Alarms & signaling devices

Eaton has developed the Wheelock Eluxa low frequency sounders (ELFHN/ELFHNC) and sounder strobes (ELFHS/ELFHSC) 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). The low frequency sounders can replace a facility’s existing appliances, utilizing the same single pair of wires that are currently installed, offering a simple retrofit to meet new codes for sleeping rooms.
