OUTDOOR SOUND REPELLER.
The BS-20L Acoustic bird repeller is the ideal device for protecting outdoor environments from pest birds. Designed with advanced technology, this device offers an effective solution to repel unwanted birds, such as Starlings, Pigeons, Seagulls, Sparrows, Blackbirds, Crows, Magpies, Jays, and Woodpeckers, without disturbing pets.
ACCESSORIES
The BS-20L Bird Sound Repeller is part of a complete system designed to ensure active protection tailored to every situation. With accessories, the Sound Repeller becomes not just a protection device, but a complete and reliable solution to keep your outdoor spaces safe, in any situation and at any time.
Main Features:
Installation of the BS-20L is quick and easy, requiring no specialized technicians. The device is designed for outdoor use and is weather-resistant thanks to the included protection. For optimal effectiveness, we recommend placing the repeller as close as possible to the area infested by birds, paying attention to their flight paths and feeding habits. It is essential to clear the area by removing any nests before installation, as the attraction of the nest is very strong.

Advantages:
The BS-20L Garden 1 can be powered via the provided mains adapter (220/12V) or via a 12V external battery (not included), offering flexibility of use even in areas without power outlets. With an internal power of 30W (expandable to 60W with an optional external horn), the repeller can cover an area up to 1 hectare (10,000 m²), effectively protecting gardens, vegetable plots, orchards, balconies, roofs, and other private areas.

Benefits:
The real innovation of this combo lies in the integration of the MT-102 programmable external timer. This intuitive device allows you to precisely set the on and off times of the repeller, with the possibility of creating up to 18 daily or weekly ON/OFF programs. This functionality is essential for optimizing the repeller’s effectiveness, concentrating its action during the hours of peak pest bird activity and silencing it during rest hours, respecting the peace of the neighborhood. Scheduled programming also helps prevent birds from getting used to the sounds, making the deterrence more effective in the long run.
POWER TYPE – PACKAGE CONTENTS
Via mains adapter (220/12v included), allows you to connect the device to any electrical outlet in the house.
Power via 12 Volt external battery. The package includes a cable with clamps to connect the device to any 12V external battery. (not included)

Buying Guide
The BS-20L is a powerful acoustic repeller with audible sound emissions. Before purchasing, consider the noise impact on the area to be protected. Will it be possible to use the repeller at high volume for short periods? Before installation, it is essential to have removed any nests in the area to be protected. For pests, the attraction of the nest is always greater than any situation of imminent danger. This device requires active management to optimize results over time, by varying sounds and positioning. For an informed purchase and effective use, we strongly recommend contacting our company for personalized advice on your specific situation.
Operating Modes
Manual
In this mode, you have the freedom to choose a specific call from the list of available calls, ranging from C1 to C10. Once the desired call is selected, the bird repeller will start playing only that track, using the times set via the menu. These times, which include the Operating Time (TF) and Pause Time (TP), can be adjusted to ensure optimal device operation.
Automatic
Offers greater convenience. In this mode, the repeller is preset with a series of programs, identified from P1 to P9, which automatically configure the device with the right times based on our experience accumulated over time. By choosing one of the preset programs, you can activate the repeller without having to manually adjust the operating and pause times. The only operation required in this mode is any volume adjustment, which can be increased from 12 to 14 to ensure effective deterrence of pest birds
Custom List
This mode offers the possibility to create a custom call list, consisting of 2 to 5 tracks, which will be played in sequence. However, unlike automatic mode, you have complete control over the playback times of each call, which can be manually adjusted via the device menu. This allows you to maximize the customization of the repeller, adapting it to your specific pest bird removal needs.
Operating Mode
Daytime Operation
This mode activates the sound repeller during the day and automatically deactivates at sunset. Ideal for protecting environments during daylight hours.
Continuous Operation
This mode keeps the sound repeller active continuously for the entire 24-hour duration. Ideal for situations where constant protection is needed, day and night.
Nighttime Operation
In this mode, the sound repeller is active during the night and automatically turns off at first light. Great for protecting environments during nighttime hours.
