R A HIGHER LEVEL OF CONFIDENCE ™ Sentinel 6-Series Communication Line Protectors: Some face persistent system problems, despite their use of conventional communication line protectors. Others face performance expectations that allow zero tolerance for downtime. 6-Series communication line protectors are specifically engineered to satisfy these demanding applications, whether for analog, digital, or high-speed data lines. Ultimate assurance of system reliability Leading telecommunications companies employ ONEAC Sentinel communication line protectors in their installations for good reason: because Sentinel protectors provide greater assurance of PBX and key system uptime and lower service costs than conventional protectors. Eliminates harmful transients System lockups, dropped calls, mis-dials, system memory loss, “no trouble found” service calls, service outages, shortened component life — these problems result from high frequency interference. • Robust/solid state overvoltage protection: last longer in the field Sentinel protectors with ONEAC’s patented Frequency Selective Transient Voltage™ (FSTV) technology have the • Patented FSTV filter technology: allows exceptionally low let-through unique ability to discriminate between harmful and desired performance for optimum protection of electronic systems signals. This allows Sentinel protectors to prevent fast- • Convenient test points: for faster, easier line testing edged transients from entering your system, yet allow lower frequency ring voltages and lower voltage voice and • 100 A surge impulse design: provides longer lasting protection data signals to pass through unobstructed. • Models available for analog, digital, and high-speed data lines • Safety approvals: UL Listed Primary (497), UL Listed Secondary (497A), cUL Last longer on the job • 5-year warranty: the best assurance of product quality ad performance in ONEAC communication line protectors feature a more robust the industry design than others so they’re better able to withstand current and voltage surges. Which eliminates the cost and downtime • Manufactured under ISO 9001: assures consistent quality and performance. of replacement due to nuisance failures. • Free 24-hour technical support Proven to reduce service costs By removing electrical transients, ONEAC improves system reliability. Look at actual evidence — installers switching over to a protection scheme using Sentinel protectors with ONEAC Easily mountable on standard power conditioners report an over 50% reduction in total 66 blocks, Sentinel Series protectors trouble calls; 83% fewer service calls due to hardware provide more complete and longer problems; 70% fewer system resets; and 43% fewer calls in lasting protection than conventional which no trouble was found. communication line protectors.
