Wiring Signal Devices to the Master Clock

Typically, signal devices (such as bells or lights) are wired to terminal block P3. If no secondary clocks are connected to terminal blocks P1 or P2, signal devices can also be wired to those blocks. See the figures below.

Zone 7A and 7B operate together, and 5A and 5B operate together. You can use either of these circuits for bells. All circuits should be fused or protected by a circuit breaker (10A maximum).
