Additional Functions:
• Repeat Interval Timer:
The LB-5A is equipped with an adjustable interval timer which operates on the
second file in Group 1. When activated, the timer causes the file to be played at a
preset interval of every one, two or three minutes. Activation of the timer and interval
period is by setting the internal jumpers J8 and J9 as per the table below.

Note: SW2 must remain activated
Please note:
• The activation terminals (SW2) must remain shorted by means of a contact closure
or shorting link for the timer to operate.
• The corresponding files in banks 2 and 3 (Tone2.mp3 and Chim2.mpg) will be
unavailable while the timer is in operation.
• LB-5A Looping and One-shot operation:
The LB-5A supports 'looping' (i.e. an audio file will be played continuously) as long
as the contact closure triggering the playing is maintained across its corresponding
terminals. When the contact closure is removed the file will be played to the end and
then stop as normal.
Please note:
• This facility is only available within banks 1 and 2 (messages and tones)
• Any files of lower priority will be unavailable during this looping operation
• The looping file will be overridden by the playing of a file of higher priority
Bank 3 (chimes) doesn't support looping and is only 'one-shot' (i.e. the file will only
be played once, even if the activating contact closure is maintained). To play the file
again the contact closure must first be broken and then re-made.
