What are Fusible Link (or Fusible Belt) Temperature Ratings? In the simplest terms, these belts enable you for connecting a fire door opening to your main system. This will permit the firefighters easier usage of fight any fire, because they know where to quickly choose the fire with the quickest possible access. The belts also allow them to check on the temperature and to ensure that it is safe for individuals to be in the region, ahead of the fire could warm up and for smoke to fill the building.

They are specifically made for fire doors, but may also be combined with other doors such as for instance garage doors. A steel bar insulated with a polyethylene layer that's tightly fitted between two sheets of cold rolled steel is what these items are made from. The inner surface of the belt is covered in a temperature resistant paint, so once installed, the belt offers the temperature resistant seal needed to prevent heat transfer. The outer surface is made to be easily removed for cleaning, but the inner surface could be left unfastened for many years, with no visible signs of wear.

How can they work? The specific design of the Fusible Link Fire Door Opener consists of two strips of steel, one across the top of the fire door opening and another over the bottom. Each strip is attached to a steel fitting, which forms the inner the main Fusible Link Temperature Rating. Once secured, the fitting is pushed through the opening and the bars pass within the insulation, ensuring that the temperature inside the entranceway is kept at a satisfactory level. This enables the fire door to be opened quickly when the fire alarm is triggered, without risking the lives of individuals in the building.

Do they work? Although the actual performance of the Fusible Link Fire Door Opener is largely untested, it's widely regarded as a superior quality and reliable fire door product. It's been successfully utilized by large building companies to secure fire doors in high-rise buildings. An individual unit can handle the temperature rise experienced with a fire door at full open. At half open, it is still in a position to adequately maintain an appropriate temperature. Which means that a company is not needed to bother about the temperature outside their fire door being exceeded, since the interior is likely to be just fine.

Can it stop fires? No, it cannot, however it could prevent thermal transfer from the exterior to the inside of the fire door. If there clearly was an immediate transfer of heat from the fire to the steel door, it would cause significant harm to the fire retardant lining, preventing it from burning. However, this will only occur in cases when the fire door was opened directly - as an example, if the door was kicked open accidentally or intentionally. Even then, however, the likelihood of the material retaining heat because of an unintended opening is unlikely.
