Nominated for GIT SECURITY AWARD 2011:

Bosch Security Systems is extending its 420 Series of automatic fire detectors with three new variants offering enhanced smoke detection meeting all likely application requirements. The new variants feature Bosch’s innovative Dual Ray technology. This makes use of a dual-optical sensor that relies on the scattering of light emitted by two LEDs with different wavelengths to measure smoke density and particle size. This enables the detectors to provide even more reliable differentiation between smoke particles and other particles.

The dual-optical FAP-DO 420 detects test fire TF1 without using a multi sensor detector. Like the original four detectors, the new variants feature Bosch’s powerful ISP (Intelligent Signal Processing) technology, through which all sensor signals are pre-processed continually by dedicated internal evaluation electronics, analyzed and linked with each other via a built-in microprocessor. This ensures best-in-class differentiation between real fires and disturbances.
