Clear of condensation
FFE’s Fireray optical beam smoke detectors provide wide area smoke detection when it is impractical to use traditional point-type detectors.
Lower temperatures can cause condensation to form on detector lenses and reflective prisms. This obscures the lens and prism, reducing the amount of infrared (IR) light reaching the detector. This has a similar effect to smoke and can lead to unwanted false alarms.
To combat this, FFE has developed a new range of anti-condensation heaters for its Fireray range of optical beam smoke detectors and reflective prisms. The detector heater circulates a current of warm air over the lens, raising its ambient temperature by up to 10°C and maintaining the lens at an incrementally higher temperature than the surrounding air. This dramatically reduces the likelihood of condensation forming on the lens.
