or a fault in the unit. The buzzer will be silenced when all
faults are acknowledged (in any c.i.e.) or with the push button "P2"
(Silence buzzer).
When a fault is displayed, the display back-light is turned on.
The fault messages will be displayed on the first row in the display.
A fire alarm has higher priority, i.e. it will be displayed instead of any
fault message.

ext. Presentation unit and in the c.i.e. respectively.
