BSC4 Video Controller Tests
When the system is idle (no calls in progress) pressing the „Test‟ button activates the
„Audio On, „Status‟ and one of the „Select n‟ LED‟s for 3S. If the system is not idle (Version
2 only) pressing the „Test‟ button will cause a system wide reset.
There are 4 green LED‟s which indicate power to the individual phones, on board fuses will
operate if a short exists.
The BSC4 also has 4 „Phone‟ test buttons which can be used to verify the „data‟
connection to the apartment station
. Pressing the „Test Phone n‟ button should cause the
apartment station and extensions, if any, to ring and the associate
d „Select n‟ Led to light.
Touching
pickup
or touching
view
will cause the „Audio On‟ and „Select n‟ LED‟s to light.
There will be no audio as no door panel is active. The display on the apartment station will
light up to grey or blue unless the video camera is directly wired to the BSC4 input.
Touching
pickup
again will cause all the LED‟s to extinguish. Touching the
lock
symbol
instead will cause the „Status‟ LED to light and after 3S all the LED‟s will go off.
If this sequence works repeatedly then the A and B data connections are probably OK.
and the +28V and 0V must also be OK. The test also shows that the BSC4 software is
running and diagnostics can now focus on the door controller to video controller wiring.
If it fails an apartment station can be connected locally with a short cable to eliminate the
cable being faulty.
