Bosch Security Systems launched its Automatic Fire Detector 440 Series of analog addressable devices. Consisting of seven detectors and four bases, the 440 Series includes detectors with photoelectric, heat and carbon monoxide sensors for increased reliability and reduced false alarms. Designed with Bosch’s Dual Ray Technology, the devices use two LEDs (one infrared and one blue) to scatter light, then compare the intensity of the different wavelengths to determine smoke density and particle size. Each detector features intelligent signal processing, which ensures that the sensor pattern matches that of an actual fire to protect against false alarms. The 440 Series also benefits from a self-monitoring feature that sends a trouble message back to the panel if sensor functionality cannot be detected.
