Simplex Trouble Alarm

I am receiving a trouble alarm at work that I can’t explain to the client. It reads

ADMINISTRATION PIEZO
ANNUNCIATOR PIEZO

What is the model of the panel? It is usually on the front door and/or the dress panel.

Is that all that shows in the display or is there more? Please include everything the display shows.

We will try to help but need more information. That is something I never saw on any panel in over 40 years with Simplex.
