Effect
An impact caused by a control, e.g., activation of
a hardware output or a command.
Ethernet station
Participants in the Ethernet sub-net without local
connection for the PC.
Extended networking
Connection of several SAFEDLINK networks.
External alarm indicator
Optical element for displaying the fire location,
which is at some distance from the detector. It is
normally mounted in the room at the point where
the corresponding detector is accessible.
Extinguishing control
Control which controls a connected extinguishing
system and evaluates and displays its states.
False alarm
Alarm not triggered by a danger.
Fire control
Control which is activated in the event of a fire
alarm.
Floor repeater display
A display device without operating elements.
Floor repeater terminal
A display device with operating elements for
acknowledging and resetting alarms and faults.
GAP
Abbreviation for 'Global Access Point'.
Participant in the Ethernet sub-net for the
connection between the Ethernet sub-net and a
management station (BACnet client) and / or for
remote access with the PC. If there is a
secondary GAP, the GAP becomes the main
GAP. Can be operated as a DHCP server in the
Ethernet sub-net.
Global alarming
Global alarming equipment (e.g., remote
transmission) is actuated and external
intervention forces (e.g., the fire brigade) are
alerted.
Hardware tree
Depiction of the hardware of a fire detection
installation.
Building Technologies
Fire Safety
IC
Abbreviation for 'intervention concept'
Intervention concept
Concept with two independent verifications:
Attendance check for quick intervention on-site
and intervention check for servicing measures.
Isolation
Status of one part of the fire detection
installation, which suppresses the evaluation of
all signals.
License key
Hardware modules for activating functions.
Local alarming
Local alarming equipment (e.g. acoustic or
optical) is actuated in order to call up
intervention personnel and to alert people of a
possible fire hazard.
Logical channel
Depiction of a logical device function in the
detection or control tree. The logical channel is
always the bottom level in the structure tree.
Management station
A superordinate system for monitoring and
operating safety-related sites and buildings, e.g.,
fire, intrusion, access, heating, ventilation.
Manned
Switching status of the alarm organization, if
operating personnel are present and can
intervene should an event arise (alarm, fault).
Minor incident
Alarm situation which the operating personnel
can handle themselves and does not, therefore,
trigger global alarming.
Multi-detector dependency
When using multi-detector dependency, the
danger levels of several detectors are included
in the alarm decision. Measures such as
alarming or closing the fire doors are only
initiated when the defined dependencies occur
(e.g., two detectors detect danger level 3).
Network tree
Figure of the network in a fire detection
installation.
