The Hochiki YBO-R/SCI(RED) is a red short-circuit isolator base for the Hochiki ESP analogue addressable system, designed for the CHQ-WS2 wall sounder and CHQ-WSB2 wall sounder beacon. An amber LED shows when it is isolating a section of the loop. It does not use a loop address and wires the same way as the standard YBN-R/3 base, so it is simple to install.
