Fixed Gas Detection System · Gas Detection
Riken Keiki Riken EC-600 NH3 is identified in the source list as a fixed gas detection system. It is installed at selected machinery, cargo or process locations and connected to a central alarm or monitoring system. Its purpose is to detect the gas or gases supported by the installed sensor configuration and warn the crew before an unsafe atmosphere remains unnoticed. The source record provides no additional model-specific operating figure beyond the listed designation and category. Sensor technology, target gases, alarm logic, sampling arrangement and environmental certification are model-specific and must be verified from the approved detector documentation. The exact model designation distinguishes sensor set, sampling arrangement, alarm functions and certification from neighboring detectors; refer to the manufacturer documentation for the exact configuration.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
Perform bump tests, calibration checks and functional testing in accordance with the approved procedure for the installed detector type. Inspect sensor heads, sample paths, filters, batteries, cabling, pumps and junction boxes as applicable. Use only the correct certified test gas and accessories for the configured sensors. Verify local alarms and any outputs to the vessel's alarm or shutdown system. Replace life-limited sensing elements according to manufacturer guidance and record the work. Refer to the approved documentation for exact calibration intervals, alarm settings and environmental limits.
Keep model-correct sensor cartridges or cells, filters, batteries where applicable, pump consumables, calibration accessories and selected electronic or relay components recommended by the manufacturer. Test-gas cylinders and regulators must match the configured sensors. Replacement components must preserve the approved certification.
