Description

The Flame Detector 16581 responds to the fl ickering
infrared radiation of open fl ames. Therefore, it is extre-
mely well suitable for the detection of fi res which are
diffi cult to detect with common smoke detectors – for
example, alcoholic fi res or gas fl ames.
The detector is ideal for the following applications:
• Aviation and automotive industry
• Paint shops
• Warehouses
• Textile industry
• Waste treatment
With two independent infrared sensors for different
wavelengths and with an intelligent evaluation logic, the
detector can safely distinguish between alarm situati-
ons and deceptive alarms. Therefore, it is very insensiti-
ve to disturbance sources such as sunlight, fl uorescent
lamps or electric arcs.
The detector complies with EN 54-10, Class 1, which
means it is suitable to detect fl ames up to a distance
of 25m.
The response delay of the detector can be selected in
4 steps between 1 and 8s. An alarm and a fault conditi-
on is signalled via two dry relay contacts. Conventional
technology is used for alarm transmission to the fi re
detection control panel. The detector can be integra-
ted into an ADM loop by means of a conventional zone
module.
A simple test of the detector can be carried out by
means of the integrated optical self test function, which
does not require additional tools. During this self test,
a built-in infrared source simulates a fi re situation which
activates the detector.
The detector has been designed for indoor use. The op-
tional Detector Mounting Bracket 7127 allows stepless
horizontal and vertical adjustment for the easy adaptati-
on of the detector to the required monitoring area.
For use in explosion-hazardous areas, an Ex version of
the fl ame detector is available on request.
