Musical Fountain Show Control & Underwater Lighting System (DMX512/Art-Net, Grid-Powered)

Overview

The RC-FTN-600 is a complete, grid-powered show control and underwater lighting system for musical (dancing) fountains, dry-deck plaza fountains and lake floating fountains. It is built for municipalities, landscape developers, mall and resort operators, and fountain contractors who need choreographed water, light and music shows that run reliably every night with minimal on-site staff. The system integrates a REDCOAST.LTD-developed show controller, VFD pump control interfaces, SELV underwater RGBW lighting, synchronized audio and a full safety chain (wind, water level, leakage protection) into one engineered package, delivered together with a cloud management platform and mobile app so the entire fountain can be scheduled, monitored and diagnosed remotely. Because REDCOAST.LTD designs its own PCBs and firmware, the same platform scales from a small park fountain with a few dozen jets to a large waterfront show with thousands of DMX channels.

Key Features

• Frame-accurate show synchronization: water jets, RGBW lights and audio are choreographed on a shared timeline with SMPTE/MTC timecode, refreshed at up to 40 fps over DMX512-A for smooth, music-tight motion.
• Multi-universe capacity: 4 to 32 DMX universes (2,048–16,384 channels) over Art-Net/sACN on a fiber or shielded-copper backbone, controlling pumps, solenoid valves, 1D/2D/3D swing nozzles and luminaires as individually addressable devices.
• True variable water height: DMX-to-analog (0–10 V / 4–20 mA) interfaces drive VFDs from 0.75 to 90 kW, so jet height follows the music dynamically instead of simple on/off switching.
• SELV underwater lighting: 6–36 W RGBW luminaires run at safe extra-low voltage (12 V AC / 24 V DC) with IP68 sealing and 316L stainless bodies, aligned with IEC 60364-7-702 zone requirements for fountains.
• Wind-speed safety interlock: an anemometer input automatically lowers jet height or executes a controlled shutdown when wind exceeds a configurable threshold, preventing overspray onto walkways and roads.
• Full electrical protection chain: 30 mA RCD protection per lighting group, isolation transformers for underwater circuits, Type 1+2 surge protection and low-water-level pump cutoff.
• Show authoring software included: a timeline editor for water/light/audio choreography with 3D pre-visualization, plus a library of ready-made show templates.
• Cloud + app operation: calendar-based scheduling, remote start/stop, energy metering, fault alarms and run-hour maintenance reminders over 4G/5G or Ethernet.
• Custom-engineered hardware: the DMX master controller, VFD/valve interface boards, SELV LED driver boards and safety-interlock PCB are REDCOAST.LTD in-house designs, so channel counts, I/O mix and cabinet layout are tailored per project rather than forced into a fixed catalog.

Technical Architecture

The system is organized in three layers. At the top, the RC-FTN-600 show controller — an industrial edge computer with a REDCOAST.LTD-designed DMX/timecode output board — stores show files locally and plays them back autonomously, so a network outage never interrupts a scheduled performance. It outputs Art-Net/sACN over the site backbone and distributes SMPTE timecode to the audio processor, keeping water, light and sound locked to a single clock.

The middle layer consists of distributed node cabinets around the basin. Each node carries REDCOAST.LTD interface PCBs: DMX-to-analog channels that command VFDs for main and effect pumps, 24 V DC driver channels for solenoid valves and servo-driven 1D/2D/3D swing nozzles, and SELV driver boards feeding the underwater RGBW luminaires through isolation transformers. Because decoding happens close to the devices, cable runs stay short and the system remains serviceable section by section.

The third layer is supervision and safety. A dedicated safety-interlock PCB monitors the anemometer, basin water level, pump dry-run and leakage sensors, and can override the show engine independently of the playback software — reducing jet height in steps as wind rises, cutting pumps on low water, and logging every event. All telemetry (energy, run hours, VFD status, lamp group current, water level) flows to the cloud platform, where operators manage schedules and receive fault alerts on the mobile app.

Connectivity & Power

The RC-FTN-600 is a grid-powered (mains) system — musical fountains sit in urban plazas, parks, malls and waterfronts where utility power is available, and pump loads from tens to hundreds of kilowatts make grid supply the only realistic option, so no solar configuration is offered for this product. The plant-room cabinet accepts three-phase AC 380–480 V 50/60 Hz; controller and lighting sections run from protected single-phase feeds, and underwater circuits are stepped down to SELV through isolation transformers. For communications, the site backbone uses industrial Ethernet (fiber optional for long basins); the connection to the cloud platform uses wired Ethernet where the venue has a network, or an industrial 4G/5G router where it does not. Shows always run from local storage, so remote connectivity is for management, not playback.

