Dräger Flame 2370 UV & IR Flame Detector

The Dräger Flame 2370 is a UV & IR Flame Detector, with an extremely short response time and very high reliability against false alarms. The Dräger 2370 can quickly and reliably detect hydrocarbon and hydrogen based fires, as well as hydroxyl flames and fires resulting from metallic or inorganic materials. The Draeger 2370 Flame Detector is able to detect a fire flash in less than 20 milliseconds.

Very fast and reliable detection
The Dräger Flame 2370 Flame Detector combines very sensitive UV und IR sensors. It is quick and reliable in detecting hydrocarbon- and hydrogen-based fires, as well as hydroxyl flames, and fires resulting from metallic or inorganic materials – fire flashes and explosions are detected in less than 20 milliseconds. This degree of reliability complies with the IEC 61508 safety integrity requirements of SIL2. Moreover, the Dräger Flame 2370 has HART® and RS-485 Modbus interfaces and requires very little power.

Prevention of false alarms
The 2 sensors incorporated in the Dräger Flame 2370 offer detection in the shortwave UV range and in the IR spectrum. Frequency, intensity and duration of the measuring signals are analyzed. An alarm is set off only when both sensors meet the reaction criteria. This way the Draeger Flame 2370 Flame Detector prevents false alarms. Moreover, the sensitive detection ensures that this Flame Detector does not falsely set off an alarm for fires emanating from other areas.

Robust and resistant
The housing of the Dräger Flame 2370 Flame Detector is very resilient and weatherproof. The viewing window is heated to protect it from icing and fogging up. This allows you to operate the Dräger Flame 2370 reliably under the most diverse environmental conditions.

Simple check
The Built-in-Test (BIT) automatically checks the electronics and the optics of the Dräger Flame 2370. You can also perform the check manually. A tri-colored LED at the front of this Flame Detector provides a quick status indication. Green indicates normal operation, yellow indicates a fault and red indicates a fire alarm.
