Safe and economical

Three detection principlesaswellasthe integrated
microprocessor allow the detection offiresattheir
earlieststage.
Far beyond the applicable regulations, the multi-
sensor detector thusguaranteesan optimum ofsafety.
The microprocessor differentiatesbetween fire-related
and disturbance-related parametersand reliablypre-
ventsfalse alarms. Despite increased safetythe multi-
sensor detector isnotmuch more expensive than a
single-sensor detector.
The ongoing self-diagnosisdelivershigh operational
safetywith low maintenance expenses. And ifthe object
isto be used for other purposes, the conversionsother-
wise necessary, which are often verycostly, willnotbe
required.

Everysecond counts

Even todaya fire isan incalculable quantity. External
environmentalconditionssuch asopen windowsand
the qualityofthe burning materialssuch aswooden or
syntheticmaterialsdetermine the progressand the speed
ofspreading. The earlier a fire isdetected, the faster itcan
be controlled. And the damage to personsand property
willbe accordinglylower.
Therefore the earlyand reliable detection ofa fire
bymeansofsuitable detectorsisa top priorityin fire
protection.
The material and energycomposition is
differentwith each burning material and
fire progress; therefore differentdetec-
tion principlesare required.

Everyfire isdifferent
l
The productsofcombustion arising with a fire are
the crucialcriteria for fire detection. Opticaldetectors
detectvisible smoke particlesasproduced in the
smouldering stage ofPVC. Thermaldetectorsdetect
open, quicklyprogressing firessuch asfiresofliquids.
And ionisation detectorsregister dark, finestsmoke
particlesaswellasthe invisible aerosols, which
develop with firesofsyntheticmaterials.
Thatmeans: everysingle sensor hasa detection
spectrum, in which itworksoptimally. However, due to
the differentcomposition ofthe materialsapplied in
objectsitcannotbe predicted which productsofcom-
bustion have to be detected in case ofemergency.

Multi-sensor technology
Highestsafetyfor allcases
l
The patented multi-sensor detector combinesthree
detection principlesin one detector. The correlation of
optical, thermaland ionisation-based sensorsensures
thatallfire typesare detected reliably. The integrated
microprocessor automaticallyanalysesthe fire param-
etersofthe single sensors. Fireswillbe detected earlier
and more reliablyand differentiated from disturbance
parameters, which preventsfalse alarms. Long-term
processessuch aspollution and ageing are detected
and compensated for bythe multi-sensor detector.
Technological advantage in detail: bycombining the three
detection principlesall productsof combustion are detected
asearlyaspossible and reliably.
The microprocessorbundlesthe
variousinformation and communi-
cateswith the central fire alarm
system.
The multi-sensordetectorhasa timelessand elegantdesign.
