ABSTRACT:
A system which utilizes optic fibers for the transmission of light from a process measuring device to an alarm actuating circuit is disclosed. An optic fiber (14) is positioned adjacent each process monitoring location and transmits light therefrom to a remotely located matte screen (12) from which it is reflected to a pair of optic fibers (16, 18). The optic fibers (16, 18) transmit the light of optic diodes (20, 22), respectively, which are selectively actuated in response to the color of the light being transmitted and which, in turn, selectively actuate an alarm circuit connected thereto.
