Eaton has developed the Wheelock Eluxa low frequency sounders (ELFHN) and sounder strobes (ELFHS) to meet the National Fire Protection Association (NFPA 72) low frequency sounder requirements for sleeping rooms for both fire alarm and carbon monoxide (CO) signaling. In a single device, the Eluxa low frequency sounders features both low and high candela settings and alarm signals for dual applications - T3 (fire) and T4 (CO) tones. High efficiency, LED technology Eaton’s high energy efficient technology leads the industry in lowest current draw across the full candela range, which reduces overall power consumption and costs in fire alarm systems. As the first notification appliances in the industry to utilize LED as the light source, this breakthrough and patented optical design, resulting in best-in-class efficiency, enables material and system cost savings, allowing for a greater number of appliances on the notification appliance circuit and fewer power supplies. All strobe models feature 110 and 177 candela settings for both wall- and ceiling- mount models.
