The RK90-R it’s a reflection Beam Smoke Detector. Its operation
is based on the relation between the smoke present in an
environment, generated by the starting of a fire, and the infrared
beam emitted by the device and reflected by a special optical
reflector. It is also able to detect the presence of vapour and fog.
A fundamental feature of this detector is the ability to detect the
presence of both white smoke and black smoke even if they are
little dense.
This detector has been designed for applications where the
aesthetics, the small dimensions, the possibility of remote
visualization of the signal and the simplicity of use have primary
importance.
So RK90-R is particularly suitable to be installed in artistic
environments like museums, churches, art galleries and in offices,
hotels etc.
