 FAQ

1. Is this beacon easy to install? Do I need special tools or training?
Answer:
The DX-RB21 uses a standard 4-bolt installation pattern (430 mm diameter) and supports both AC and DC power inputs, making it compatible with most existing lighthouse or tower setups. No special tools are required, and we provide a detailed installation manual. For critical applications, remote technical support is available.

2. What is the delivery time after I place an order? Can you ship by sea or air?
Answer:
Standard lead time is 15–25 working days depending on quantity and customization (e.g., communication modules, color). We support both sea freight and air shipping, and can prepare export packaging to meet any international logistics requirements.

3. If the main light fails, will the beacon still work?
Answer:
Yes. The DX-RB21 is equipped with a physically isolated standby LED light that automatically activates in case of main light failure, ensuring uninterrupted operation even during critical periods.

4. Do I need internet or power at the site to monitor this beacon remotely?
Answer:
No fixed internet is needed. The beacon supports multiple remote communication options such as Beidou SMS, NB-IoT, and 4G — suitable for remote coastal or inland sites. It also accepts both AC and DC power, and optional solar integration is available upon request.

5. Is this beacon suitable for harsh weather, like heavy rain or snow?
Answer:
Absolutely. The DX-RB21 is designed for harsh marine environments. With IP65 ingress protection, corrosion-resistant housing, and an operational temperature range from -35°C to +70°C, it performs reliably in coastal storms, winter snow, and high-humidity zones.
