Description
• UV sensor combined with dual IR
sensor, according to EN 54-10,
Class 1
• Detection of open fl ames through
fl ickering IR and UV radiation
• Highest immunity to deceptive alarms
• Selectable response delay
• Relay contacts for alarm and fault
• Integrated optical test function
The Flame Detector 16591 responds to the fl ickering
infrared and ultraviolet radiation of open fl ames. There-
fore, it is extremely 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:
• Aircraft hangars
• Power stations and turbine plants
• Military bases
• Nuclear facilities
• Fuel depots
Thanks to the combination of two independent infrared
sensors for different wavelengths and an UV sensor as
well as an intelligent evaluation logic, the detector can
distinguish particularly safely between alarm situations
and deceptive alarms. Therefore, it is very insensitive
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,
built-in infrared and ultraviolet light sources simulate a
fi re situation which activates the detector.
The detector has been designed for indoor and outdoor
use. The optional Detector Mounting Bracket 7127 al-
lows stepless horizontal and vertical adjustment for the
easy adaptation of the detector to the required monito-
ring area.
For use in explosion-hazardous areas, an Ex version of
the fl ame detector is available on request.
