Eaton has developed the Wheelock Exceder LED3 Low Frequency Sounder Strobes (LFHSK3/LFHSH3) and Sounders (LFHNK3) to meet the National Fire Protection Association (NFPA) low frequency sounder requirements for sleeping rooms - NFPA 72 for fire alarm and NFPA 720 for Carbon Monoxide (CO) alarm. In a single device, the Exceder LED Low Frequency Sounders can provide alarm signals for dual applications - T3 (Fire) and T4 (CO) tones. Eaton offers low frequency sounder strobe models for both low and high candela settings, ideal for retrofits and new construction.
The Exceder LED3 Low Frequency Sounder Strobes and Sounders feature multiple 520 Hz modes of operation: T3 (fire), T4 (CO), Continuous, T3/T4 Sync Control.
Like the entire Wheelock Exceder LED3 product line, the Low Frequency Sounder Strobes feature an advanced power saving LED technology in a sleek, modern, single-gang enclosure that will provide high energy efficiency and an aesthetically pleasing low profile design that will blend with the building's interior décor. LFHSK3 strobe models include a 110 candela setting, and LFHSH3 strobe models include a 177 candela setting.
Providing a sleek aesthetic appearance, the Exceder LFHSK3/ LFHSH3 and LFHNK3 models feature one of the industry's smallest footprints and a sleek, modern, low-profile design. Installers will benefit from its comprehensive feature list, multiple 520 Hz modes of operation, lowest current draw, no tools needed for setting changes, and convenient mounting options. The LFTP trim plate, which is included in all LFHNK3/LFHSK3/LFHSH3 models, allows for ease of installation for retrofit projects that have single-gang backboxes installed. These products are suitable for indoor wallmount applications. The Sounder and Sounder Strobe models are for 24V operation.
Eaton's Exceder LED3 strobes meet the 20 millisecond light pulse duration requirements of the 2016 edition of NFPA 72. By meeting this latest requirement, xenon and LED devices can now be in the same field of view. With the Exceder LED3 line, Eaton now offers a full range of products with low and high candela settings ideal for both retrofits and new construction.
The Exceder LED3 Low Frequency Sounders and Sounder Strobes are UL Listed for indoor use under Standard 1971 and 464 and ULC under S525 and S526.
In addition, the Wheelock Exceder LED3 product line has been UL/ ULC listed as compatible with all Fire Alarm Control Panels (FACP) and accessories that have been determined to be compatible with Wheelock RSS strobe-based products including the RSS, CH, E, EH, ET, ST, HS, MT, S8, SA, STH and Z Series.
