Description
Features
- Wall-mounted, die-cast aluminum alloy housing with explosion-proof cavity walls no less than 5mm thick for superior explosion protection.
- Industrially designed for water and dust resistance (IP66 rating).
- Explosion-proof certifications: Ex db IIC T6 Gb, Ex tb IIIC T80℃ Db for use in gas and dust explosion-hazardous areas.
- 8Ω impedance input, 50W output, compatible with most explosion-proof telephones.
- Large cavity allows for expansion to a constant-pressure explosion-proof speaker (with constant-pressure input), an active explosion-proof speaker (with built-in power amplifier), or an IP explosion-proof speaker (with built-in IP broadcast amplifier).
- G1/2 (4-point) internal thread explosion-proof connector for easy connection to explosion-proof flexible tubing.
- Built-in wiring terminal for convenient on-site wiring, accommodating 0.2-2.5㎡ audio cables.
- Spiral explosion-proof sealing surface for easy installation and maintenance.
