Operation
Operation of the access panel is highly dependent on the attached system’s software configuration. The
software is factory-created and is subsequently downloaded to the system control unit via an external PC
at system start-up.
This access panel offers the following standard features in addition to the configurable options including a
handset for page and party functions, a vacuum fluorescent display (VFD) that shows the system status in
a text format, and a piezo alarm that may be activated to alert the operator of a change in system status.
Handset Communications
The handset is used for both page and party communications. Lifting the handset from the cradle creates
an off-hook condition. In a normal configuration, lifting the handset causes it to be connected to a party
line.
Vacuum Fluorescent Display (VFD) and Control
The VFD displays status messages from the system control unit in a text format. Typically, the push
buttons to the right of the VFD are configured for NEXT and PREVIOUS functions. Use the NEXT
push button to view each additional new message. The NEXT push button can be configured to flash
when a new message is available. Use the PREVIOUS to cycle backward in order to review old status
messages.
Piezo Alarm
The piezo alarm is an audible indicator. It is typically configured to sound when a new message is
available on the VFD. If configured as described above, press the NEXT push button to display each new
message. When the last available new message has been displayed, the piezo alarm turns off. The exact
details of the operation of the piezo alarm are configurable.
