Brilliance Banana Peel Hi-Res component video cables are designed for higher frequency, longer distance transmissions.
Coaxial cables meet new broadcast standards
SDI coaxial cables are now specified for operation at 4.5GHz, with every reel being sweep tested for return loss and certified to the new, higher frequency.
The cables are designed to help ensure continued operation of a building's emergency warning systems for sufficient time to allow occupants to evacuate in a timely, safe and orderly fashion.
The NFPA 101 Life Safety Code, and many local building codes, mandate ongoing operation of emergency voice/alarm communications (EVAC) systems for two hours in structures where immediate evacuation is difficult or impossible, such as high-rise office buildings.
Cables designated by the NEC as Circuit Integrity are riser-rated, which means they can be installed vertically and still withstand direct contact with flame.
Cables designated as CIC may be installed in the area above a ceiling, but they must be contained within conduit.
All of Belden's New Generation Safe-T-Line cables are designed, engineered and constructed to meet applicable electrical requirements for CI, CIC and CI-PLTC as established by NEC, NFPA and UL standards and codes.
Safe-T-Line CI cables have been tested to and passed the 2-hour UL 2196 flame test without the use of conduit.
They cannot, however, be deployed in conduit and still maintain their 2-hour rating and thus are riser-rated only.
Safe-T-Line CIC cables have been tested to and passed the UL 2196 flame test while installed in EMT conduit according to the electrical circuit protective system (FHIT) 30 of the UL Fire Resistance Directory.
Therefore, CIC cables are designated for use in plenum installations, but cannot be deployed outside of conduit.
Belden also offers Safe-T-Line Circuit Integrity Power Limited Tray Cables (CI-PLTC) and higher pair/triad counts on a special order basis.
To ensure their respective 2-hour flame test compliance ratings, Belden Safe-T-Line cables feature thermoset elastomer insulation and flame-retardant, low smoke, zero halogen (LSZH) polyolefin jackets.
The cables are available in solid, stranded shielded or unshielded construction in various AWG sizes to meet a wide range of application requirements.
