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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-frequency 520 Hz tone output shown to be more effective for waking sleeping occupants\u003c\/li\u003e\n  \u003cli\u003eSupports ANSI Temporal 3, Temporal 4, Continuous, and March Time tone patterns\u003c\/li\u003e\n  \u003cli\u003eMeets or exceeds UL268, UL464, and UL2075 listing requirements\u003c\/li\u003e\n  \u003cli\u003eTemporal 4 pattern satisfies UL 464 private mode setting\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with addressable detector heads in the Select Series Mounting Base platform\u003c\/li\u003e\n  \u003cli\u003eWhite finish for standard ceiling or wall installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with addressable detector heads as part of an intelligent addressable fire alarm system.

Disconnect system power and follow the fire alarm control panel manufacturer lockout procedures before removing or installing any detector head or sounder base. Do not apply power until the detector head is fully seated and the base is secured to its mounting surface. Refer to the System Sensor installation manual for wiring configuration and addressable loop connection details.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTone Frequency\u003c\/strong\u003e: approximately 520 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTone Patterns\u003c\/strong\u003e: Continuous, ANSI Temporal 3, March Time, Temporal 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 1.60 inches x 6.85 inches x 6.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Type\u003c\/strong\u003e: Sounder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL268, UL464, UL2075\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition\u003c\/strong\u003e: New\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduction Status\u003c\/strong\u003e: Active\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SYSTEM SENSOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: b200s-lf-wh\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SYSTEM SENSOR","offers":[{"title":"Default Title","offer_id":51268653482290,"sku":"B200S-LF-WH","price":153.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912888.jpg?v=1780704844","url":"https:\/\/voomisupply.com\/products\/system-sensor-b200s-lf-wh-addressable-sounder-base-520-hz","provider":"Voomi Supply","version":"1.0","type":"link"}
