Technical Term Definition
A
Aerosol
Also: smoke aerosol
An aerosol is a floating particle in the microscopic
or submicroscopic particle size range. It consist of
unburned parts of the fire load, intermediate
products of the oxidation and finely divided carbon
(soot).
Air flow sensor Sensor for monitoring the total air flow in the pipe
system, i.e. checking the pipe system for blockage
and fracture; depending on the demands of the air
flow monitor →single-hole monitoring and the
detection of a fracture at the end of the pipe
system are possible.
Air sampling smoke detection system An active system producing under-pressure for air
sampling with a ventilator, integrated in the
system. The air samples are then passed to a
detection unit (smoke detector, detector head or
detector module).
Alarm a) Acoustic and/or optical signal activated
through →smoke detectors to indicate a fire.
b) Freely adjustable alarm threshold. The
activation of the alarm definitely means the
detection of a fire. The fire department is
informed.
Alarm condition The condition of a fire detection installation or a
part of it as a reaction to an existing danger.
Alarm current
An increased voltage in the →alarm condition
(→quiescent current).
Automatic smoke detectors These detect and analyse physical parameters
which lead to danger-warning signals. Automatic
smoke detectors are e.g. point-type detectors and
→air sampling smoke detection systems.
C
Central fire panel Central part of a fire detection installation which
supplies the detectors with power, displays
received signals optically and acoustically and, if
required, transmits them and checks the
installation for faults.
Collective detection systen Conventional line detection technology for which
all detectors, connected to the same line, have the
same collective address (common indication and
operation without identification of the individual
detector).
