The OSID linear smoke imaging detector uses a sophisticated pixel-level mathematical evaluation algorithm to compare the infrared (IR) and ultraviolet (UV) gray levels on pixel level in the CMOS imager.
The multi-emitter imager will analyze the signals from up to 7 emitters.
The system uses dual wavelengths so that different particle sizes can be detected and distinguished. While there is a strong interaction between the shorter UV waves for both small and large particles, the longer IR waves are only affected by larger particles.
Through the algorithmic evaluation of the attenuation of both wavelengths, the detector is able to distinguish large dust particles from smoke, building movements and entering solid bodies as possible making the detector highly resistant to nuisance alarms.
3D volumetric coverage
Receivers with a viewing angle of 80° have an imaging chip that allows up to seven transmitters per receiver. Unlike conventional linear detectors, where each receiver must be wired, only the wiring of the receiver is necessary here.
Since the different transmitters can be easily adapted to obstacles along the walls and arranged at different heights, an optimum coverage achieved. The beam length of the 80°-imager ranges from 8 to 150 m. The horizontal and vertical viewing angles of the receivers allow 3D coverage.
Furthermore, optical filtering, high-speed image acquisition and intelligent software algorithms ensure that the detector processes images and thus ultimately offers the highest possible degree of stability and sensitivity, while at the same time offering greater insensitivity to extreme lighting fluctuations.
The OSID detector (receiver) has an internal event memory for up to 10.000 events for possible alarm and fault analysis.
The connection to the esserbus loop is made in the usual way via the esserbus transponder. It is also easy to reset using this esserbus transponder by programming the relays on it as reset relays using the tools 8000 programming and service software and setting the reset time individually.
