Dräger Flame 1500 (IR3)

​The Dräger Flame 1500 flame detector uses its triple IR sensor to detect hydrocarbon fires even at great distances. It offers you high reliability against false alarms.

Fast and reliable flame detection

​The Dräger Flame 1500 is equipped with three infrared sensors. They enable it to detect hydrocarbon-based fires even at a great distance. This reliability allows it to meet IEC 61508 requirements for safety integrity according to SIL2. The flame detector also has a HART® interfaces via which it can be connected directly to the fire alarm system, for example. In addition, the Flame 1500 has a low power consumption.

Prevention of false alarms

​The Flame 1500 measures infrared radiation in three different wavelengths and compares them with the reference value of CO2, which is produced during the combustion of hydrocarbons. In combination with the analysis of the flame's flickering, the complex algorithm identifies a fire and excludes sources of interference. In this way, the Flame 1500 reliably prevents false alarms caused by possible fault sources such as welding work or black body radiation.

Robust and resistant

​The powder-coated housing made of stainless steel or aluminum is very robust and weatherproof. The viewing window is heated to protect against icing and fogging. This allows you to operate the Flame 1500 reliably under a wide range of environmental conditions.

Simple check

​The Optical Verification Test (OVT) automatically checks the electronics and optics of the Flame 1500 without affecting the field of view. The three-colour LED on the front lets you quickly see the status of the unit. Green stands for normal operation, yellow indicates a fault and red signals a fire alarm.
