Detailed FAQ Section
How does the SPLR-3 connect to the SPL-12W spotlight?
The SPLR-3 uses a direct hardwired connection via a dedicated harness that interfaces with the SPL-12W’s control module. Each directional control (pan, tilt) is transmitted through the cable bundle without wireless lag or signal loss. The wiring kit provided ensures easy matching with the standard electrical color codes.
Because it’s hardwired, this control offers unmatched precision and timing. Simply connect power, ground, and control signals based on the included wiring schematic. For boats using multiple helm stations, SPLR-3 can be configured as the primary bridge controller while supporting auxiliary input systems if needed.
Can I use the SPLR-3 with a 24V system?
Yes. The Marinco SPLR-3 is designed for compatibility with both 12V and 24V DC marine electrical systems. This makes it ideal for a wide variety of boats—from small cruisers using 12V batteries to larger vessels running full 24V DC bus systems. Ensure that the SPL-12W spotlight is also compatible with your vessel’s power system to avoid voltage mismatch.
Always confirm your system’s voltage before installation. Using incorrect voltage can damage the spotlight or controller, void warranties, and pose safety risks.
What are the advantages of using hardwired spotlight controls?
Hardwired controls offer superior reliability, especially in critical marine applications. Unlike wireless systems, they don’t suffer from signal dropouts, battery issues, or interference. Key benefits include:
- Reliable in all weather conditions
- Ideal for fixed installation and commercial boats
- More secure and less prone to damage or loss
If you regularly operate in challenging waters, a hardwired system like SPLR-3 provides peace of mind and functional consistency.
Is the SPLR-3 waterproof and corrosion-resistant?
Absolutely. The Marinco SPLR-3 is housed in a marine-grade, weather-sealed casing that protects internal components from water intrusion, salt spray, and UV exposure. It meets IP-rated waterproofing standards, ensuring safe operation even when exposed to high humidity or direct splashes.
To further extend its lifespan, users should perform routine inspections and occasionally apply protective coatings to exposed metal terminals, especially in tropical and salty marine environments.
Can I install multiple control points for the SPL-12W spotlight?
Yes. In advanced marine setups, you can pair the SPLR-3 with other compatible Marinco spotlight accessories to enable control from multiple stations, such as the bridge and an auxiliary deck panel. This allows flexible control depending on vessel configuration and crew location during operations.
Be sure to use the appropriate switching relays and isolation modules to prevent signal conflict. For most use cases, SPLR-3 serves as the primary controller, while secondary remotes or dash controls can be added with minimal rewiring.
Conclusion
