Functions:
Signals on/off switch (3,4) – This input allows an external switch to be used to
control the signals on/off state. If either the internal (on the manual panel) or
external switches are in the 'on' position the signals are requested on. (switch
closed = signals on)
Cabinet Alarm LED Drive (5,6) – This output allows an external LED indicator to be
installed to indicate the cabinet alarm state. This output is current limited to 33mA
under short circuit conditions.
Door Switch (7,8) – This input allows an external switch to be used to connect a
cabinet door switch. (switch closed = door closed) If either this input or the standard
manual panel indicate door closed the controller door state will be closed.
