The alarm is signalled to the unit (1) from a connected alarm, unit if the current path through the alarm unit is closed or broken, whereby monitoring of the closing or breaking function can be selectively adjusted in the unit. In the unit (1) is located a calculating circuit (19) with inputs (15), to which the single conduits from the alarm units are connected, and manual feed-in components (11,19) coupled to the calculating circuit (19). The calculating circuit receives adjustment information from the manual feed-in components for each separate input (15) dependent upon whether the input functions with a closing or breaking function in a connected alarm unit and/or give adjustment information a delay time, which will move after the time point when the alarm monitor establishes that an alarm unit connected to the special input (15) has given an alarm. |
