Operational Description
To use the Remote Bell Ringer, the Operator will first select, via the
Rotary Switch, which of the Bell Circuits are to be made active.
Selected Circuits that are not configured as Bell Circuits in the Master
Controller will be ignored
y
The ‘OFF’ position may be used to de-activate all Bell Circuits
y
Positions ‘1’ to ‘8’ may be used to select a single Bell Circuit to be
made ‘Active’
y
The ‘ALL’ position may be used to activate all circuits configured
as Bell Circuits.
After setting the selected position of the Rotary Switch, the Operator
should press the ‘ENTER SELECTION’ Push-Button. This will ‘wake-
up’ the Microprocessor (indicated by a brief ‘flash’ of the indicators)
which will, in turn, read the Switches and transmit the appropriate
Command to the Master. It will wait for a reply from the Master, which
will indicate the Bell Circuits which are now Active, and display that
information on Lighting Indicators as confirmation to the Operator that
the Command has been accepted and executed by the Master. The lit
Indicators will remain active for 2 seconds after the button is released,
after which the unit will go back to ‘sleep mode’, to conserve power.
