Duct smoke detector
RM- O-VS-D
General
– To prevent smoke from spreading in buildings,
it is extremely important that the smoke
is detected at an early stage.
– Duct smoke detectors that operate
on the principle of light scattering detect
the smoke regardless of its temperature
so that the fire dampers can be closed before
the release temperature of 72 °C is reached
– If the air contains suspended particles,
as is the case with smoke, beams of light
are deflected off these. A sensor (photodiode),
which does not receive light in clear air,
is illuminated by the scattered light.
– The fire damper or smoke protection damper
blade is released when the brightness of the
scattered light exceeds a certain threshold
