Legrand has extended its cable management portfolio to include a new fire protection system that conforms to stringent fire protection standards and adheres to relevant building safety regulations that apply in modern construction.
The new EZ-Path firestop system, which is designed for the ventilation of power cables and mechanical protection of data cables, reacts quickly and effectively to block the propagation of a fire as soon as it breaks out. Special materials respond to flames or heat by sealing the pathway and preventing the passage of fire, toxic smoke and heated gases. A feature of the EZ-Path system is that cables can be added or changed, without the need to remove and re-install firestopping material.
The system consists of two intumescent pads which cushion and compress the cables to prevent smoke propagation through the opening, even if the intumescent material does not expand, as in the case of cold smoke. The intumescent lining reacts immediately at the contact of the flame, or if the ambient temperature reaches 177°C. It has an expansion co-efficient of 800%, which induces a high-pressure block which penetrates the cable bundle through the entire length of the module. This ensures that the fire compartment is not compromised. Some environments need protection from changes in pressure and exposure to gas leakage. The design of this system maintains pressure differences across the wall cavity, thus limiting the dispersion of gas.
Traditional materials used to create fire barriers are often susceptible to degradation due to corrosive cleaning methods and environmental gases. Unlike these materials, which retain dust, dirt and bacterial deposits, the steel mounting plates of EZ-Path are easy to clean. The module itself is galvanised and covered with a thermo-hardening resin which offers protection from corrosion as a result of cleaning elements and other corrosive elements.
The component materials of this system also perform well in radioactive environments. The housing and intumescent lining remain stable, without becoming a radiation source after irradiation.
Any break in a wall, especially where cables pass through, can degrade the sonic barrier and create sound pollution. The cables of this system are covered with a convex shaped lining to restore the sound proofing of the opening. EZ-Path has a rate of attenuation that can reach 45 dB.
Another important feature of this system is its hygienic advantage. The lining fits exactly with the profile of the cables, leaving no space for the passage of rodents or insects that contaminate many cable support systems in buildings.
EZ-Path automatically adjusts to the number of cables installed. This system is compliant with the electrical continuity code and has complete electromagnetic compatibility. The system can accommodate cables with a diameter between 3,5 mm and 75 mm.
