Cooper Wheelock EL4XSPST-FR Eluxa NEMA 4X Outdoor Speaker Strobe

The Cooper Wheelock EL4XSPST-FR is a weatherproof fire alarm speaker/strobe notification appliance with a red housing, clear LED strobe lens, and FIRE identification lettering, designed to provide audible emergency messages and visual alerts in demanding indoor and outdoor environments. Part of the Wheelock Eluxa outdoor notification appliance family, this combination speaker/strobe provides six field-selectable visual intensity settings of 15, 30, 75, 110, 150, and 185 candela, allowing installers to configure strobe output according to the protected area's notification requirements. The unit incorporates a high-efficiency speaker operating over a 400-4000 Hz frequency range for integration with compatible fire alarm voice evacuation and emergency communication systems. Its NEMA 4X-rated enclosure supports applications exposed to moisture, dust, corrosive environments, and severe temperature conditions, including parking garages, industrial facilities, building exteriors, transportation terminals, cold storage facilities, and chemical processing areas.

The EL4XSPST-FR incorporates a field-selectable 25 or 70.7 VRMS speaker with adjustable power taps of 1/8, 1/4, 1/2, 1, and 2 watts at 25 VRMS, or 1/8, 1/4, 1/2, 1, 2, 4, and 8 watts at 70.7 VRMS. The speaker delivers a reverberant sound pressure level of 76 to 94 dBA at 10 feet, depending on the selected voltage and wattage setting, providing flexibility for emergency voice notification in areas with differing acoustic requirements. The integrated LED strobe operates from a nominal 24 VDC notification appliance circuit with a regulated operating range of 16-33 VDC or full-wave rectified voltage. Its six-position candela selector allows the installer to match visual signal intensity to the application, while the energy-efficient LED design limits maximum current consumption to 0.206 amps at 185 candela on regulated DC power. The strobe produces one flash per second and features a 20-millisecond light pulse duration meeting the applicable NFPA 72 notification requirements.

The Cooper Wheelock EL4XSPST-FR features a NEMA Type 4X and IP66-certified weather-resistant enclosure designed to withstand dust, water exposure, corrosion, and demanding environmental conditions. Its UV-stabilized engineered plastic housing is suitable for operation from -40 F to 150 F (-40 C to 66 C) at up to 95% relative humidity. The appliance measures approximately 8 inches high, 6.5 inches wide, and 4.5 inches deep and weighs approximately 2.3 pounds. It is supplied with a compatible EL4XBB surface-mount back box featuring pre-wire and pre-test terminal connections to simplify installation and circuit verification. A self-supporting hanging hinge allows technicians to position the notification appliance during wiring and final assembly. The unit supports wall or ceiling mounting and accepts 12 to 18 AWG conductors through its screw terminal connections. Separate speaker and strobe circuits allow the audible evacuation system and visual notification circuit to be connected and supervised independently according to the fire alarm system design.

The EL4XSPST-FR supports Wheelock synchronized strobe operation through compatible fire alarm control panels, DSM synchronization modules, Wheelock power supplies, and SAFEPATH emergency communication equipment. Its LED strobe is designed for compatibility with listed Wheelock RSS-based notification appliances and Exceder LED3 devices, allowing integration into compatible existing notification systems and expansions. The appliance supports synchronized visual signaling and applicable audible silence functionality when operated with the appropriate control equipment. The series is listed to UL 1480 for fire protective signaling speakers, UL 1638 for visual signaling appliances, and UL 1971 for visual fire alarm notification, with applicable CAN/ULC S541 and S526 certifications, California State Fire Marshal recognition, and Factory Mutual approval. Its NEMA 4X enclosure also meets applicable UL 50 and UL 50E environmental requirements. Designed for installations governed by NFPA 72 and applicable fire alarm codes, the Cooper Wheelock EL4XSPST-FR combines configurable voice evacuation output, six selectable LED strobe intensities, weather-resistant construction, and simplified surface-mount installation for reliable audible and visual fire alarm notification in commercial, institutional, and industrial environments.
