Description

• Triple infrared sensor

according to EN 54-10, Class 1

• Detection of open ﬂ ames through

ﬂ ickering infrared radiation

• Very high immunity to deceptive

alarms

• Selectable response delay
• Relay contacts for alarm and fault
• Integrated optical test function

The Flame Detector 16589 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:

• Pharmaceutical industry

• Paint shops

• Warehouses

• Nuclear facilities

• Tunnels

With three 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 particularly

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,

a built-in infrared source simulates 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.
