Valcom SX15-T-GY 15-Watt Paging Horn
Overview
The Valcom SX15-T-GY is a 15-watt paging horn designed to deliver high-efficiency voice paging, emergency alerts, and audible signaling across indoor and outdoor installations. Part of the SX-Series paging horn lineup, the SX15-T-GY (often searched as SX15 T GY) generates clear, high-quality audio output suitable for industrial facilities, warehouses, parking lots, and similar demanding environments. The gray finish and wall/rack mounting options enable flexible deployment in both visible and discrete configurations.
Key Features
- 15-Watt Output: Delivers robust audio power for coverage across large interior and exterior spaces
- Multi-Voltage Support: Compatible with 25V, 70V, and 100V distributed audio systems, allowing integration into existing paging infrastructure without additional impedance matching
- High-Efficiency Design: SX-Series architecture optimizes acoustic performance and intelligibility for voice announcements and emergency alerts
- Dual Mount Configuration: Wall or rack mounting enables deployment flexibility in control rooms, electrical closets, or on-wall installation at coverage points
- Indoor/Outdoor Rated: Suitable for industrial facilities, warehouses, parking lots, loading docks, and outdoor perimeter applications
- Gray Finish: Professional appearance compatible with industrial and commercial aesthetics
Integration & Compatibility
The SX15-T-GY integrates directly into existing 25V, 70V, or 100V paging systems without requiring impedance conversion or additional amplification. This compatibility makes the horn suitable for retrofit projects in facilities already operating distributed audio infrastructure. The unit supports connection to standard paging controllers, VoIP endpoints with analog paging cards, and emergency alerting systems that output audio at these voltage levels.
Installation requires standard speaker wire terminated to the horn's input connections. Voltage selection is field-configurable, allowing a single SKU to serve multiple system architectures. This flexibility simplifies procurement and reduces spare parts inventory for integrators managing diverse customer installations.
Deployment Considerations
For indoor applications such as factories, warehouses, and office buildings, wall mounting near the intended coverage area provides direct sound projection. Rack mounting in equipment rooms connects to remote coverage points via speaker runs. Outdoor parking lots and perimeter applications benefit from the horn's 15-watt output and weather-resistant construction, though installers should verify environmental exposure ratings for specific climate conditions.
The SX15-T-GY delivers audible emergency alerts and voice announcements with clarity suitable for industrial noisy environments. Positioning multiple units in large spaces ensures uniform coverage and message intelligibility, critical for life safety announcements and facility-wide coordination during events or emergencies.

I've specified the Valcom SX15-T-GY in several warehouse and industrial facility upgrades over the past two years. This 15-watt horn offers reliable, efficient audio distribution for facilities already operating multi-voltage paging systems. The SX15-T-GY's compatibility across 25V, 70V, and 100V eliminates the need for custom impedance matching, which simplifies both design and installation.
Technical Highlights:
- Power Output: 15-watt delivery ensures intelligible voice announcements across large industrial and outdoor spaces without requiring parallel speaker arrays in most deployments
- Voltage Flexibility: Field-configurable 25V, 70V, 100V operation means one SKU covers multiple system architectures, reducing design complexity and inventory
- Mounting Options: Both wall and rack configurations support control room installations and distributed on-wall coverage points
Deployment Considerations:
- For large facilities exceeding typical single-horn coverage, plan multiple units with speaker runs from the paging controller. Test audio levels and intelligibility in the actual environment before final commissioning.
- Verify outdoor mounting compatibility with local weather exposure. In high-humidity or corrosive environments, confirm that the gray finish and enclosure materials meet expected service life.
- During system design, confirm voltage matching between the paging source (controller, VoIP gateway card) and the horn's input. Voltage mismatch will result in distortion or no output.
The SX15-T-GY remains a cost-effective, straightforward choice for integrators building or upgrading distributed paging systems in industrial, warehouse, and facility-wide alert applications. Its efficiency and multi-voltage support reduce project complexity without sacrificing audio quality.
