7.3 Connecting external alarm indicators

Building Technologies
Fire Safety
The mimic display driver is a parallel LED indication for the system-wide signaling
of events and is connected to the C-NET detector line.
The LED are built in a ground plan panel.
Some C-NET devices have an output where normally an ↑ external alarm indicator
is connected. The output can, however, also be used for any other controls. The
output for the external alarm indicator is controlled by the fire control panel and is
freely configurable.
Depending on the configuration, the output is activated for the external alarm
indicator if the following is true:
The connected detector is in ↑ danger level 2 or 3 (together with the internal
alarm indicator).
The assigned ↑ zone has triggered an alarm or ↑ pre-alarm.
The assigned control is active.
The following ↑ external alarm indicators are available:
DJ119x/FDAI9x – external alarm indicators that must be connected to the
detector to be displayed.
FDCAI221 – addressable alarm indicator that can be assigned to any cause
using a control.
