Featuring a red housing, clear lens, FIRE lettering, and six selectable candela settings of 15, 30, 75, 110, 150, and 185 cd, it combines high-efficiency LED signaling with selectable horn patterns. The appliance operates from 16-33VDC/FWR and provides up to 90 dBA at 10 feet, with NEMA 3R and IP54 environmental protection for indoor and outdoor installations.

Eaton Wheelock EL3RHS-FR Eluxa Outdoor LED Horn Strobe

The Eaton Wheelock EL3RHS-FR Eluxa Series Outdoor Horn Strobe is a combination audible and visual notification appliance designed for fire alarm signaling in indoor and outdoor commercial environments. Manufactured by Eaton under the Cooper Wheelock brand, the EL3RHS-FR combines a selectable electronic horn with an energy-efficient LED strobe in a red, UV-stabilized enclosure featuring a clear Lexan lens and FIRE lettering. The device provides six field-selectable candela settings of 15, 30, 75, 110, 150, and 185 cd, allowing installers to configure visual notification intensity for the mounting location and applicable fire alarm design requirements. Its weather-resistant construction supports installation on building exteriors, parking garages, loading areas, outdoor walkways, and other locations exposed to changing environmental conditions.

The EL3RHS-FR operates from a nominal 24V notification appliance circuit with a regulated operating range of 16-33VDC or full-wave rectified (FWR) power. Its LED strobe flashes once per second and produces a light pulse meeting the 20-millisecond maximum duration requirement referenced in NFPA 72. The integrated horn provides Continuous, Temporal 3, and synchronized Temporal 3/Temporal 4 signaling options, with field-selectable high and low sound output. At 24V, the manufacturer specifies a reverberant sound pressure level of 90 dBA at 10 feet on the high setting and 86 dBA on the low setting. Maximum current consumption varies according to the selected candela, horn setting, and power waveform, ranging from 63mA at 15 cd to 230mA at 185 cd when operating on DC power with the horn set to high output.

Designed for weather-resistant fire alarm notification systems, the Wheelock EL3RHS-FR carries a NEMA Type 3R and IP54 environmental rating when installed according to the manufacturer's instructions with the appropriate mounting plate. Its enclosure is constructed from textured, UV-stabilized engineered plastic and is intended for operation in temperatures from -40 F to 150 F (-40 C to 66 C) with relative humidity up to 95%. The appliance supports wall or ceiling mounting and includes a pre-wire/pre-test mounting arrangement that allows installers to terminate and verify field wiring before attaching the notification device. Two-wire connections accommodate 12-18 AWG conductors. These features make the EL3RHS-FR suitable for outdoor pedestrian areas, parking structures, transportation facilities, industrial locations, and humidity-prone indoor environments requiring combined audible and visual emergency notification.

The Eaton Wheelock EL3RHS-FR supports synchronization through compatible fire alarm control panels incorporating the Wheelock synchronization protocol, Wheelock Dual Sync Modules (DSM), or approved Wheelock power supplies. Manufacturer-documented compatibility includes approved Wheelock RSS strobe-based products and Exceder LED3 appliances, supporting integration into compatible existing notification systems and new installations. The Eluxa outdoor notification family is documented under UL 464, UL 1638, UL 1971, and applicable CAN/ULC signaling standards, along with CSFM and FM approvals. The device measures approximately 7.8 inches high, 5.75 inches wide, and 1.6 inches deep and weighs approximately 1.7 pounds. Its combination of low-current LED technology, selectable audible signaling, synchronized strobe operation, and outdoor-rated construction provides a versatile fire alarm notification solution for demanding commercial environments.
