Fixed Gas Detection System · Gas Detection
The Riken Keiki RM-5000 is a fixed gas-detection system. It is normally installed with sensors in hazardous spaces and controller/alarm equipment in an attended position. It is designed for continuous warning of flammable, toxic or oxygen-related atmospheric hazards. In operation, fixed diffusion or sampled sensors transmit concentration/status to a central controller. Compared with neighbouring models, the relevant differences are sensor technology, channel count, alarm logic, networking and shutdown interfaces; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on sensor calibration, sample lines, controller faults, alarms, shutdown relays and power. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Perform manufacturer-approved bump, calibration or functional tests and verify the actual fitted gas/sensor configuration. Inspect sampling hoses/filters/pumps or optical paths as applicable, battery/power, alarms and controller interfaces. Confirm sensor locations remain suitable after vessel modifications and maintain valid calibration gas where required.
Carry manufacturer-approved sensors where onboard replacement is permitted, filters, sampling hose, pump consumables, batteries/chargers, fuses and selected controller or relay modules. Maintain suitable in-date calibration gas and regulators for the installed sensor types.
