A busy light would be used when more than one door panel is connected to
the system. The busy light will illuminate when a call is activated at any door
panel.
The Sentry 1 PCB incorporates four LED's which are used to indicate what
state the PCB is in. These LED's are labeled D10, D11, D12, D13. They
relate to the following functions :-
D10
:
When this is illuminated, the system is awaiting a call.
D11
:
When this is illuminated, the system is busy.
D12
:
When this is illuminated, the call is from door one.
D13
:
When this is illuminated, the call is from door two.
The Sentry 1 PCB includes a link option (JPR1) which when in position A, the
system will only allow one call to be activated at anyone time. The system
must time out before another call can be registered. When the link is in
position B the system will allow another button to be pressed with out waiting
for the system to time out. (The link should only be fitted in position B when
the system is being tested or being used as a one door system).
VIDEX run training courses for engineers who have not installed the sentry 1
system before.
