5.14 Direct Display of Failures
The keypad buzzer is immediately activated in the presence of a failure event, and the cause of the failure
is displayed on the display. All the failure type programmed outputs are also activated. The displaying of
failure events on both the LCD and LED are of maximum priority. Consequently, such indications will cover
(conceal) any default messages (e.g., date and time).
If there is a concurrence of failures, all the causes will be repeatedly displayed in rotation. Failure
messages will disappear only if the causes that triggered them are eliminated. The same is true for the
buzzer warning.The buzzer may be turned off, even during a failure, by pressing the ‘F’ key.
The following table contains all the possible messages that can be displayed on the two different keypads.
The characters on keypads with led display are displayed with flashing.

MANAGEMENT OF NETWORK ABSENCE/RESTORATION
The system provides for 5 network control points. One in the unit (intrinsic), and another for each expansion When the
auxiliary input is programmed for control, the absence of network on one or more control points is indicated as a failure,
and recorded in the event log, only at the end of the 1 hour timeout. The same holds true for the restoration of network,
when there is a 1/2 hour timeout. The network is considered to be present only if present at all control points.
The event is displayed clearly on the LCD display, and the message disappears as soon as soon as the cause that
triggered has been eliminated.
