Alarm
Principle
An alarm is issued by the system if an automatic detector has responded or a manual call point
was actuated.
The alarm is indicated by:
optical signals
− blinking of the red LED alarm bar on the control console
− alarm message on the text display
acoustic signals
− buzzer of the control console
− attached signal horns
As described in the SPECIAL Alarm Concept, the operating personnel is involved into the alarm
scheme only if the system is in “manned” mode. In all other cases, i. e. SPECIAL Alarm Concept
is not activated (used) or the system operates in “unmanned” mode, the alarm is transmitted
immediately to the fire brigade.
i
During alarm other states such as faults etc. are not shown at the display. However, it is
possible to make them visible via the menu “Info polling” (For details page 49).
