Operation:
• Basic Operation:
The simplest application of the LB-5A is when configured as a basic 5
message store which is triggered by remote switches (contact closures).
It is assumed that the section ‘Installation Procedure’ has been followed and the
unit is ready to be wired. A single pole switch will be required for each message that
is to be played and they need to be connected to the appropriate contacts on the
circuit board (SW1 to SW5). The gauge and type of wire is not critical but it must
be suitable for the environment in which it is to be used i.e. you should follow good
wiring practice and conform to any local or legislative regulations. Because in this
configuration only the five audio files in the message bank are being used (i.e. the
other banks aren’t required) a shorting link should be placed across the ‘Message
Select’ terminals on the circuit board. (If the other banks were to be used this link
would need to be replaced by a switching arrangement as described in the ‘Full
Operation’ section on page 10).
The audio output can then be connected to an amplifier using the appropriate
connections, which can be either the stereo phono sockets or the balanced mono
terminals. For more information about which of these outputs to use and appropriate
wiring, please see the section ‘Audio Outputs’ on page 22.
The USB memory stick with the required messages should now be fitted into its
socket on the main circuit board. For details about how to load audio files onto the
memory stick, please refer to the section ‘Loading audio files onto the memory stick’.
If the final messages are not available during the installation of the unit the system
can be tested using the supplied memory stick on page 20, which has been pre-
loaded with test messages, alarms and chimes in all of the fifteen positions, plus
some sample background music.
Finally, the plug top power supply should be connected to the unit by means of
the DC power socket located at the top left of the circuit board. Power can now be
applied to the unit by switching on the power supply at the mains outlet, and after a
brief setting up period of approximately 30 seconds, indicated by LED activity on the
circuit board and the memory stick, the unit is ready for use.
A diagram showing the configuration described above is shown overleaf.
