Valcom SX15-TM Marine Pa Horn 15W 25/70/100V

Product Description

The VALCOM SX15-TM is a 15-watt marine-grade public address horn designed for use on constant-voltage PA distribution systems operating at 25, 70, or 100 volts. Built to withstand the harsh conditions found in marine environments, this horn delivers clear, projected audio coverage in areas where corrosion resistance and durability are critical. Licensed electricians and marine systems integrators install this type of device as part of distributed audio, paging, or emergency notification systems. The multi-voltage compatibility makes it flexible for a range of existing PA system architectures without requiring additional transformers.

The SX15-TM is suited for marine vessels, docks, boatyards, and other wet or corrosive environments where a standard commercial PA horn would not hold up. It functions within 25V, 70V, and 100V constant-voltage systems, making it appropriate for both smaller vessel installations and larger commercial marine paging setups. This horn is sold as a single unit and is a direct fit into PA horn circuits that require a rugged, weather-resistant audio device.

Key Features

• 15-watt power handling for strong audio projection in open or noisy environments
• Multi-voltage operation at 25, 70, and 100 volts for compatibility with common constant-voltage PA systems
• Marine-grade construction rated for wet, humid, and corrosive environments
• Single-unit packaging for straightforward procurement and replacement

Compatibility

Designed for use with 25V, 70V, and 100V constant-voltage public address systems in marine and other demanding outdoor or wet-environment applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified marine systems technician familiar with constant-voltage PA wiring practices and applicable electrical codes. De-energize the PA amplifier and confirm the system is at zero voltage before making any wiring connections. Ensure the horn is mounted in an orientation that prevents water pooling in the enclosure, and verify that all conduit or cable entries are sealed appropriately for the marine environment.
