Use the SYSTEM RESET key to reset the control panel. When pressed, the control panel does the
following:

• Sends a “System Reset” message to the History buffer, and installed printers, CRT-2 terminals,
and terminal mode LCD-80s

If any alarm or trouble exists after you press the
SYSTEM RESET key, all NACs, control outputs, and
panel audio and visual indicators will reactivate.
Note: Trouble conditions will not clear and re-report upon RESET.
Note: If Local Control is set to “NO”, the FACP will not respond to SYSTEM
RESET.

LAMP TEST key is held for longer than five
seconds, the LCD will display the Software Revisions.
