Fire Safety
↑ 'Area'
● 'Area' typically corresponds to a building.
● 'Area' combines ↑ 'Sections' which are subject to the same 'Manned
operation'/'Unmanned operation' operation mode.
● 'Area' actuates the ↑ alarming equipment (acoustic and ↑ optical alarm devices
as well as remote transmission).
● 'Area' is assigned the following functions:
– 'Manned operation'/'Unmanned operation' operation mode
– Switching assigned 'Sections' on/↑ off
Several 'Areas' are possible per control panel:
● FC722, FC723, FC724: up to four 'Areas'
● FC726 up to eight 'Areas'
There is an 'Area' that groups together the functions of alarm verification (AVC),
e.g. collective alarms and degraded mode operation.
↑ 'Section'
● 'Section' combines 'Zones' to form logical units. Such a unit can be e.g. a floor
or a staircase.
● 'Section' is assigned the following function:
– Switching assigned 'Zones' on/↑ off
'Zone'
● 'Zone' generally combines the detectors in a room.
● 'Zone' evaluates the danger levels transmitted by the detectors. The configured
combination of different danger levels defines the conditions upon which an
'ALARM' is triggered.
● The following fire alarm zone types exist:
– 'Automatic zone'
– 'Manual zone'
– 'Technical zone'
– 'FSE zone'
– 'Flow switch zone' (sprinkler)
– 'Sub-system zone'
● The following extinguishing zone types exist:
– 'Sprinkler zone'
– 'XC10 zone'
'Channel'
The 'Channel' in ↑ 'Detection tree' represents the functionality of the inputs and
outputs of an C-NET device.
