Special Modes
Signal Detection Mode
In this mode the three remote buttons are disabled (mode, source and restore). The recovery
time is automatically set to zero for both channels. All other functions operate as in normal
mode.
Force Main Mode
In this mode only the remote mode control input has any eect. When this control input
is active (low) the output is forced to Input 2 (MAIN input) regardless of whether audio
is present. The unit operates in auto mode and with input 2 as the MAIN input. All other
functions operate as in normal mode.
Emergency Program Override Mode
In this mode all alarm LEDS are illuminated whenever the main input is active. This is to
indicate that the emergency paging program is active on the MAIN input. When the paging
program goes silent, the unit will revert back to the AUX input and all the alarm LEDS will
switch o. All other functions operate as in normal mode.
Detection Disable/Enable Mode
In this mode the silence detection can be disabled and enabled remotely. The SCi “Detection
is” drop down box and the remote source button is used to switch between the two modes.
The “Detection is” drop down box toggles the state, while the remote source control (pin
14 on the remote connector) can only ENABLE the silence detection feature. Pin 10 on the
remote connector is used to DISABLE silence detection. When the unit powers up Silence
Detection is always enabled. The remote source select indicator (Pin 13 on the remote
connector) is enabled when Silence Detection is disabled. In this mode Input 1 is always the
MAIN input and Input 2 is always the AUX input. The AUX alarms are masked for both front
panel indicators and remote alarm relay, for as long as the MAIN input is present.
When Special Modes are selected, certain controls are disabled or altered:
Signal Detection Mode: Main Input and return mode selection is disabled. Recovery times
are set to zero.
Force Main Mode: Main Input and return mode selection is disabled.
Emergency Program Overide Mode: Main Input selection is disabled.
Detection Enabled/Disabled Mode: The Main Input selection label becomes “Detection Is”
and the options available change to “ENABLED” and “DISABLED”.
