The YBO-R/SCI(WHT/SNDR) is a loop isolator fully compatible with Hochiki’s ESP analogue addressable protocol. It is designed for use with the white wall sounder (CHQ-WS2(WHT)) and white wall sounder beacon (CHQ-WSB2(WHT)).
The base features an amber LED that illuminates when a section of the loop is being isolated. The unit does not require an address and shares the same wiring configuration as the YBN-R/3 Sensor Base, making installation straightforward. The isolator can also be used without a sounder, with a SI-CAP cover available to conceal wiring connections.
