Siemens FDF241-9 3-Sensor Infrared Flame Detector

The FDF241-9 is a flame detector with three infrared sensors. Because it detects flame's own radiation before smoke reaches the ceiling, it is used in high-ceiling spaces and areas with intense air movement where point detectors are ineffective. ASA technology distinguishes flame from false sources such as sunlight, hot engines, and radiation. It is suitable for industrial warehouses, aircraft hangars, and underground tunnels.
