016519 Flame detector flameproof Ex d, IR3
u Suitable for explosive areas of the zones 1, 21, 2
and 22 (ATEX and IECEx certified)
u Sensitivity according to EN 54-10 Class 1: 0.1 m²
flames at 25m
u Low risk of false alarms due to different IR
wavelengths and a combination of filters and
signal processing techniques
Flame detectors are used to detect open flames
indoor and outdoor. They respond to the light emitted
from flames during combustion.
Flame detectors are especially suitable for smokeless
liquid and gas fires not visible for the naked eye as
well as for fires of materials that contain carbon with
strong smoke emission.
Typical areas of application are large industrial
warehouses, airplane hangars, chemical facilities, oil
refineries, machine rooms, ferries and freight ships,
power plants, printing plants, wood warehouses,
subway tunnels.
Flameproof equipment is contained in an enclosure so
strong that an internal explosion will neither damage
the enclosure nor be transmitted outside of it. The
surface remains cool enough not to ignite the
explosive mixture.
u Reliable operation, even if the lens is
contaminated by a layer of oil, dust, watervapour, or ice
u Selectable response time
u 2-wire or 4-wire configuration via DIP switch
settings

Functions
Most IR flame sensors respond to 4.3 µm light,
emitted by hydrocarbon flames. By responding to 0.75
to 2.7 µm light emissions from fires almost all
flickering flames can be detected.
The flame detector has three IR sensors. The detector
discriminates between flames and other light sources
by responding only to particular optical wavelengths
and flame flicker frequencies. False alarms due to
factors as flickering sunlight are avoided by a
combination of filters and signal processing
techniques. Low-frequency detection enables the
sensor to operate through a layer of oil, dust, water
vapour, or ice.
An alarm is transmitted via current amplification (2wire) or relay contact (4-wire). The alarm is also
indicated with the integrated alarm LED.

Installation/configuration notes
• The device complies with EN 54-10 Class 1.
• Applications and locations to avoid:
– ambient temperatures above +55 °C
– close proximity to radio frequency sources
– exposure to severe rain and ice
– large amounts of flickering reflections
– large IR sources for instance heaters, burners,
flares
– obstructions to field of view
– sunlight falling directly on the detector optics
– spot lighting directly on the detector optics
• Latching mode is recommended (factory setting).
Different alarm signalling modes can be set via DIP
switches: current amplification (for 2-wire
configuration) or relay contact (for 4-wire
configuration).
• The device can be connected using an FLM-420/4CON Conventional Interface Module to the Local
Security Network LSN. The device can also be used
in conjunction with a CZM 0004 A module. For
connecting more than one IR3 Flame Detector use a
four-wire connection with end of line element.
Extended line monitoring is necessary for EN 54-13
compliant operation.
