NSC Sicherheitstechnik B02700-00 Discovery Optical Smoke Detector
With a white moulded polycarbonate case, the NSC Sicherheitstechnik Discovery Optical Detector features wind-resistant smoke inlets. The LED indicator is red when in alarm but remains colourless when the detector is in a quiescent state.
Within the case is a printed circuit board
which, on one side, has the light-proof
chamber with integral gauze surrounding
the optical measuring system and, on
the other, the signal processing and
An infra-red light emitting diode within its
collimator is arranged at an obtuse angle
to the photo-diode. The photo-diode has
an integral daylight-blocking filter (Fig.2).
The IR LED emits a burst of collimated
light every second. In clear air the photodiode
receives no light directly from the IR
LED, because of the angular arrangement
and the chamber baffles.
enters the chamber it scatters light from
the emitter IR LED onto the photo-diode
in an amount related to the smoke
characteristics and density. The photodiode
signal is processed to provide an
analogue value for transmission when the
detector is interrogated.
