YBO-R/SCI

Short Circuit Isolator Base

Model YBO-R/SCI is a Loop Isolator, which is fully compatible with Hochiki’s ESP analogue addressable protocol.

 

The YBO-R/SCI Base is compatible with any of the ESP Sensors, and can be used instead of the standard YBN-R/3 Base, this reduces the cost of the Short Circuit Isolators and improves the functionality. The Base incorporates an amber LED to show when it is isolating a section of the loop, and if used under every analogue Sensor on the loop, none would be lost if a single short circuit was to occur. 

 

The YBO-R/SCI does not use an address, and has the same wiring configuration as the YBN-R/3 Sensor Base making it very simple to install. The YBO-R/SCI can also be used without a Sensor; a cover (SI-CAP) can be fitted to conceal the wiring connections
