MEDC XB15 Explosion-Proof Xenon Beacon

The MEDC XB15 beacon (now manufactured under the Eaton Crouse-Hinds MEDC brand) is a rugged explosion-proof Xenon beacon designed to deliver reliable visual alarm signaling in hazardous area installations across oil, gas and petrochemical facilities, onshore and offshore. Built around a high-intensity Xenon flashtube with a light output range of 5 to 21 Joules depending on configuration, the XB15 provides clear, attention-getting visual warning even in bright daylight or heavy fog conditions typical of process plants and marine environments.

Hazardous Area Certification

The XB15 is certified for use in Zone 1 and Zone 2 hazardous locations under ATEX and IECEx schemes, with UL-listed variants also available for North American installations. Its flameproof (Ex d) enclosure prevents an internal spark or arc from igniting a surrounding explosive atmosphere, making it suitable for installation in refineries, offshore platforms, chemical processing plants, and other facilities where flammable gases or vapors may be present.

Technical Specifications

Rugged GRP Construction

Housed in a glass-reinforced polyester (GRP) enclosure with a protective stainless steel wire guard over the lens, the XB15 is built to withstand the corrosion, UV exposure, vibration and physical impact common in offshore and coastal industrial environments. The beacon carries a high IP66/IP67 ingress protection rating, ensuring reliable operation even when subjected to washdown, heavy rain or sea spray.

Supervised Alarm Circuit

The XB15 includes a supervisory diode and four-wire lead connection, allowing it to be integrated into a supervised alarm circuit that can detect wiring faults or beacon failure, an important feature for life-safety and process-critical alarm systems where a failed visual indicator could delay evacuation or fault response. Units are available in a range of lens colors (including red, amber, blue, green and clear) to match specific alarm coding schemes used across a facility.

Typical Applications

The XB15 is widely deployed as a process fault indicator, fire and gas detection alarm, emergency evacuation signal and general-purpose hazardous area visual alarm across oil and gas production facilities, LNG terminals, offshore platforms, petrochemical plants and marine vessels. It is frequently specified alongside MEDC and Eaton Crouse-Hinds audible alarm sounders to form a combined audio-visual alarm point at each hazardous area location.

Voltage and Mounting Options

The XB15 is available in AC and DC voltage variants (commonly 24V DC, 110V AC and 230V AC) and can be supplied for direct mount or pipe mount installation, allowing flexibility when retrofitting into an existing hazardous area alarm system or specifying a new installation. Units can also be supplied pre-painted to customer specification to match facility color-coding standards.

Alarm Coordination and Signal Coding

Because hazardous area facilities often need to distinguish between multiple alarm conditions — such as gas detection, fire, process fault and general evacuation — the availability of the XB15 in several lens colors allows a plant to implement a clear visual coding scheme across its alarm points. Combined with the beacon’s selectable flash rate and light output, this makes it straightforward to differentiate a critical gas alarm beacon from a lower-priority process fault indicator at a glance, even from a distance or through smoke and fog.

Integration with Fire and Gas Systems

The XB15 is commonly wired into a facility’s fire and gas (F&G) detection and alarm system, triggered automatically by the central F&G logic solver when a detector confirms a gas release, fire condition or other hazardous event. Its supervised circuit design means that a broken wire or beacon failure is reported back to the control system as a fault condition rather than failing silently, which is a critical requirement for safety instrumented systems operating to IEC 61508/61511 functional safety principles.

Selecting the Right Configuration

When specifying an XB15 beacon, engineers typically need to confirm the required light output (Joule rating), lens color, supply voltage, hazardous area certification (ATEX, IECEx or UL) and mounting style (direct or pipe mount) to match the installation. Because these variables affect both the part number and the beacon’s visibility performance in a given installation, Seven Star LLC can help cross-reference an existing installed base or a project specification against the current XB15 range to confirm the correct configuration before ordering.

Seven Star LLC also stocks compatible MEDC audible alarm sounders and junction boxes, allowing a complete combined audio-visual alarm point to be sourced from a single supplier for new installations or panel replacements.

Why Choose Seven Star LLC

Seven Star LLC supplies genuine MEDC and Eaton Crouse-Hinds hazardous area signaling equipment, including the XB15 Xenon beacon range, to oil and gas operators, EPC contractors and marine facilities across Oman and the wider GCC region. Our team can help confirm the correct voltage, lens color, mounting configuration and certification scheme for your hazardous area alarm system.

Because the XB15 remains one of the most widely installed beacon models across legacy and current MEDC and Eaton Crouse-Hinds hazardous area alarm systems, replacement units are frequently sourced for maintenance and panel upgrade projects rather than new-build installations, and Seven Star LLC can support both scenarios.

Our team can also advise on lead times for factory-specific paint finishes or certification documentation packages required for offshore procurement.

Cross-referencing older MEDC part numbers against current production is a service we regularly provide to facilities running long-life alarm system installations.
