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.
