Fairport, US – Bosch Security Systems has launched the Automatic Fire Detector 440 Series of analog addressable devices. The new series, consisting of seven detectors and four bases, includes detectors with photoelectric, heat and carbon monoxide sensors for maximum reliability and reduced false alarms.
The detectors are also designed with Bosch’s powerful Dual Ray Technology, which provides extremely reliable fire detection. The technology’s dual-optical sensor uses two LEDs (one infrared and one blue) to scatter light. The detector compares the intensity of the different wavelengths to determine smoke density and particle size. This allows it to differentiate between smoke particles and other particles – such as dust or steam – that can cause false alarms in other detectors.
