Chapter 10 - RB-SD1 Silence Detection Unit
10-8 Redbox User Handbook
This alarm state is continued until the RESTORE pin opens to the DIGITAL GROUND
pin. After this the unit will switch back to the main input when audio is present.
NOTE: When operating in manual mode, restoration of output from the main input is
only available via the front panel restore switch. All other functions operate as
normal.
Signal Detection Mode In this mode the three controls, source, remote source,
mode, remote mode, restore and remote restore have no effect.
The count in time for the signal detection is zero, i.e. as soon as signal is detected on
an input the relevant relay will switch. The relays operate the same as in normal
mode, i.e. when audio is detected on the main input, pin 1 on the remote connector
closes to pin 9. When audio is lost on the main input, pin 2 on the remote connector
closes to pin 9. All other functions operate as with normal mode.
To set the different modes
Apply power to the unit, and while the front panel ALARM LED is flashing, press and hold
the RESTORE button. The MAIN LEFT PROG, MAIN LEFT ALARM, MAIN RIGHT PROG and
MAIN RIGHT ALARM LED’s should now be flashing alternately. To select Normal Mode
release the RESTORE button while the MAIN LEFT PROG LED is on. To select the Remote
Stop Mode release the button while the MAIN LEFT ALARM LED is on. To select Remote
Alarm Set Mode release the button while the MAIN RIGHT PROG LED is on. To select Signal
Detection Mode release the button while the MAIN RIGHT ALARM LED is on.
After the button is released the unit will start working after five seconds. You only
have to do this once as the mode is stored in non-volatile memory and you will only
need to repeat this procedure if you wish to select a different mode. Each time the
unit is powered on; the selected mode is visible by checking which LED is:
MAIN LEFT PROG LED on = Normal Mode
MAIN LEFT ALARM LED on = Remote Stop Mode
MAIN RIGHT PROG LED on = Remote Alarm Set Mode
MAIN RIGHT ALARM LED on = Signal Detection Mode
