The Ahuja UHC-25XT is a 25W RMS weather-proof horn speaker engineered specifically for 100V distributed sound reinforcement, emergency notification, and high-intelligibility voice paging in demanding industrial and commercial environments. Built with an IP66-rated UV-protected ABS housing and a multi-tap line matching transformer, it provides reliable audio projection across large zones and extended cable infrastructures.
Industrial Plant Floors and High-Ambient-Noise Facilities
Manufacturing facilities, processing units, and heavy industrial workshops require paging horns that overcome high background acoustic noise. Operating with a frequency response of 250 Hz to 10,000 Hz—the critical spectrum for speech intelligibility—the UHC-25XT generates a maximum sound pressure level of 122 dB at 25W/1m (and 108 dB at 1W/1m, 1kHz). The driver assembly incorporates a voice coil precision-wound on an aluminium bobbin to ensure effective heat dissipation during continuous plant broadcasts and shift-change signaling.
Perimeter Security, Fence Lines, and Gatehouse Paging
Outdoor boundary monitoring and perimeter security systems demand hardware that withstands continuous environmental exposure. Certified with an IP66 ingress protection rating against dust ingress and high-pressure water jets, the UHC-25XT is fully sealed against moisture intrusion. Its acoustic bell, reflector, and rear cover are moulded from UV-protected ABS plastic to resist degradation from solar radiation. External mounting hardware uses corrosion-resistant stainless steel bolts, while the integrated heavy-duty metal bracket rotates through 270 degrees, allowing security contractors to precisely aim paging audio along property boundaries, gates, and access roads.
Long-Distance Distributed Audio and Facility-Wide 100V Lines
In large-scale industrial complexes, logistics yards, and commercial premises, running low-impedance speaker lines results in substantial voltage drops and cable power loss. The UHC-25XT integrates an internal 100V line matching transformer designed for distributed high-voltage transmission over long wire distances. Installers can easily calibrate individual zone loudness via an external rotary switch located on the rear of the sealed assembly without opening the enclosure, selecting between 25W, 20W, 15W, 10W, and 5W power taps (corresponding to 400Ω, 500Ω, 670Ω, 1kΩ, and 2kΩ impedances).
Transport Hubs, Logistics Yards, and Sports Grounds
Outdoor transport hubs, rail platforms, truck terminals, and sports facilities require wide-dispersion sound projection across open grounds. Measuring ø274 mm in diameter by 310 mm in length with a weight of 2.34 kg, the horn combines physical robustness with acoustic efficiency. It includes a factory-fitted 0.6 m (2 ft) 2-core sheathed speaker cable anchored via a water-tight, tug-proof cable gland, protecting cable entry points from strain and moisture during installation on exterior structural poles, masts, and warehouse gantries complying with EN 60065 Low Voltage standards.
