MASTER/SLAVE Connections, Settings | TOA Electronics C-AL80(L)

8. MASTER/SLAVE CONNECTIONS

An entire system can have up to 256 Alarm/Remote inputs through master/slave connections (cascade connections) of up to 8 C-AL80 Units.

8.1 Unit Number Settings

Be sure to set the unit number when making master/slave connections.

Because each component is factory-preset to the unit number for individual use (same setting as the master unit), change the number when making a master/slave connection.

Note

Make sure that the Power switch is set to OFF when changing each switch setting. The system does not operate correctly if the change is made with the Power switch set to ON.

8.2. Master/Slave Terminal Connections

Connect the Master/Slave terminals of all C-AL80 units to be included in the master/slave connection in order of the unit number. Set the RS-485 Termination switch of the master unit and the last-connected slave unit (highest unit number) to ON, and those of other units to OFF. Set the Termination switch to OFF when using the unit individually. (Factory-preset position: OFF.)

Note

The system does not operate correctly when the unit number is not correctly set, when the unit numbers are duplicated or not consecutive or when the BS-485 Termination switch is not correctly set.

C-AL80(L), C-AL80(H) specifications

TOA Electronics is known for its high-quality audio equipment, and the C-AL80 models, specifically the C-AL80(H) and C-AL80(L), continue this tradition. Designed for a variety of applications, these compact and robust ceiling speakers are ideal for both commercial and residential installations.

One of the standout features of the C-AL80 series is their dual impedance capability. The C-AL80(H) is designed for 70V/100V constant voltage systems, making it perfect for larger audio installations requiring multiple speaker connectivity. In contrast, the C-AL80(L) offers standard low-impedance operation, allowing users to connect speakers to traditional amplifiers for flexibility in audio setups. This versatility means that both models can be incorporated into a wide range of environments, from schools and offices to shopping centers and homes.

The speakers feature an 8-inch cone woofer that provides excellent sound reproduction with deep low frequencies, while the 1-inch dome tweeter delivers clear and articulate high frequencies. This combination ensures a well-balanced audio experience, suitable for various sound sources, including music and spoken word applications. The optimized design of the speaker cabinet also helps reduce unwanted resonance, leading to a more accurate sound.

Another key feature of the C-AL80 series is their easy installation process. The speakers are equipped with a quick-mounting mechanism, which allows for swift and hassle-free setup. Their low-profile design ensures they blend seamlessly into any environment, making them aesthetically pleasing while maintaining high performance.

The C-AL80 models are also built to last, featuring durable materials and weather-resistant properties, making them suitable for both indoor and outdoor use. This durability is critical for installations in locations that may experience varying environmental conditions.

With a combination of advanced technologies, user-friendly features, and reliable construction, TOA Electronics C-AL80(H) and C-AL80(L) speakers are perfect for anyone seeking high-quality audio solutions. Whether for background music, announcements, or immersive sound experiences, these speakers deliver top-notch performance tailored to both professional and casual users. Their flexibility in impedance configuration and installation ease makes them a favorite among audio professionals and enthusiasts alike.
