Wheelock ELSPSTR Red LED Speaker Strobe

The Cooper Wheelock ELSPSTR is a wall-mounted Eluxa Series high-fidelity LED speaker strobe designed for commercial fire alarm, emergency voice evacuation, and mass notification systems. Featuring a red housing, clear Lexan lens, FIRE lettering, and six field-selectable candela settings of 15, 30, 75, 110, 135, and 185 cd, it combines audible and visual notification in one appliance. The speaker supports 25/70.7 VRMS audio systems, selectable power taps, and a 300-8,000 Hz frequency response, while the LED strobe operates on regulated 24 VDC power. Its low-profile construction, included pre-wire mounting plate, and synchronization compatibility simplify indoor wall installation.

Cooper Wheelock ELSPSTR Eluxa LED Speaker Strobe, Red, Wall Mount, 15-185 Candela

The Cooper Wheelock ELSPSTR Eluxa High-Fidelity Speaker Strobe provides combined audible and visual emergency notification for commercial and institutional fire alarm systems. Manufactured by Eaton under the Wheelock brand, this wall-mounted notification appliance integrates a high-fidelity speaker and multi-candela LED strobe in a compact, red enclosure with white FIRE lettering and a clear Lexan lens. The speaker reproduces emergency voice announcements and evacuation tones from compatible fire alarm voice evacuation equipment, while the LED strobe provides visual warning during alarm conditions. Designed for offices, schools, healthcare facilities, hotels, warehouses, and public buildings, the ELSPSTR supports coordinated emergency communications, mass notification, and fire alarm signaling where both speech intelligibility and visual notification are required.

The ELSPSTR features a high-fidelity speaker with a 300-8,000 Hz frequency response, supporting intelligible voice messages and audible emergency tones. The speaker operates on 25 or 70.7 VRMS distributed audio circuits, with selectable power taps ranging from 1/8 to 2 watts at 25 VRMS and 1/8 to 8 watts at 70.7 VRMS, according to Eaton's May 2025 technical datasheet. Published reverberant sound pressure levels range from approximately 74 dBA at the lowest tap to 85 dBA at 2 watts on 25V systems, with higher outputs available at the designated 70.7V settings. The speaker's selectable wattage allows system designers to balance sound coverage, amplifier loading, and intelligibility across multiple notification zones. Audio is supplied by a compatible voice evacuation amplifier; the ELSPSTR does not contain a standalone message generator or fire alarm control panel.

The Cooper Wheelock ELSPSTR incorporates an energy-efficient LED strobe with six field-selectable candela settings of 15, 30, 75, 110, 135, and 185 cd. The visual notification circuit operates from a regulated 24 VDC supply within a 16-33 VDC operating range, with manufacturer-published maximum UL/ULC current ratings of approximately 17 mA at 15 cd through 161 mA at 185 cd in the May 2025 series datasheet. The strobe flashes at least once per second and supports synchronized operation through compatible Wheelock DSM synchronization modules, PS Series power supplies, and SAFEPATH equipment. The appliance uses separate audio and strobe circuit connections, allowing the speaker and visual signaling functions to operate through their respective system outputs. Its LED technology meets the applicable NFPA 72 light-pulse duration requirements and supports approved installations with compatible Wheelock xenon and LED strobes within the same notification area.

The ELSPSTR features a low-profile, UV-stabilized engineered plastic housing designed for indoor wall-mounted installations. Eaton's Eluxa speaker strobe datasheet specifies a face dimension of approximately 6.35 inches high by 4.56 inches wide, with a low-profile appliance body and a snap-on speaker grille. The included pre-wire/pre-test mounting plate with capture hinge allows installers to terminate and verify field wiring before attaching the notification appliance. Screw terminals accommodate 12-18 AWG conductors, while compatible mounting options include the ELSPKBB surface backbox and standard 4-inch square electrical boxes with a minimum 2-1/8-inch depth. The ELSPSTR operates from 32 F to 122 F (0 C to 50 C) at up to 93% relative humidity and is intended for indoor use only. Manufacturer documentation identifies applicable UL 1480 and UL 1971 speaker and visual signaling listings, CAN/ULC-S541 and CAN/ULC-S526 certifications, and CSFM approval. The appliance carries a three-year limited manufacturer warranty. Installation must follow Eaton's speaker and strobe circuit specifications, amplifier power calculations, visual notification coverage requirements, and applicable NFPA 72 standards.
