The Cooper EL-HSR conventional wall-mounted indoor audio fire horn strobe represents an elite, high-specification notification appliance belonging to the industry-leading Wheelock Eluxa product line.
Specifically styled with an ultra-sleek, modern single-gang architecture, this high-performance signaling device offers architects, consulting engineers, and facility operators a visually striking profile that features no visible mounting screws.
It satisfies the most rigorous life safety aesthetic and performance parameters across clean commercial real estate, educational campuses, and institutional facilities.
By engineering advanced high-efficiency LED technology directly into the optical flash core, the high-performance Cooper EL-HSR drastically lowers system electrical strain. Operating dynamically on a 24V line, it delivers the industry’s lowest current draw across its full multi-candela spectrum.
This exceptional energy efficiency allows project managers to dramatically reduce wire sizing, lengthen cable runs, and minimize the number of external NAC auxiliary power booster supplies needed across a zone layout.
Unmatched system versatility is built straight into the core electronics framework. The Cooper EL-HSR introduces a unique multi-alert protocol capable of managing distinct fire alarm and carbon monoxide (CO) emergency broadcasts simultaneously over the exact same two wires. Paired with three field-programmable horn cadences (Continuous, T3, and T3/T4) and six selectable light intensities, this multi-mode appliance successfully replaces a wide range of legacy single-purpose devices.
Installation convenience and circuit reliability are completely integrated into the system layout. The premium Cooper EL-HSR unit supports an intelligent pre-wire base configuration, allowing technical teams to test wiring runs for grounds and faults safely before attaching the active notification head assembly. Built with a robust, impact-resistant Lexan lens module over a bold red fire-retardant plastic chassis, the device delivers a durable, low-maintenance protective layer designed to stand guard over building occupants for years to come.

Q1: What are the main benefits of using LED-based horn strobes like the Cooper EL-HSR?
A: Advanced LED technology achieves the industry’s lowest current draw across the entire candela spectrum. Legacy xenon flash units can consume up to three times more current, meaning the EL-HSR allows you to wire far more signaling devices per individual circuit. This helps optimize systems by using fewer booster power panels and smaller wire gauges.
Q2: How does the two-wire simultaneous Fire and Carbon Monoxide signaling function operate?
A: The device features an intelligent internal decoder card that interprets complex signals from a single pair of supervised wires. This enables the appliance to seamlessly switch its sound output pattern between a standard Fire notification and a dedicated Carbon Monoxide warning cadence without requiring separate dedicated loops.
Q3: Which legacy Wheelock models does this specific Eluxa module replace?
A: The EL-HSR serves as the official high-efficiency factory upgrade designed to fully replace older Wheelock LHSR3 and HSR conventional horn strobe series assemblies, instantly updating your facility with lower power load metrics.
Q4: Can this audio-visual signaling flasher be deployed securely inside outdoor industrial locations?
A: No. The appliance enclosure is explicitly rated for internal, dry environment applications only, with an indoor climate window spanning 32°F to 122°F. For wet open spaces or exterior canopy routes, you must source a specialized weatherproof outdoor notification variant from the Eaton series map.
Q5: Can I change the candela output intensity on site during final system setup?
A: Yes, absolutely. The device features a highly accessible multi-candela slider switch on its back casing. This allows technicians to easily set output levels to 15, 30, 75, 110, 135, or 185 cd on-site, providing total compliance with varying room geometry demands.
