Fixed Gas Detection System · Gas Detection
Crowcon Xgard IQ NH3-B is a fixed gas-detection system. Fixed detectors are installed at selected machinery, cargo or process locations and connected to a central alarm or monitoring panel. Its purpose is to detect the gases supported by the installed sensor configuration and provide an alarm or measurement before hazardous concentrations remain unnoticed. Sensor technology, target gases, alarm logic and environmental suitability are model-specific and must be verified from the approved detection-system documentation. The exact model designation identifies sensor technology, target gases and certification; these must not be inferred from the family name alone.

What our service work and the manufacturer documentation say about keeping this model running.
Perform bump tests, calibration checks and functional testing according to the approved maintenance procedure for the installed detector type. Inspect sensor heads, optical paths, sample tubing, filters, batteries, cabling and junction boxes as applicable. Use only the correct certified test gas and accessories for the configured sensors. Check alarm annunciation and output relays or communication to the vessel's monitoring 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, calibration accessories, sample tubing and selected electronic or relay components recommended by the manufacturer. Test-gas cylinders and regulators must match the gases and concentrations specified for the installed system. Preserve certification and compatibility when replacing components.
