In certain situations (e.g. maintenance work) it is reasonable to disable parts of the
system. If a system part is disabled (isolated), then the LED "Disabled" is lit
continuously.
Disabled system parts can under certain circumstances prevent the correct
acquisition or processing of alarms or faults as well as activation of
WARNING
extinguishing. Therefore, re-enable all disabled system parts as soon as normal
conditions prevail!
In order to prevent unintentional alarm messages or activation of extinguishing, in
exceptional cases detector zones must be isolated from the system. The instances
wherein a detector zone should be disabled depend on the detectors used and the
fault dimensions (e.g. smoke or dust).
Switched-off detector zones prevent activation of extinguishing!
WARNING
Therefore, enable all switched-off system parts again, as soon as normal
conditions prevail!
Here's how to disable a detector zone:
1. Enable "Access level 2".
The LED "Operating access" lights up.
2. Press the key "ZONES Disable/Enable" until the yellow LED is lit at the desired
detector zone. After disabling, you can perform the required work on the detector
zone, without the risk of alarm or fault.
The first pressing disables detector zone 1:
–
The yellow LEDs "Detector Zone 1"/"Disabled"/"Manual only" light up.
The second pressing disables detector zone 2:
–
The yellow LEDs "Detector Zone 2"/"Disabled"/"Manual only" light up.
The third pressing disables detector zones 1 and 2:
–
The yellow LEDs "Detector Zone 1 and 2"/"Disabled"/"Manual only" light up.
The fourth pressing disables detector zone 3:
–
The yellow LEDs "Detector Zone 3"/"Disabled" light up.
The yellow LED "Manual only" is no longer lit (depending on programming).
The fifth pressing disables detector zone 4:
–
The yellow LEDs "Manual Release (Zone 4)"/"Disabled" light up.
The sixth pressing disables all detector zones:
–
The yellow LEDs "Zones 1 to 4"/"Disabled"/"Autom. & Man. blocked" light
up.
The seventh pressing re-enables all detector zones:
–
The yellow LEDs "Zones 1 to 4"/"Disabled"/"Autom. & Man. blocked" are no
longer lit.
3. The system is again in normal operation.
