TOA SC-630TU Paging Horn Speaker is a high-impedance speaker featuring a built-in 25 V /70 V transformer with external screwdriver-adjustable power taps. With a rated input of 30W, it provides intelligible voice paging and tone signaling for indoor and outdoor sound system applications. The speaker is certified to UL 1480 UUMW (Mass Notification System) and ULC-S541 standards and is fully weather-resistant for reliable operation in demanding environmental conditions. It is easily installed in wall, pole or ceiling-mount applications. The SC-630TU is also designed for intercom talk-back applications, enabling dual operation as both a microphone and a speaker.
It features a double re-entrant horn with compression driver for high sensitivity and a lightweight aluminum enclosure. The loud-speaker diaphragm is heat- and moisture-resistant to prevent deformation and extend operation. The SC-630TU is also IP65 standards compliant for dust and moisture resistance with a wide operating temperature range from -40°F to 151° F (-40°C to 66° C).
