E2S Warning Signals expands marine and offshore certification portfolio with new DNV, MED, and MER approvals across explosion proof loudspeaker range

E2S Warning Signals, the global leader in high performance audible and visual signalling devices for hazardous areas, has announced the addition of DNV, MED, and MER approvals to a selection of its hazardous area loudspeakers. This expansion strengthens the company’s offering for marine, offshore, and shipboard safety systems where certified, robust, and acoustically efficient equipment is essential.

Engineering grade approvals for demanding marine environments
The newly approved models – D1xL1F, D1xL2F, D1xL2H, D2xL1F, D2xL2F, D2xL2H, E2xL15F, and E2xL25F – are part of E2S’s established portfolio of flameproof/explosion proof and increased safety loudspeakers designed for hazardous gas and dust atmospheres.

DNV certification:
DNV approval confirms that these loudspeakers meet stringent requirements for mechanical integrity, environmental resilience, and long term reliability. The certification process evaluates ingress protection, corrosion resistance, and compliance with marine vibration and EMC standards – critical for installations on vessels, FPSOs, and offshore platforms.

MED (Marine Equipment Directive) wheel mark:
The MED wheel mark ensures compliance with international maritime safety standards for equipment installed on EU flagged vessels. MED approval enables shipbuilders and system integrators to specify E2S loudspeakers without requiring additional conformity assessment.

MER (UK Marine Equipment Regulations):
MER approval provides equivalent assurance for UK flagged vessels following regulatory divergence from the EU. This ensures continuity for operators and OEMs supplying into both EU and UK maritime markets.

Technical advantages of the E2S explosion proof loudspeaker range:
The approved speakers share a set of engineering characteristics that make them particularly suited to hazardous marine environments:

1. High performance acoustic output

• Output options from 15W to 25W, depending on model
• Optimised flare geometries for efficient sound dispersion
• Wide frequency response for clear voice messaging and alarm tones
• High SPL performance suitable for high noise environments such as engine rooms, pump rooms, and deck machinery areas

2. Corrosion resistant construction

• Marine grade aluminium and PPS (glass reinforced Polyphenol Sulphide) enclosures with UV stable, anti static properties
• Marine grade stainless steel fixings
• High resistance to salt spray, chemical exposure, and long term UV degradation

3. Hazardous area protection

• Certified for Zone 1, 2, 21 & 22, and Class I/II Division 1 & 2 (model dependent)
• Flameproof/Explosion proof (Ex d) and increased safety (Ex ec) protection concepts
• High ingress protection ratings (typically IP66/67) for exposure to washdown, spray, and immersion.

4. Electrical and installation flexibility

• 25V, 70V and 100 V line transformer options
• Multiple cable entry configurations
• Large termination chambers for easier installation and maintenance

5. Engineered for harsh marine conditions, these loudspeakers are designed to withstand:

• High vibration levels
• Wide temperature ranges
• Continuous exposure to saltwater and humidity
• Mechanical shock and impact

This combination of performance, durability, and certification makes the E2S range suitable for safety critical applications including general alarm systems, PAGA systems, and emergency shutdown signalling.
