Detector line (addressable)
Line technology in which the connected
participants, e.g. fire detectors, couplers, input
or output modules, are each given their own
address (individual display and operation, with
identification of the individual detectors).
Detector line (collective)
Line technology in which the connected
detectors form a common (collective) address
(common display and operation, without
identification of the individual detectors).
DIL switch
Dual in line for setting e.g. the addressing and
display type of response indicators.
Display sensitivity
Sensitivity level at which the unit starts
detecting smoke particles (level 1). It is
represented by means of a bar graph. See also
"Response sensitivity"
Disturbance alarm
Message that there is a deviation from a target
value in the fire alarm centre.
Disturbance variable
All exogenous variables which impair the
intended function of a fire alarm system.
Dual detection dependency
Measure for the verification of alarm statuses.
The fire alarm is only triggered after the
response of two detectors or multiple response
of one detector. With the response of the first
detector, both an internal alarm and a control
function can be triggered.
FDU
See "Fire detection unit"
Fire alarm system
Hazard alarm systems which serve people as a
direct call for help in case of fire hazards and/
or to detect and report fires at an early stage.
fire detection control panel
See "Fire detector control panel"
Fire detector
Part of a fire detection system that monitors a
suitable physical parameter continuously or at
successive time intervals. The parameter is
used to detect a fire in the monitoring area.
See also "Fire detector (automatic)" and "Fire
detector (non-automatic)".
Fire detector (automatic)
Detectors that detect and evaluate physical
parameters used to create hazard alarms, e.g.
point detectors, multi-point detectors, linear
detectors; see also "Aspirating smoke
detector".
Fire detector (non-automatic)
Detectors that must be operated directly or
indirectly by persons.
