YBO-R-SCI Combined Short Circuit Isolator/Detector 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 can be fitted ( SR3T) to conceal the wiring connections. The device is also available as a DIN Rail mountable unit.
