In order to prevent unintentional activation of the alarm horn, releasing element
(actuator) and fire controls can be disabled in exceptional cases. Together with the
alarm horn, also the releasing element is disabled.
Disabled alarm horns and fire controls are not activated in the event of an
WARNING
alarm! Therefore, re-enable disabled alarm horns and fire controls again as
soon as normal conditions prevail!
Here's how to proceed, in order to disable the alarm horn, the releasing element
(actuator) and the fire controls:
1. Enable "Access level 2".
The LED "Operating access" lights up.
2. Press the "Disable/Enable" key ("Horn/Actuator"/"Fire control") until the desired
disabling is displayed. After disabling, you can proceed with the desired work,
without the alarm horn/actuator and the controls being activated.
The first pressing disables the alarm horn and the actuator:
–
The yellow LEDs "Horn/Actuator"/"Disabled" light up.
The second pressing disables the fire control:
–
The yellow LEDs "Fire control"/"Disabled" light up.
The third pressing disables the alarm horn, the actuator and the fire control:
–
The yellow LEDs "Horn/Actuator"/"Fire control"/"Disabled" light up.
The fourth pressing enables the alarm horn, the actuator and the fire control:
–
The yellow LEDs "Horn/Actuator"/"Fire control"/"Disabled" are no longer lit.
3. The system is again in normal operation.