Protection & Reliability

Control cabinets are IP55, powder-coated steel with heat management sized for -30 °C to +55 °C ambient operation; underwater luminaires and junctions are IP68 with 316L stainless housings, tempered-glass lenses and high-temperature silicone seals for continuous immersion, including chlorinated or lightly brackish water. Electrical safety follows the IEC 60364-7-702 approach for fountain zones: SELV in the basin, 30 mA RCDs, equipotential bonding points and lockable isolation for maintenance. LED luminaires are rated for 50,000-hour service life; VFD interfaces include phase-loss and overload protection; and the safety-interlock logic runs on its own PCB so a playback fault can never disable wind or water-level protection. The standard warranty orientation is 24 months on electronics with long-term spare-part support, and all boards are conformal-coated for humid poolside plant rooms.

Application Scenarios

• City plaza dry-deck fountain: flush floor nozzles and lights create an interactive daytime play area and a choreographed evening show; the wind interlock keeps spray off adjacent pedestrian zones automatically.
• Municipal park lake fountain: floating pump platforms with high-jet aerating nozzles double as water-quality aeration by day and a music show at weekends, all scheduled from the cloud calendar.
• Shopping mall / mixed-use waterfront: a signature nightly show extends visitor dwell time; operators trigger themed shows for holidays from the app without a control-room technician.
• Resort and hotel landscape: multiple smaller features run coordinated scenes from one controller, with energy metering to keep nightly operating cost visible.
• Government and cultural landmarks: large-scale synchronized shows with thousands of channels, fiber backbone and redundant playback for high-profile venues.
• Theme parks and event venues: timecode input lets the fountain follow an external show controller, joining lasers, projection and pyrotechnic-free effects on one master clock.

Case-style Examples

Central plaza dry-deck retrofit. A city upgraded a static plaza fountain into an interactive dry-deck feature: 96 flush nozzles with 2D swing mechanisms, 96 SELV RGBW ring lights and eight VFD-driven pumps on four DMX universes. The safety PCB's wind interlock and slip-risk drainage logic satisfied the municipality's public-safety review, and evening shows now run unattended on a seasonal calendar, with cleaning crews notified by app when run-hour thresholds are reached.

Lakefront musical fountain for a new district. A developer needed a signature 120 m lake show. REDCOAST.LTD engineered a 16-universe system with floating pump barges, 90 kW main-jet VFD control, fiber ring networking and a 10 kW distributed audio system. Because the interface PCBs are in-house designs, the valve-driver density per node cabinet was doubled to cut cabinet count on the barges, reducing both cost and visual clutter.

Resort courtyard multi-feature upgrade. A resort consolidated three independent legacy fountains under one RC-FTN-600 controller. Existing pumps were retained and fitted with VFD interfaces; only lighting was replaced with SELV RGBW units. Nightly synchronized scenes across all three features were delivered without re-piping, and energy use dropped roughly 30% because VFD control replaced full-speed pump operation.

Customization & Selection Guide

Size the system in four steps. (1) Channel count: small features (≤2 universes) suit gardens and courtyards; 4–8 universes cover most plaza and park fountains; 16–32 universes serve landmark lake shows. (2) Pump control: choose direct relay switching for fixed-height jets on a budget, or VFD interfaces (recommended) for music-following height control and energy savings. (3) Lighting: 6–9 W ring lights for nozzle accenting, 18–36 W floods for tall jets and wide basins; all SELV. (4) Options: water-quality monitoring and dosing (pH/ORP), fiber backbone for basins over 80 m, redundant controller for landmark venues, and timecode input for integration with external show systems. REDCOAST.LTD engineers the node cabinet I/O mix, basin layout drawings and show templates per project — including custom PCB variants where a project needs non-standard valve counts, luminaire drivers or legacy-equipment interfaces.

Deployment & After-sales

REDCOAST.LTD delivers the control system as pre-wired, factory-tested cabinets with labeled field terminals, plus basin-side junction assemblies, so on-site work is limited to mounting, cable pulls and commissioning. Typical lead time is driven by cabinet fabrication and show programming and is quoted per project scope; commissioning includes wind/level interlock testing, RCD verification and operator training. Remote diagnostics over the cloud platform cover most after-sales support; firmware updates are pushed remotely, spare boards are stocked for fast exchange, and show reprogramming (new music, seasonal themes) can be produced remotely and uploaded to the controller.

Standards & Compliance

Design and delivery are aligned with: IEC 60364-7-702 (electrical installations for fountains — SELV zones, RCD protection), IEC 60598-2-18 (submersible luminaires, IPX8), DMX512-A (ANSI E1.11) and Art-Net/sACN (ANSI E1.31) control protocols, SMPTE timecode for synchronization, CE (LVD/EMC) and RoHS directions for electronics, IP55 cabinets and IP68 underwater components per IEC 60529. Project documentation supports local electrical inspection and public-safety approval processes in any regulatory environment.
