DESCRIPTION
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).
* Note: For outdoor installation, it is recommended that they be installed under roofs, eaves, or in
other locations not directly exposed to rain or snow.
