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.
• Master/Slave Terminal Cable Type Use the supplied DIN plug and the twisted pair cable with plug for connection between the Master/Slave terminals. Refer to the figure shown below and note the correct polarity when making the connection. Pin No. 1 – Pin No. 1 Pin No. 3 – Pin No. 3 Control signal (positive) Control signal (negative) Do not connect pins Nos. 2, 4, and 5.
9. RACK MOUNTING When mounting the C-AL80 Unit in an equipment rack, remove 4 plastic feet on the bottom plate and attach an optional MB-23B mounting bracket.
