Crowcon Xgard IQ H2S

Crowcon Crowcon Xgard IQ H2S 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.

Common failures & inspection points

Sensor poisoning, depletion or aging caused by contaminant exposure or normal service, resulting in slow response, failed calibration or incorrect readings
Blocked sample path or contaminated sensing surface caused by dust, salt, oil or water, resulting in weak response or a fault indication
Calibration drift caused by sensor aging or unsuitable calibration practice, resulting in readings that do not correspond with the applied test gas
Power, battery or communication failure caused by electrical faults, depleted cells or damaged cabling, resulting in loss of indication or system fault alarms
Alarm, relay or pump malfunction where fitted caused by control or mechanical faults, resulting in missing alarms, poor sample flow or persistent fault indications

Service & Maintenance

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.
