WARNING
Danger due to unwanted blocking!
The connection of door contact switches to connection "5" and at the same time to
connection "13" causes the system to be blocked even when the doors are closed.
● Connect door contact switches only to connection "5"
or
to connection "13".
L
CAUTION
Unwanted release due to absent blocking!
If no door contact switches are used, the system is not blocked when the door is
opened. The system can however be released in the event of detection.
● If there are no door contact switches, inform all persons who are working on
the control cabinet of a possible release of the system if the door is open.
L
CAUTION
Danger to life if system is not operational!
Fire messages from the fire detectors and the manual call point which occur during
the state
„Extinguishing system blocked”
(= blocking of the extinguishing system),
generate the state and the message
„Extinguishing system activated”
. In blocked
state, this does not however lead to extinguishing.
● Start up the system again as quickly as possible (e.g. close the door(s) and
keep them closed).
L
CAUTION
Danger of injury due to escaping extinguishing agent!
If, when the system is blocked (display
„Extinguishing system blocked”
), a fire
alarm is released and blocking is removed when there is an alarm by, for example,
closing the door, the extinguishing process is released one second after blocking is
removed.
● Do not stop blocking the system until there are no red LEDs lit up and there is
no fire alarm shown in the display.
