Pre-Installation Site Assessment and Acoustic Line of Sight
Deploying the Telenet BR-115 Ultrasonic Double Speaker Bird Repeller effectively requires a clear understanding of ultrasonic wave behavior. Ultrasonic frequencies ranging from 25,000 Hz to 65,000 Hz behave similarly to optical light: they travel in a direct line of sight and do not penetrate solid structural barriers such as brick walls, structural concrete pillars, glass partitions, or heavy curtains.
Before mounting the device, survey the facility to locate primary pest bird activity zones. Identify specific perching ledges, ceiling trusses, rafters, entry shutters, and nesting spots utilized by pigeons, crows, or bats. Position the BR-115 with both front-facing acoustic transducers aimed directly toward these target areas to maximize the dispersion of the 90 dB, 110 dB, and 130 dB sound pressure waves across the designated zone.
Mounting Location and Coverage Optimization
The compact black metal enclosure measures 4 x 8 x 4 inches (10.16 x 20.32 x 10.16 cm) and weighs approximately 850 g, facilitating straightforward placement on flat ledges, industrial shelving, elevated structural purlins, or custom brackets. Ensure the unit is securely positioned in an elevated location facing open air to prevent accidental mechanical displacement.
- Indoor Industrial & Commercial Spaces: Provides acoustic deterrence coverage up to 800 sq. ft. in unobstructed environments such as factory workshops, storehouses, logistics godowns, shopping malls, and healthcare facilities.
- Semi-Open & Outdoor Applications: Delivers effective coverage up to 600 sq. ft. across loading docks, open terraces, building balconies, residential society rooftops, and farm houses.
- Obstruction Clearance: Keep a minimum clearance zone directly in front of the dual speaker horns. Solid obstacles create acoustic shadowing, leaving dead zones where nuisance birds may continue to roost.
Electrical Integration and Power Connection
The Telenet BR-115 features a plug-and-play architecture designed for direct integration into single-phase industrial and commercial electrical infrastructure. Connect the power cable into a standard 220–240 V AC, 50 Hz electrical socket.
With a low power consumption profile of 10–15 W, the solid-state electronic unit is engineered for continuous 24/7 duty cycles. Constant operation is necessary to maintain acoustic pressure and ensure the auto-variable 25 kHz–65 kHz sweep prevents pest habituation over time. The non-lethal electronic circuitry operates cleanly without interfering with standard industrial automation equipment or electrical control panels.
