RIKEN KEIKI RS-10/RM-5000 Multipoint Indicator Alarm Unit 52K0113903

RIKEN KEIKI RS-10/RM-5000 Multipoint Indicator Alarm Unit 52K0113903

The RIKEN KEIKI RS-10/RM-5000 (Part No. 52K0113903) is a 4-point fixed gas detection indicator and alarm assembly engineered for continuous atmospheric monitoring in marine engine rooms, cargo pump rooms, and offshore process control panels. Built around the modular 5000-04W wall-mount multi-unit chassis and integrated TAN-5000 common buzzer module, this system processes real-time combustible, toxic, and oxygen signals from remote detector heads while delivering localized visual/audible alarms and isolated relay outputs to the ship’s centralized alarm and monitoring system (AMS).

Technical Specifications: RIKEN KEIKI RS-10/RM-5000 (52K0113903)

Terminal Allocations & Field I/O Architecture

• AC Power Input Terminal Plate: Dedicated L (Line), N (Neutral), and E (Protective Earth/Frame Ground) M3 terminals rated for 100–240 VAC 50/60 Hz input, protected by an inline replaceable cartridge fuse.
• Common Alarm & Buzzer Terminals (TAN-5000 Slot): Provides dry relay contact outputs for Common First Alarm (ALM1), Common Second Alarm (ALM2), and Common Fault/Trouble (FAULT), plus external buzzer reset/acknowledge input terminals.
• Per-Channel Detector Head & I/O Terminals (Channels 1–4): Each channel slot maps independently to field terminals for:
  • 3-Wire / 4-Wire Sensor Excitation & Signal Input: +24 VDC power, 0V/GND, and mV bridge or 4–20 mA analog sensor signal input (CVVS shielded twisted/multi-core cable).
  • Individual Channel Relay Contacts: Dedicated ALM1, ALM2, and FAULT dry contacts per channel.
  • Analog Retransmission & Comms: Individual 4–20 mA DC loop output (+/-) and RS-485 A/B differential data bus terminals.

Features

1. High-Visibility 3-Color LCD Status Indication: Backlit character display and 50-segment bar graph automatically shift from green (normal) to orange (1st alarm) and red (2nd alarm), allowing instant visual triage across dimly lit engine control rooms.
2. Universal Marine AC Power Input: Integrated wide-range power supply accepts 100–240 VAC at 50/60 Hz without manual voltage tap changes, stepping down to a regulated 24 VDC internal bus.
3. Modular Hot-Swappable Card Architecture: Individual indicator modules (RM-5000 series) and the TAN-5000 buzzer module slide into guide rails with mechanical locking levers for rapid board-level replacement without disturbing field conduit.
4. Dual-Stage Programmable Alarm Logic: Supports independent ALM1 and ALM2 setpoints with configurable self-latching, auto-reset, or lock-in relay behaviors, alongside non-latching fault diagnostics for sensor wire breaks or power drops.
5. Low Power Consumption & High Density: Consumes 75% to 85% less power than legacy RIKEN KEIKI RM-570A/580 controllers while supporting up to 32 networked points via optional RS-485 Modbus communication.

Compatibility:

• Compatible Gas Detector Heads (Remote Field Transmitters):
  • Combustible Gas (Catalytic / New Ceramic / Thermal Conductivity): RIKEN KEIKI GD-A80, GD-A80N, GD-K88Ai, GD-F8A (paired with GP-5001, NC-5001, NC-5001W, or NP-5001 cards).
  • Toxic & Oxygen Gases (Electrochemical / Galvanic / Sample Draw): RIKEN KEIKI GD-70D Series, GD-A44V, OX-series (paired with EC-5002, OX-5001, RM-5003, or RM-5003T cards).
  • General 4–20 mA 2-Wire / 3-Wire Transmitters: Compatible with standard industrial 4–20 mA gas transmitters via RM-5002 / RM-5003 indicator modules.
• Legacy System Retrofit Compatibility: Can replace older RM-570A and RM-580 series multi-point panels using the RIKEN KEIKI 5000-CC conversion adapter case without re-pulling existing field sensor cables.

Frequently Asked Questions

What is the difference between RIKEN KEIKI 52K0113903 and 5000-04W?

52K0113903 is the complete factory assembly part number for the RS-10/RM-5000 multipoint gas detection panel, whereas 5000-04W is the model designation of the 4-channel wall-mounting multi-unit enclosure housing the power supply, M3 field terminal blocks, and the TAN-5000 common buzzer module.

Can the RIKEN KEIKI RS-10/RM-5000 operate on both 110V and 220V shipboard power?

Yes. The built-in power supply unit accepts a wide-range AC input from 100 VAC to 240 VAC at either 50 Hz or 60 Hz, making it directly compatible with standard marine auxiliary lighting and instrumentation circuits worldwide without manual tap adjustments.

How many gas detector channels can the 5000-04W cabinet accommodate?

The 5000-04W chassis is factory-configured with 4 dedicated slots for RM-5000 series indicator/alarm cards (such as GP-5001, NC-5001, EC-5002, or OX-5001) alongside a dedicated slot for the TAN-5000 common buzzer unit. Channel capacity is fixed by the physical backplane and cannot be expanded beyond 4 points after manufacture.

Is the RIKEN KEIKI RM-5000 indicator alarm unit explosion-proof?

No. The RS-10/RM-5000 indicator unit, TAN-5000 buzzer module, and 5000-04W enclosure are non-explosion-proof devices. They must be installed inside a gas-free safe area such as an Engine Control Room or Cargo Control Room, while connecting via shielded cables to ATEX/IECEx flameproof detector heads (such as the GD-A80) located in hazardous zones.

Can this unit replace an older RIKEN KEIKI RM-570A or RM-580 gas monitor?

Yes. The RM-5000 platform is engineered as a direct successor to the legacy RM-570A and RM-580 series. Existing field sensor cabling can be retained, and individual RM-5000 cards can even be adapted into legacy RM-570A/580 racks using the RIKEN KEIKI 5000-CC connection case.
