9 Restart
The AA unit will restart :

When the unit is powered up

If the jumper "JP1" is shunted momentarily

After address setting (i.e. "P2" is pressed).

If the contact with the Control unit is OK again after:
"No contact with Control unit".
During the restart the LCD will display the following (no back-light):
"Checking program memory…"
followed by (very quickly)
"Program memory OK."
followed by
"SSD memory OK."
All LEDs will be turned “ON” during the restart.
If there is a program memory fault, a fault message will be shown in the
display:
"Memory fault in program area (n)"
(n=1 or 2).
The
AA unit will not work.
A fault message will also be shown in the C.I.E.:
In system FT512:
"FAULT: Comm, AAU xx, 1587 board x, CU xx".
In system FT128:
"FAULT: No reply AAU x".
In system FT1020G3:
"FAULT: No reply, alert annunciation unit ##, control unit ##"
If there is an SSD (Site Specific Data) memory fault or no SSD downloaded,
there will be a fault message in the display:
"SSD memory fault"
The AA unit will work since the alarm texts will be sent out from the C.I.E.
