Lifeline 2-Hour Fire Rated Cable
Draka Lifeline cables are designed for use in critical circuits where the cable must be able to function under conditions of direct exposure to fire and water. Lifeline safeguards critical fire alarm systems and emergency circuits by providing complete cable operation to fire pumps and power panels that provide lighting and other powered functions.
Most of the electrical systems that we use today are powered by standard electrical cables. Even the systems that we depend on in times of danger and emergency are powered by standard interconnect, control or power cables. Most of these cables do not have a tolerance for high temperature or fire, which is exactly why Draka Cableteq USA introduced a cost effective means for two-hour protection against fire and water.
Unlike other protective cable, Lifeline is a flexible, non-armored cable that allows fire controls and alarm circuits to continue to function in extreme enviroments. Lifeline Cables are also designed for critical circuit applications in fire alarm systems including detection, notification, signaling line circuits and communications. Lifeline Cable provides for active surveillance and data retrieval, firefighter communications and firefighter elevators.
Ceramified Silicone Technology
The Lifeline family of cables are produced with electrical grade ceramified silicone rubber which is proven to protect the critical circuits for your emergency systems against attact by fire and water. Under the conditions of fire or extreme heat, the ceramified silicone rubber hardens into an insulating glass-like structure, which protects the conductors against fire and water which may be present during firefighting efforts.
To ensure the quality and reliability of Lifeline cables most critical component, all silicone rubber is compounded in-house at Draka Cableteq USA utilizing proprietary formulations. All Lifeline cables utilize creamified silicone technology to achieve their fire rating. The use of silicone ensures that each Lifeline cable is flexible and has equivalent or improved electrical performance over its non-fire rated counterpart. All Lifeline cables are two hour rated per UL 2196 – Standard for Tests of Fire Resistive Cables
There are three main types of Lifeline cable. Lifeline RHW, Lifeline CIC, and Lifeline CI.
-Lifeline RHW – 600 volt power cable for use in feeder or branch circuits
-Lifeline CIC – Type FPL & NPLF cable for use in Fire Alarm Systems
-Lifeline CI – Type FPLR-CI cable for use without conduit in Fire Alarm Systems
Lifeline RHW is a composite insulation system that achieves the smallest diameter and highest temperature rating of any ceramified silicone fire rated cable. Without the need for additional fire barrier tapes, Lifeline RHW is UL listed as type RHH/RHW-2 for 90°C and UL classified with a 2-hour fire rating per UL 2196 – “Standard for Tests for Fire Resistive Cables” Lifeline RHW replaces Mineral Insulated (MI) cable, concrete encasement or construction of unnecessary fire barriers as the optimum way to protect critical circuits against fire and water.
Lifeline CIC is a cost effective means of providing survivability as required by the National Fire Alarm Code (NFPA 72). Additionally, it can dramatically increase the reliability of any fire alarm system when it is exposed to fire and water. Lifeline CIC is flexible and easy to install without the need for any special tools, hardware or instructions. Another benefit of the fire rated construction is extremely low capacitance improving system performance and eliminating the need for special mid-cap cables.
All Lifeline CI cables are qualified to UL 2196 – “Standard for Tests for Fire Resistive Cables” which includes a two hour fire exposure (accepted as representing an intense, fully developed fire within a building), water exposure and several electrical tests and monitoring to assure its circuit integrity performance. All of this in a robust non-armored fire alarm cable that is flexible, easy to install and requires no special procedures to meet code requirements.
