Glossary
Normal operation
The fire detection installation is supplied with
mains voltage.
Parameter set
Defined detector behavior, e.g. in terms of
sensitivity, resistance to deceptive phenomena,
response time. Detectors can be operated with
different parameter sets.
Physical channel
Depiction of a device's physical function in the
hardware tree. The physical channel is always
the bottom level in the hardware tree.
PMI
The arrangement of operating and display
elements on a fire control panel or on a fire
terminal. Includes the LEDs, buttons, the display,
and the operation options such as the key
switch, fire brigade control and display (FBA),
and the EVAC NL Person Machine Interface.
Pre-alarm
Stage before an alarm for information early on,
should an event occur.
Pre-configuration
A sub-configuration of the hardware tree,
detection tree, and control tree created before
commissioning the fire detection installation.
Remote transmission
Remote transmission.
Router station
Participant in the SAFEDLINK sub-net for the
connection between the SAFEDLINK sub-net
and the Ethernet sub-net (FCnet/C-WEB/LAN)
via the Ethernet switch (modular) FN2012-A1.
RT
The abbreviation for remote transmission.
RT
The abbreviation for 'remote transmission'.
SAFEDLINK
Physical network of an FS20 / FS720 fire
detection system with the network module
(SAFEDLINK) and the network cable.
SAFEDLINK station
Participants in the SAFEDLINK sub-net with
local connection for the PC.

Building Technologies
Fire Safety
Section
Level in detection tree of the fire detection
system. The section is assigned to the area. It is
used for combining zones.
Single-detector dependency
With single-detector dependency, the alarm
decision depends on the danger level of one
detector. The first detector in the zone which
detects the corresponding danger level, triggers
the fire alarm.
Site
Depiction of fire detection installation: The top
level in the figure showing the installed system.
Combines hardware tree, detection tree, and
control tree.
Standalone station
Standalone station with local connection for the
PC.
Station
Unit for system control. Fire control panel or fire
terminal.
System bus
Loop-shaped, redundant networking by means
of FCnet / C-WEB / SAFEDLINK.
Technical message
Events (e.g., from third-party systems) evaluated
via sensors or contacts which are forwarded to
the fire control panel.
Test activation
Activation of fire detectors in the detector test or
effects in the control test.
Universal control group
Level in control tree of the fire detection system.
The fire control group contains the fire controls.
Unmanned
Switching status of the alarm organization, if
operating personnel are not present and cannot
intervene should an event arise (alarm, fault).
Visibility
Defines which part of a site is visible and can be
operated on a station.
Zone
Level in the detection tree. The zone has at least
one fire detector. The decision on alarm is made
at zone level. The zone is assigned to a section
or an area.
