The RK75B is a barrier(TX+RX) linear beam optical smoke detector for wall flush-mounting. The 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 transmitter towards the receiver. The RK75B 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 white smoke and black smoke too if it’s not very dense.
This detector is exspecially suitable for applications where the aesthetics element, the small dimensions, the possibility of remote control and the simplicity of use have a primary
importance. The most important types of environments where the RK70R
is usually installed are museums, churches, offices, hotelsetc.
