Connected Control Units; Transmit Alarm From One Control Unit Kfc To Another - Velux KFX 210 Instructions Manual

Status and error indication
in control system
ERROR - BREAK-GLASS POINT
The printed circuit board monitors for defects in the cable to any break-
glass points that are connected.
If the cable to the connected break-glass point(s) is interrupted, the yel-
low light-emitting diode flashes on and off. If the cable is short-circuited,
the yellow light-emitting diode is on permanently.
The error is also indicated in the integrated break-glass point and pos-
sible additional break-glass points.
ERROR - TEMP. FUSE
The printed circuit board monitors the temperature in the control unit.
If the temperature in the control unit rises above 70 ˚C, the temperature
fuse on the printed circuit board is activated and all connected windows
open for smoke ventilation. The yellow light-emitting diode is on perma-
nently until the printed circuit board has been replaced. After replac-
ing the printed circuit board, the installation must be service tested
thoroughly to ensure that the system works correctly.
The error is also indicated in the integrated break-glass point and pos-
sible additional break-glass points.
ALARM - ACTIVE
The red light-emitting diode on the front of the control unit is on per-
manently when the smoke ventilation function has been activated (from
break-glass point, smoke detector or external fire alarm).
The alarm can be reset by pressing the button
this, the light-emitting diode on the printed circuit board and in all break-
glass points are turned off.

Connected control units

Transmit alarm from one KFC control unit to another
In installations with several connected control units, all smoke detectors
and additional break-glass points must be connected to control unit 1
only (see below). In the other control units, the glass plate on the front
face must be replaced by the blank lid provided. In case of an alarm, an
acoustic alarm sounds from all control units and all windows open.
Connection is established from the ALARM terminal in the principal con-
trol unit to the FACU terminal in the next control unit. If more than two
control units are linked, connect from the ALARM terminal in control
unit 2 to the FACU terminal in control unit 3 etc.
Note: In control unit 2 and possible additional control units, dip switch
no. 2 is set in position ON.
