Fire Resistive Cable

This is commonly known as a circuit integrity ci cable and is 2 hour fire rated.

Fire resistive cable.

Vitalink armored features benefits. Thermosetting insulated armoured fire resistant cables of rated voltage 600 1000 v having low emission of smoke and corrosive gases when affected by fire. Specification for 300 500 v fire resistant screened cables having low emission of smoke and corrosive gases when affected by fire multicore and multipair cables. Ulc listed fire resistant cable circuit integrity rating cir cable fhjrc there are two issues here.

Fire resistant vs flame retardant cables. Fire resistive cables are required per nfpa 70 articles 517 695 700 708 and 760 as well as nfpa 72 nfpa 101 nfpa 130 and nfpa 502 lifeline power cables. The definition of a fire resistive or fire rated cable is a cable that will continue to operate in the presence of a fire. Vitalink is available in the us and canada.

Low smokes cables have a sheath designed to limit the amount of smoke and toxic halogen gases given off during fire situations. They have passed rigorous ul fire resistive testing maintaining a constant signal connection for two hours at 1850 f. For use as ci cable installation follows the nec and local code. Rhw 2 or rw90 two hour horizontal vertical fire resistive cables in xw breathsaver phenolic conduit ul 2196 certified fire resistive cable for survivability in a fire.

In addition to the dual rated ci cic cables vitalink now includes the industry s only armored and ethernet cables approved to ul 2196. Category standard 60 when tested in accordance with bs en 50200 method of test for resistance to fire of unprotected small cables for use in emergency circuits. An important distinction exists between fire resistant cables and flame retardant cables even though both of them are subjected to various fire performance tests in order to earn their respective classification. Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames.

Mineral insulated mi cable has provided this added protection for decades. In brief flame retardant cables are designed to resist the spread of fire into a new area. First a concern was brought to ul s attention that when fire resistive cables were installed in conduit with a zinc coating the circuit integrity was compromised by a reaction of the zinc with the copper conductors lowering. Bs 7629 1 300 500v fire resistant electric cables with non corrosive gases and low emission of smoke when affected by fire.

A flame resistant cable in this manner would let the circuit stay in operation allowing power to be transferred through it while this would not be the case with a flame retardant cable. Refer to r27557 fire resistive cable ul vitalink brand type fplr ci st1 cmr ci ls cl3r ci st1 for use in system no. Refer to installation instructions for hardware certifications. A fire resistant cable will continue to function in the event of a fire and is also identified as a circuit integrity cable a flame retardant cable on the other hand will not propagate or convey a fire.
