The ESP CCTV/B is a combined category D, C, B tested protector (to BS EN 61643) suitable for coaxial CCTV cables with BNC connectors (ESP CCTV/B) or twisted pair CCTV lines (ESP CCTV/T) on systems with either an earthed or an isolated screen.
Not suitable for use on broadcast, satellite or cable TV systems. For use at boundaries up to LPZ 0 to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.
Features & Benefits
- Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between all lines – Full Mode protection.
- Full Mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment.
- 100 MHz bandwidth prevents the degradation of high-frequency signals.
- Low in-line resistance to minimize unnecessary reductions in signal strength and maximises signalling distance.
- Very low reflection coefficient/VSWR ensure that the protector doesn’t disrupt system operations.
- Suitable for either earthed or isolated screen systems.
- Sturdy, conductive ABS housing for two-way shielding – preventing emissions & providing signals with immunity from external interference.
- Built-in DIN rail foot for easy installation on a top hat DIN rail.
- ESP CCTV/T has colour-coded terminals for a quick and easy installation check – grey for the dirty (line) end and green for the clean end.
- Integral earthing plate for enhanced connection to earth via CME kit.
- ESP CCTV/B has Network Rail Approval PA05/02510. NRS PADS reference 086/023410.
Application
Use these protectors on the video cable to outdoor CCTV cameras and central control and monitoring equipment.
Installation
Connect in series with the CCTV cable in a convenient place close to the equipment being protected. For outdoor CCTV cameras, protectors should be mounted in the junction box or a separate enclosure close to the camera. Protect central control and monitoring equipment inside the building by installing protectors on all incoming or outgoing lines, either a) near where they enter or leave the building or b) close to the equipment being protected (or actually within its control panel).
