7 Alarm verification concept (AVC)
The ↑ 'Alarm Verification Concept' serves the purpose of delayed alarm
transmission and takes into account the interaction of the operating personnel in
the alarming sequence.
Operating personnel are able to examine the indicated fire location in the event of
a fire alarm. In the event of a ↑ false alarm or minor incident the intervention of the
fire brigade can be avoided.

1 'Area'
The 'Area' receives 'Pre-ALARMS' or 'ALARMS' from 'Zones'. Alarm verification
takes place at 'Area' level.
Configuration for 'Pre-ALARMS' and 'ALARMS' is not related within 'AVC'. The type
of verification and alarming can be separately configured for the 'Manned
operation' and 'Unmanned operation' operation modes.
'ALARMS' of 'Manual zones' and 'Automatic zones' 'Zones' as well as 'Degraded
FIRE ALARM' can be configured differently.
