Chinese Ex Certification

• Ex db IIC T6/T5 Gb
• Ex db ib IIC T6/T5 Gb
• Ex tb IIIC T80°C/T95°C Db

These certifications allow safe use in Zone 1 & Zone 2 for gas, and Zone 21 & Zone 22 for dust environments.

IP66 Weather & Dust Protection

Built with a rugged aluminum alloy enclosure and tempered glass lampshade, the warning lights offer IP66 protection, ensuring:

• Full resistance to dust penetration
• Protection from strong water jets
• Excellent performance in heavy rain, humidity, or industrial washdown environments

This makes them ideal for outdoor installations and maritime, chemical, and high-dust facilities.

Wide Voltage Range for Easy Integration

Both models support multiple AC and DC voltage inputs, offering flexibility for various installation needs.

Without Buzzer

• 20–40V AC/DC
• 127–250V DC
• 100–250V AC (50/60Hz)

With Buzzer

• 100–250V AC, 5W
• 127–250V DC, 5W
• 20–40V AC/DC, 5W

Their wide compatibility simplifies integration with existing electrical systems.

High-Output Buzzer Options

The CZ6474121B includes an optional high-volume buzzer designed for noisy industrial environments. Features include:

• Over 95 dB alert with one buzzer
• Up to 125 dB with dual buzzers
• Ideal for emergency warnings, fault notifications, or operational signaling

This combination of sound and light maximizes safety response times.

Temperature Ratings for Extreme Environments

These warning lights are engineered for a wide temperature range:

• Minimum: –60°C / –40°C
• Maximum: +40°C (T6) / +55°C (T5)

This enables safe use in:

• Cold storage and high-altitude sites
