to come with fusible links to self close the door.

Fire Rated Rolling Steel Door can be made Push up operation, Chain operated and motor operated. Either operation will still require fusible links and the chain or motor system will have to interact with the fusible link system. A standard Roll up door chain hoist will not work with the fire Door link system. In addition many local codes now are requiring that the fire door system is linked to the central alarm of the building to close the door. The Fire Door Release system is a bridge between the door and the central alarm. The fusible link connects the door and the fire alarm release box and the opposite end connects to the central alarm electrically via low voltage wiring. Once the alarm goes off the box separates the fusible link and the door closes.

The doors are connected to the central alarm via the door release device and can be triggered by the smoke detector or fire alarm. As a safety they also include fusible links to drop in case the detector or alarm fail. 

According to NFPA 80 (National Fire Protection Association) All and every Fire Rated Doors should be Tested annually to ensure optimal working conditions.

The requirements apply to all fire doors even if the doors are not in use and remain close all the time.Always have a trained technician inspect your fire doors.
