Valcom SX30-T-GY 30-Watt Paging Horn
The Valcom SX30-T-GY is a high-efficiency paging horn designed to deliver clear, intelligible voice announcements and emergency alerts across industrial facilities, warehouses, parking lots, stadiums, and outdoor environments. The SX30-T-GY (often searched as SX30 T GY) combines robust construction with switchable voltage configuration to integrate seamlessly into existing distributed audio and emergency notification systems.
Overview
The SX30-T-GY delivers 30 watts of audio output with voltage flexibility — switchable between 25V, 70V, and 100V tapped configurations — enabling deployment in both dedicated and shared audio infrastructure. The gray finish provides subtle visual integration while meeting durability requirements for industrial and outdoor mounting. This horn is engineered for installations requiring high sound pressure levels without the complexity of external amplification or impedance matching hardware.
Key Features
- 30-Watt Output: High-efficiency horn generates sufficient sound pressure for facility-wide coverage and emergency alerting
- Switchable Voltage Modes: 25V, 70V, and 100V configurable operation supports both dedicated and shared audio bus installations
- Dual Mount Capability: Wall and rack mounting options provide flexible deployment in control rooms, mechanical spaces, and exterior installations
- SX-Series Design: Part of Valcom's proven SX-Series paging horns, engineered for high-quality voice reproduction and emergency alerts
- Indoor/Outdoor Rated: Suitable for industrial facilities, warehouses, parking structures, stadiums, and outdoor areas requiring durable paging coverage
- Gray Powder-Coat Finish: Corrosion-resistant finish extends service life in mixed-use environments
Integration & Compatibility
The SX30-T-GY integrates into distributed audio systems via standard 70V or 100V speaker bus architecture, compatible with legacy voice evacuation systems, paging controllers, and emergency notification platforms. The switchable voltage taps accommodate both retrofit scenarios (where legacy 25V systems are in place) and modern multi-zone installations using 70V or 100V distribution. No external transformers or impedance-matching equipment are required when used on properly configured audio buses.
Deployment Environments
The SX30-T-GY is rated for both indoor and outdoor installations. Wall mounting is standard for exposed or protected outdoor mounting on building exteriors, poles, or overhangs. Rack mounting supports installation in distributed amplifier cabinets, equipment rooms, or telecommunications closets where horns are centrally located and fed via long cable runs. The gray finish resists UV degradation and corrosion in outdoor exposures.

I have specified the Valcom SX30-T-GY in large-footprint facility audio and emergency notification projects where distributed paging horns must cover multiple zones on a shared bus. The 30-watt output and switchable voltage configuration eliminate the need for secondary transformers, reducing bill-of-materials complexity and troubleshooting overhead during commissioning.
Technical Highlights:
- 30-Watt Efficiency: Delivers high sound pressure levels without requiring oversized amplifiers or dedicated power supplies
- Multi-Voltage Support: Switch between 25V, 70V, and 100V allows retrofit compatibility with legacy systems and migration to higher-voltage buses without hardware replacement
- Dual Mounting: Wall and rack options adapt to facility architecture, whether exterior-mounted on structures or rack-mounted in centralized equipment rooms
Deployment Considerations:
- Verify the audio bus voltage in your existing installation before configuring the SX30-T-GY's internal tap switches. Incorrect voltage selection will result in under- or over-driven operation and potential damage
- In outdoor applications, ensure the mounting surface and hardware are rated for UV and corrosion resistance, particularly in coastal or high-humidity environments
- Test intelligibility in the actual deployment environment during commissioning. Sound reflection, background noise, and distance from the horn may require additional speakers or repositioning to meet emergency notification performance standards
The SX30-T-GY represents a straightforward, field-proven solution for facility-scale paging and emergency alert distribution. It is well-suited to security integrators managing system expansion, retrofit projects, or new multi-zone emergency notification deployments.
