The Telenet SS BR 135 (KT Ref: KTI10003005SSPR) is an industrial-grade ultrasonic surround sound bird deterrent designed for continuous 24/7 deployment across manufacturing plants, warehouses, loading docks, and utility substations. Engineered with solid-state electronic architecture housed in a 6.5 kg black powder-coated Mild Steel (MS) enclosure, the unit emits auto-variable frequencies between 25,000 Hz and 65,000 Hz at an acoustic pressure of 110 dB. When operational issues arise, facility engineers should consult the diagnostic procedures below to verify installation geometry, power stability, and acoustic line-of-sight.
Delayed Deterrence Effect or Persistent Avian Activity
Ultrasound pest management operates through environmental and behavioral conditioning rather than physical entrapment or lethal action. A common operational observation during initial deployment is continued avian presence. Relocating entrenched or nesting birds typically requires an uninterrupted exposure window of 20 to 30 days. Facility teams must maintain continuous 24/7 electrical supply during this initial behavioral adaptation period. Disconnecting or scheduling periodic power-offs significantly dilutes the acoustic pressure and resets the behavioral relocation timeline.
Acoustic Shadowing and Structural Obstructions
High-frequency sound waves ranging from 25 kHz to 65 kHz behave similarly to light: they travel in direct paths and reflect off hard surfaces but cannot penetrate dense physical barriers. If pest activity persists in specific zones within the 4,000 sq. ft. indoor or 3,000 sq. ft. outdoor coverage envelope, inspect the site for acoustic shadowing.
- Solid Partitioning: Ultrasound does not penetrate solid concrete walls, insulated metal partitions, heavy industrial racking, or fully enclosed machinery bays. Ensure the circular 17 in x 17 in x 6 in chassis maintains an unobstructed line-of-sight toward open air spaces and perching rafters.
- Sub-Optimal Mounting Elevation: The unit should be suspended centrally using its top mounting probe at a recommended clearance of 8 to 10 feet above finished floor level. Suspending the unit excessively high above truss lines or too low to the floor reduces horizontal multi-directional dispersion.
- Expansive Space Geometry: In long, narrow storage bays or expansive logistics hubs exceeding individual unit boundaries, deploy two units facing opposite directions to maximize acoustic reflection across hard structural surfaces.
Industrial Environmental Contamination on Transducers
In harsh manufacturing, agricultural, granary, or foundry installations, airborne particulate matter can settle over the multi-directional surround sound speaker grilles. While the solid-state architecture requires zero chemical consumables or refill cartridges, heavy dust accumulation can dampen the 110 dB sound pressure output. Periodically inspect and wipe the transducer grilles using a dry, non-abrasive cloth during routine plant maintenance audits.
Diagnostic Troubleshooting Reference
| Observed Symptom | Underlying Industrial Cause | Corrective Engineering Action |
|---|---|---|
| No repelling effect observed within the first 1 to 2 weeks | Normal behavioral relocation period in progress (requires 20 to 30 days). | Maintain continuous 24/7 plug-and-play operation without switching off the mains power. |
| Bird activity localized behind racking or bulkheads | High-frequency acoustic shadowing caused by non-permeable obstacles. | Adjust suspension position to achieve direct line-of-sight or install supplementary units facing opposite directions. |
| Intermittent pest re-infestation | Unit turned off during non-operating shifts or power interruptions. | Connect to an uninterrupted 220V AC, 50 Hz dedicated single-phase power line to prevent operational downtime. |
| Reduced deterrence range over extended service life | Transducer grilles obstructed by heavy industrial dust or particulate buildup. | Isolate power and wipe external transducer grilles clean to restore nominal 110 dB sound output. |
| Unit inactive / no power indication | Mains supply fault or damaged electrical cable connection. | Verify 220V AC, 50 Hz power input at the socket and inspect external cabling and suspension fixtures. |
