Fire Resistive Cable System

In many circumstances the referenced systems exist in conjunction with other fire mitigation system options which are not in question.

Fire resistive cable system. For use as ci cable installation follows the nec and local code. Ulc listed fire resistant cable circuit integrity rating cir cable fhjrc there are two issues here. This is commonly known as a circuit integrity ci cable and is 2 hour fire rated. Refer to r27557 fire resistive cable ul vitalink brand type fplr ci st1 cmr ci ls cl3r ci st1 for use in system no.

Fhit 40a and fhit7 40a for use as cic cable installation follows fhit 40a fhit7 40a and comtran s installation instructions. Mineral insulated mi cable has provided this added protection for decades. X is the size of the cable in awg or kcmil y is the size of the cable in mm2. Fire resistance rated designs are used to achieve code compliant installations where the building codes require hourly rated designs.

Suspends all cable listings to ul 2196 fire resistive fire resistant and circuit integrity cables ul has recently conducted research on a wide array of current products and systems originally certified under ul 2196 tests for fire resistive cables and ulc s139 standard method of fire test for evaluation. Or 2 hr fire resistive cable for use in elec tric circuit integrity system no. 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. Ul certifies four new fire resistive cable systems.

Fire resistive cables fire resistive conductors and components shall be tested and listed as a complete system shall be designated for use in a specific fire rated system and shall. Tratos has comprehensive modern fire testing facilities on site to ensure cable integrity. Hr horizontal 1 hr vertical fire resistive cable for use in electric circuit integrity system no. The company can supply a complete range of fire resistant cables to comply with the latest standards and codes of practice covering fire detection alarm systems emergency lighting or other vital power supplies.

Suitable fire resistance rated constructions can be identified by using our. What are fire resistive or fire rated cables. Fire resistive fire resistant and circuit integrity cables are primarily installed in mixed occupancy high rise buildings tunnels bridges and other commercial infrastructures. These 2 hour fire resistance rated systems are intended to be used in applications where conductors used for transmitting system information are required to remain operational during a fire.

Refer to installation instructions for hardware certifications. See ul fire resistance directory r19359 mm yr 3ft notes.
