Alarm triggering and alarm output

The alarm functions can be triggered only in the primed state. A non-blocked alarm input triggers an alarm in the primed state with an active signal. The alarm-triggering input then remains blocked for further alarm triggering until it returns to the inactive state. Then, following expiry of the inactive period of 10 seconds, it is again included in the alarm evaluation, provided that it was inactive for the entire inactive period. In a priming cycle, the inputs Passenger compartment monitor,...
