EST Edwards SIGA-AB4G-LF Fire Alarm Low-frequency Sounder Base is a specialized mounting solution designed to provide localized, high-visibility life safety notifications. This advanced base integrates a dedicated low-frequency sounder to assist in meeting stringent building codes requiring specific audible output for sleeping area compliance.

- 520 Hz low-frequency tone for superior sleeping occupant awareness - Compatible with Signature Series detectors for seamless system integration - UL 464 and UL 864 listed for reliable performance in life-safety applications - Low power consumption design to minimize overall system load - Automatic device addressing for swift installation and simplified commissioning

Compared to standard notification bases or older signaling hardware, this unit provides a significant leap in life safety efficacy by utilizing the 520 Hz frequency proven to more effectively wake occupants during an emergency. While traditional sounders often rely on higher-pitched tones that may be less effective in residential or lodging environments, this model aligns with modern NFPA 72 requirements for low-frequency signaling, ensuring your fire alarm system remains compliant and highly responsive.

Advanced Signaling and System Reliability

The engineering behind this sounder base prioritizes both acoustic performance and technical stability. By utilizing intelligent field-configurable settings, the unit allows for precise sound output levels, ensuring that emergency notification reaches intended areas without exceeding necessary decibel thresholds. Its robust construction ensures long-term operational integrity in a wide range of institutional and commercial settings, making it an essential component for high-standard life safety architecture.
