System Sensor b200s-lf-wh Addressable Sounder Base 520 Hz

Product Description

The SYSTEM SENSOR b200s-lf-wh is an intelligent addressable sounder base designed for use with addressable detector heads in fire alarm systems. It generates a low-frequency tone at approximately 520 Hz, a range demonstrated to be more effective at waking individuals in sleeping areas compared to standard high-frequency devices. The unit weighs 0.2 pounds and measures 1.60 inches by 6.85 inches by 6.85 inches. Licensed fire alarm technicians and life safety contractors install this base as part of an addressable detection system in both commercial and residential applications. It meets or exceeds UL268 and UL464 requirements.

The b200s-lf-wh is suited for residential and commercial fire alarm installations where low-frequency audible notification is required, particularly in sleeping areas. It supports multiple tone patterns, including Continuous, Temporal 3, March Time, and Temporal 4, giving system designers flexibility to meet site-specific notification requirements. The Temporal 3 pattern satisfies the NFPA 72 three-pulse fire alarm signal requirement for commercial and residential use. The Temporal 4 pattern also satisfies UL268 and UL2075 requirements as well as the private mode setting of UL 464.
