The EX 065 SCL/SCT and EX 050 SCL/SCT are explosion-proof electromechanical sirens from Sirena’s EXPRO line, designed for hazardous environments (ATEX-certified, IP66). The EX 065 models are larger and louder (up to 107 dB), while the EX 050 models are more compact, intended for installations requiring lower sound levels.

Comparison Table

 Key Considerations

• ATEX Certification: Both models are compliant, meaning they are safe for explosive atmospheres.
• Sound Coverage: Choose EX 065 for louder, wide-area alerts; EX 050 for smaller installations.
• Durability: Both are IP66-rated, ensuring resistance to dust and water ingress.
• Maintenance: Electromechanical sirens require periodic checks; the smaller EX 050 may reduce maintenance in compact setups.
