Dräger Flame 1700 Flame Detector

The Dräger Flame 1700 is an UV Flame Detector, designed for the detection of non-organic based fires such as hydrogen and metals as well as organic based fires. This Draeger Flame Detector provides flexibility with its numerous output modes, and advanced design features ensure reliability and speed in the detection of such fires.

Simple installation
The Dräger Flame 1700 is easily installed with a stainless steel mounting bracket; this can be rotated to ensure optimum positioning of the detector in relation to the potential fire source. Angular markings allow the positioning angles of the detector to be recorded for future reference.

Detector flexibility
As well as a 4 to 20 mA output and 3 relays, an optional RS 485 output is also available, which can be multi-dropped to a central location. This provides a number of options for detector monitoring and the
triggering of the necessary control action upon the detection of a fire.

Automatic and manual optics checks
Automatic checks of the detector electronics and optics ensure no fault goes undetected. Additionally the test can be triggered manually at any time.

Isolated 4 to 20 mA as standard
Complete flexibility enables the detector to be operated from a separate power supply (as a 4 wire device) or as a 3 wire device where there is no requirement for an isolated output.

Easily visible status LED
A tri-colored LED which is visible at the front of the Flame Detector provides a simple status indication to personnel in close proximity to the detector. Green indicates normal operation; yellow indicates a fault and red indicates the presence of radiation.
