Why use an ATEX optical warning device?

ATEX optical warning devices play a key role in incident prevention and hazard signalling in explosive atmospheres. They are used to:

• Signal an immediate danger: gas leak, fire, threshold exceedance, system fault.
• Alert operators in the event of an operational anomaly.
• Indicate the status of an industrial process (Running / Stopped / Fault).
• Secure confined areas, technical rooms or noisy environments.
• Ensure ATEX/IECEx compliance in classified installations.
• Reduce the risk of accidents in hazardous zones.

Their high visibility, even at long distance and in challenging environments, makes them an essential component of all ATEX industrial safety solutions.

Available types of ATEX optical warning devices

ATEX LED beacons

High-intensity LED beacons with very long service life, available in several colours (red, blue, amber, green, white) with low power consumption and maximum brightness.

ATEX flashing lights

Xenon or LED strobe flashing lights providing a powerful signal, ideal for noisy environments where audible alarms are insufficient.

ATEX rotating beacons

Rotating or LED-simulated beacons providing 360° visibility; robust and suitable for work areas, ATEX vehicles and dynamic installations where visibility is crucial.

ATEX indicator lights

Status indicator lights for enclosures, electrical cabinets, pumps and motors. Multiple domes, colours and intensities available in both Ex d and Ex e versions.

Industrial applications

A2S ATEX optical warning devices are used in all environments where visual signalling is essential to ensure safety:

• Offshore platforms, refineries, oil terminals.
• Chemical, pharmaceutical and cosmetics industries.
• Storage areas for solvents, hydrocarbons and flammable liquids.
• Silos, mills and agri-food facilities (combustible dust zones 21/22).
• Hydrogen applications: electrolysers, Li-ion batteries, H₂ stations.
• Paint, varnish, resin and volatile product facilities.
• Tunnels, confined spaces, technical rooms and sensitive areas.
• SEVESO buildings, ATEX zones 1/2/21/22.

Whatever the sector, the objective remains the same: ensuring reliable and immediate visual warning.
