The GH-BBJ Audible and Visual Alarm is an innovative safety alerting solution engineered for industrial, commercial, and public environments. This dual-mode warning device combines dynamic light patterns with customizable acoustic signals to enhance situational awareness and emergency response efficiency.
Featuring high-intensity multicolor LED arrays and a wide-frequency acoustic generator, the system delivers superior visual recognition exceeding 150-meter visibility range with 30% improved light penetration compared to conventional models. The acoustic module incorporates adjustable output levels, reaching up to 115dB maximum volume for effective coverage within 50-meter radius, particularly suitable for noisy operational environments.
Constructed with impact-resistant composite materials, the housing demonstrates durable performance across extreme temperatures (-40℃ to +75℃). Advanced circuit design reduces energy consumption by 20% versus comparable devices, complemented by ambient light sensors for intelligent power management. Multiple installation options including wall-mount and ceiling suspension ensure flexible deployment, while standardized interfaces simplify system integration and maintenance procedures.
Optimized for logistics centers, underground facilities, manufacturing plants, and energy stations, the GH-BBJ employs specialized flash sequences and tonal combinations to minimize environmental interference. Its directional light projection and optimized sound wave diffusion maintain consistent alert coverage in complex architectural spaces. The modular design allows customized configuration of flash frequency, color combination, and alarm duration to meet specific operational requirements.
