The B501BI detector base with an in-built isolator works with System Sensor analogue addressable detectors.
This particular isolator base prevents an entire communications loop from being disabled when a short circuit occurs.
This is achieved by isolating the loop segment containing the short, from the rest of the circuit.
When the cause of the short circuit is corrected, the isolator base automatically restores the entire loop.
