Overview

The Federal Signal AV1ST-120A is a dual-mode audible/visual warning device engineered for safety-critical environments requiring simultaneous strobe and buzzer alerts. Operating at 120VAC, this amber-lens strobe delivers a high-intensity visual pulse while an internal buzzer generates 85 dBA at 10 feet (95 dBA at 1 meter), ensuring clear signaling in noisy industrial or commercial settings. The unit features a surface-mount design with integrated 1/2-inch NPT pipe mounting and 4-inch electrical box mounting, providing flexible installation options for retrofits or new construction. Five lens color options (Amber, Blue, Clear, Green, Red) allow customization to meet specific application codes or visibility requirements. A twist-off lens simplifies maintenance, enabling quick access to internal components without tools. The conformally coated PCB resists moisture and contaminants, while the Type 3R enclosure protects against dust, rain, and sleet. Certified to CSA standards and UL/cUL listed, the AV1ST-120A meets rigorous safety compliance for industrial machinery, fire alarm systems, emergency exits, and public safety applications. Typical use cases include machine safety warnings, hazardous area alerts, and OSHA-compliant signaling in manufacturing plants, warehouses, and commercial facilities. The device’s dual mounting compatibility and color versatility make it a versatile solution for facilities requiring adaptable safety signaling.
