The TOA SC-630TU is a 30-watt, weather-resistant paging horn speaker designed to deliver clear voice announcements, paging messages, and alert tones in commercial, industrial, and outdoor environments. Featuring a high-efficiency double re-entrant horn design, the SC-630TU provides focused sound projection and excellent speech intelligibility for applications where announcements must be heard over background noise.
Built for demanding installations, the TOA SC-630TU features an IP65-rated enclosure, powder-coated exterior, and stainless steel mounting bracket and hardware. Its durable construction makes it suitable for outdoor paging systems, warehouses, loading docks, manufacturing facilities, parking areas, and other locations exposed to dust and moisture.
The SC-630TU is equipped with a built-in transformer and a rotary impedance selector for use with 25V and 70V distributed audio systems. This allows installers to match the speaker's power setting to the requirements of the paging amplifier and installation.
Designed for voice communication and signaling, the SC-630TU also incorporates a heat-resistant polyimide diaphragm and protective transformer housing for dependable performance in challenging environments.
With its combination of high speech clarity, rugged construction, and flexible installation options, the TOA SC-630TU is an excellent choice for professional paging and notification systems.

High-Intelligibility Paging for Noisy Environments
The TOA SC-630TU is engineered for installations where speech clarity is essential.
Its double re-entrant horn and compression driver design help project announcements across large or noisy spaces, making it suitable for warehouses, factories, loading docks, and outdoor facilities.
Unlike conventional background music speakers, the SC-630TU is optimized for voice announcements and signaling rather than full-range music reproduction.
This makes it especially useful for paging systems where employees, visitors, or building occupants need to hear instructions clearly.
25V and 70V Paging System Compatibility
The SC-630TU includes a built-in transformer that allows it to operate with compatible 25V or 70V distributed audio amplifiers.
Its rotary impedance selector provides convenient configuration during installation, allowing the speaker to be matched to the available amplifier power and the requirements of the paging system.
This flexibility makes the SC-630TU suitable for both new installations and upgrades to existing commercial paging systems.
For multi-speaker installations, the combined transformer tap wattage should remain within the amplifier's available output capacity, with appropriate system headroom.
IP65 Weather-Resistant Construction
Outdoor paging speakers must withstand environmental conditions that can damage conventional indoor loudspeakers.
The TOA SC-630TU features an IP65-rated design that provides protection against dust and water jets.
Its powder-coated exterior and stainless steel mounting hardware help resist corrosion, while the heat-resistant polyimide diaphragm supports dependable performance across a wide temperature range.
These features make the SC-630TU suitable for exposed commercial and industrial locations where durable paging equipment is required.
Emergency Notification and Talk-Back Applications
The TOA SC-630TU is designed for paging, voice announcements, and tone signaling applications.
Its listed safety characteristics make it suitable for consideration in applicable emergency communication and fire alarm signaling systems when installed according to the manufacturer's instructions and relevant system requirements.
The speaker can also support talk-back operation when connected to a compatible intercom system, allowing it to function as part of a two-way communication arrangement.
For life-safety applications, confirm the speaker's listing, amplifier compatibility, installation requirements, and applicable local codes before installation.
