Detectors – 600 Series

These detectors react to the whole
range of fire products from slow
smouldering fires, producing visible
particles to open flaming fires
producing large numbers of very hot
smaller sized aerosols. It combines
optical and heat detector technology
to detect clear burning fire products
which hitherto could only be easily
detected by ion-chamber detectors.
For normal ambient conditions, the
high performance optical detector
behaves as a normal optical detector.
Only when a rapid rise in temperature
is detected does the sensitivity of the
detector increase and the presence
of smoke will confirm a fire condition.
The HPO will not operate on a rate of
rise of temperature alone.
