SCT Six-Circuit Time Signaling Option
The SCT option is used with the 6-circuit master clocks and the Bogen TZMA Time Zone Relay module, to provide
automatic distribution of class change signals. Class change signal interrupts programming only at those speakers
programmed, via the TZMA, to receive the signal. Requires a dedicated time signaling amplifier, a dry contact clo-
sure for each circuit plus a common closure. Refer to Figure 4.
