MIRKOO Backup Alarm 110dB 12V-80V DC Waterproof Industrial Heavy-Duty Backup Reverse Warning Alarm Super Loud Beeper for Truck Van Freight Car Lorry Heavy Vehicles (Self-Grounding Metal Sheet-2PC)

These backup alarms from MIKOO contain little bolt terminals to attach one's own wiring (with ring terminals) - the negative input has continuity with the mounting tab for a chassis-ground as well. The noise they make is a lower-pitched beep tone which packs a lot of "punch" and is very attention-grabbing. The unit accepts a wide range of input voltages. The overall construction quality is superb and appears to be very heavy duty. In the package is a nice note from the manufacturer requesting to be contacted in the event anything is damaged during shipping. Overall, these will fit the bill nicely for a backup alarm on a vehicle.

The MIRKOO Backup Alarm 110dB is a heavy-duty, industrial-grade reverse warning alarm designed to provide loud, audible alerts when vehicles such as trucks, vans, freight cars, lorries, and other heavy machinery are reversing. This particular model features a 110dB sound level and is compatible with vehicles operating in the 12V to 80V DC range, making it suitable for a wide variety of commercial and industrial applications. Below is a detailed review of this product:Features:110dB Sound Level: One of the standout features of this backup alarm is its 110dB output. This high-decibel level ensures that the alarm can be heard from a considerable distance, even in noisy industrial environments, providing a clear warning to pedestrians or other vehicles when a vehicle is reversing.Wide Voltage Range: The alarm is designed to operate within a 12V to 80V DC range, making it suitable for a variety of vehicles, including trucks, vans, freight cars, and lorries, as well as construction machinery and other heavy-duty vehicles.Waterproof and Durable: The alarm is waterproof, rated to handle harsh weather conditions, and built to withstand exposure to rain, snow, or moisture. This makes it a reliable choice for outdoor use in various climates.Self-Grounding Metal Sheet: The alarm comes with a self-grounding metal sheet, which simplifies the installation process. The self-grounding feature means you do not need to separately ground the unit, making setup quicker and more efficient.Heavy-Duty Construction: The alarm is designed to be rugged and durable, able to handle the wear and tear of industrial environments. It’s made to withstand vibrations, shocks, and extreme weather conditions, making it an ideal option for vehicles operating in tough conditions.2-Piece Set: The product comes in a 2-piece set, allowing for installation on multiple vehicles or redundancy if needed, depending on the application. This can be particularly useful if you have a fleet of vehicles or machinery.Pros:Extremely Loud: The 110dB sound is very loud and can be heard over large distances, making it highly effective in warning others of a vehicle reversing, particularly in busy, noisy environments such as construction sites or warehouses.Versatile Voltage Compatibility: The wide voltage range (12V-80V DC) ensures compatibility with a variety of vehicle types and machinery, making it a flexible solution for many different applications.Waterproof and Weather-Resistant: The waterproof feature is particularly valuable for outdoor and all-weather operations, ensuring that the alarm continues to function even in adverse weather conditions like rain or snow.Easy Installation: The self-grounding metal sheet makes the installation process much simpler and faster, as it eliminates the need for additional wiring or grounding, which can be cumbersome.Durable Construction: The heavy-duty build ensures the alarm can withstand the rigors of industrial use, including vibrations, impacts, and extreme weather.Cons:Very Loud, But May Be Too Much for Some: While the loudness (110dB) is an advantage for visibility in busy or noisy environments, it might be overkill in quieter settings or for smaller vehicles. It may also be a bit disruptive in certain environments.Installation Requires Basic Knowledge: Although the self-grounding feature simplifies installation, you still need to have basic knowledge of how to wire the alarm to your vehicle’s electrical system. For those who are not familiar with electrical components, professional installation may be needed.Bulkier Design: The alarm unit is built to be heavy-duty, but it may be bulkier compared to smaller, more compact alternatives, which could be a concern if you're looking for a discreet setup or have space limitations.Conclusion:The MIRKOO Backup Alarm 110dB is an excellent option for those needing a highly reliable and loud reverse warning alarm for large vehicles, trucks, vans, or industrial machinery. Its 110dB sound output, wide voltage compatibility, waterproof design, and self-grounding metal sheet make it a standout choice for heavy-duty applications, especially in environments where safety is paramount, and noise is a factor.While the alarm's volume is certainly a strength, it might be too loud for smaller vehicles or quieter environments. The bulkier design and installation requirements could also pose minor challenges for some users. However, for those with larger fleets or heavy-duty vehicles, this alarm provides a rugged, effective, and durable solution to improve safety while reversing.
