FAQ

Why choose ATEX signaling rather than a standard device?

The ATEX signaling is specially designed to work in explosive areas (gas, dust, vapors). Unlike conventional devices, ATEX optical and sound alarms are certified to eliminate any risk of spark or overheating, ensuring the safety of people and regulatory compliance.

What is the difference between an optical, sound and combined ATEX warning?

• TheADEX SOUND AREA Emits a powerful and adjustable auditory signal, ideal in areas with high visibility.

• TheATEX optical alarm diffuses a light signal (flash or gyrophare) to attract attention, even remotely.

• TheATEX Combined Alarm Associate both to ensure that the alarm is perceived in very noisy or cluttered environments visually.

What standards and certifications meet your ATEX signaling products?

All our signaling equipment complies with the European Directive ATEX 2014/34 / EU and standards Iecex. They also meet international safety standards for explosive atmospheres, ensuring reliable use in the petrochemical, offshore, pharmaceutical or agri-food sectors.

What are the advantages of the GRP for ATEX optical and sound alarms?

The GRP is lightweight, anticorrosion and perfectly adapted to aggressive environments (maritime areas, offshore, chemical atmospheres). It resists UV, bad weather and offers excellent mechanical stability, reducing maintenance needs.

Why choose stainless steel for an ATEX warning?

The choice depends on your environment:

• GRP : Ideal if lightness, chemical resistance and sustainability in aggressive circles are priorities.

• Requirements of Selection of equipment According to categories

• Associated standards (EN, IECEX, ATEX) and marking

• Modes of protection (Ex d, ex, ex i, ex p, etc.)

Detection technologies: how does it work?

1. Gas detectors

• Principles (electrochemical, catalytic, infrared, pellistor, etc.)
• Targeted gases (CH4, H2S, CO, CO2, etc.)
• Fixed sensors VS Portable
• Criteria of choice (answer, sensitivity, response time)

2. Flame detectors

• UV, IR, UV / IR sensors
• Typical applications (flammable gas leaks, fires)
• Time of detection, immunity with false alerts

3. Multi-sensor detectors & handsets

• Smoke + heat, optical + thermal
• Advantages in complex environments

4. Other sensors / techniques

• Thermal / thermovelocimetric detectors
• Aspirations, Vesda systems
• Optical fiber detection (if applicable)

Which ATEX detector choose according to the gas?

The choice of ATEX detector Depends on the type of gas to monitor and site conditions.

• For the combustible gases (methane, propane, butane ...), we often use catalytic sensors or Infrared (IR).

• For the toxic gases like CO, H₂S, nh₃, the electrochemical sensors are the most adapted.

• The Photo-ionization detectors (PID) Suitable for volatile organic compounds (VOCs).
  The choice is also done according to the ATEX zone (0, 1, 2/20, 21, 22) and certification requirements.
  
  A2S experts can help you define the safest technology and in accordance with your industrial environment.

What is the maintenance required for an ATEX detector?

A ATEX detector must be maintained regularly To guarantee its reliability:

• Visual inspection and periodic cleaning of the sensor.

• Calibration and Response Test Target gas (every 6 to 12 months depending on the conditions).

• Replacing detection cells at the end of life.
  One Preventive maintenance plan Ensures compliance with ATEX standards and extends the life of the equipment.
  A2S offers Maintenance contracts and on-site calibration For all his models.

What does ZONE 1 / ZONE 2 mean?

These classifications define the level of risk of explosion due to the presence of gas:

• Zone 1: the risk is likely During normal operation (occasional presence of explosive gas).

• Zone 2: the risk is rare and short-term, usually during an incident or accidental leak.
  The equipment installed in these areas must be Certified ATEX and designed to avoid any source of inflammation (sparks, warm-up, electrostatic discharge ...).

What is the typical life of an ATEX sensor?

The service life depends on the Technology used :

• Electrochemical : 2 to 5 years depending on gas and ambient conditions.

• Catalytic : About 3 to 5 years.

• Infrared (IR) : up to 10 years with adapted maintenance.
  Dusty, wet or corrosive environments can reduce longevity.
  One Maintenance and Recalibration Program Regular is essential to maintain accuracy and compliance.

How to validate ATEX compliance?

ATEX compliance is valid according to the European Directive 2014/34 / EU, which frames the manufacture and use of equipment for explosive areas.
To be consistent, you need:

1. Use Certified ATEX / IECEX Certified Hardware corresponding to the installation area.

2. Dispose of CE CE examination certificate and a ATEX marking Clear (eg Ex d IIC T6 GB).

3. Make a Compliance assessment of the installation by a competent body.

4. Keep the technical documentation and periodic inspection reports.
   A2S accompanies its customers in the Validation and traceability equipment to ensure sustainable security and compliance.
