The Wheelock Eluxa weatherproof series EL3RSPK/EL4XSPK speaker and EL3RSPST/EL4XSPST speaker-strobe appliances are designed for easy installation with a pre-wire capable EL3RBB mounting plate, or EL4XBB back box. All Eluxa weatherproof models are for indoor/outdoor use and wall or ceiling mount. The EL3RSPK/EL4XSPK and EL3RSPST/EL4XSPST Series Multi-Candela Speaker Strobes are designed for multiple power requirements with high dBA output at each power tap. The design incorporates a high efficiency speaker for maximum output at minimum power across a frequency range of 400-4000Hz. The cutting-edge solution delivers optimal performance thanks to its NEMA type 3R and 4X ratings, which make it resistant to corrosion and ice formation. The IP54 and IP66 ratings provide superior protection against dust and water, making it ideal for areas of high humidity, extreme heat, or severe cold. With six candela settings in a single device, Eluxa features one of the industry‘s lowest current draws across the full candela range. The Eluxa outdoor product line reduces overall power consumption, allowing for more appliances on each circuit (NAC) and fewer power supplies.
