SHIELD S-A4023 Sounder Beacon Base (Yellow LEDs)

The SHIELD sounder beacon base featuring yellow LEDs is an addressable notification appliance designed to deliver localized acoustic warnings and distinct visual alerts directly at the detector location. Manufactured by SHIELD for seamless integration into addressable fire alarm loops, it serves both as a combination audio-visual alarm device and a detector mounting platform, eliminating the need for separate notification appliances and additional backboxes. The unit operates entirely on loop power to receive operating current and control signals directly over the two-wire line without auxiliary cabling, utilizing high-efficiency yellow LEDs for specialized visual signaling alongside high-decibel audible alarm outputs. Built with low power consumption to preserve loop capacity, selectable acoustic tones, and durable housing construction, it provides a clean, space-saving solution for commercial offices, industrial sites, and specialized facility applications.
