The Hochiki YBO-R/SCI(WHT/SNDR) is a white short-circuit isolator base for the Hochiki ESP analogue addressable protocol, colour-matched for use with the white CHQ-WS2 wall sounder and CHQ-WSB2 wall sounder beacon. It detects and isolates short circuits on the loop, with an amber LED to show when it is isolating. It does not use a loop address and has the same wiring configuration as the standard YBN-R/3 base, so it is simple to install.
