  • 1. PPPSS Cobra DetectorPV Power Plant Security System Cobra Detectors are connected at the ends of plastic fiber (POF) ring.The plastic fiber cable is passed through the holes of the photovoltaic panels Aluminum frame. Anencoded light signal is transmitted through the ring. The detectors are able to detect and report anyfiber cut to a control panel. Consequently, any attempt to remove the panels will be promptly reported.The Cobra detectors are available in two versions: with bus output (for connecting to the Defendercontrol panel) or with relay output (universal). The detectors are fitted in IP56 outdoor enclosure.Main Features• Quick and easy installation: the detector is ready for use, no need for any calibration.• No special tools: the fiber cable is connected directly to detector, without connectors or terminals.• Protection 24/7: Execute maintenance activities in the vicinity of photovoltaic panels without turning off protection.• Supplied in IP56 outdoor enclosure with triple protection. Conforms to IEC 79-2, Level II.• Additional protection is guaranteed by the digital signal transmission from detector to the central unit via BUS.• Maximum security: a square wave coded signal passes through the POF.• It is impossible to reproduce the exact same signal from external sources.• Any attempt to bypass the fiber ring or vary signal transmission even for a few msec is immediately detected.Technical SpecificationsCobra Universal Detector Cobra POF Fiber CableDetector P/N PPPSS-322 Cable P/N PPPSS-181POF Ring Length Max. 200 meter Reel Length 200 meterSignal Type Encoded Fiber 525 nm Core PMMAFiber Type POF 980 – 1000 um Cladding PFLaser Class 1M Jacket PF-HDOptical Attenuation Max. 35 dBm Refractive Index (core) 1.492Optical Power Max -4 to +2 dBm Numerical Aperture 0.47 to 0.50Universal Output 1 Potential Free Relay Attenuation @ 650 nm < 200 dB / kmEnclosure Anti-Tampering 1 Potential Free Relay Core Diameter 1.0 mmPower Supply 9 to 14 VDC Cable Outer Diameter 2.2 mmPower Consumption 50 mA +/- 30% Color BlackIP Protection IP56 Operating Temperature -50 to +75 °COperating Temperature -25 to +60 °C Min.
