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.

 Features

• Low current consumption: 100µA
• Complete isolation of short-circuit cable between isolators
• Automatic restore when short-circuit is corrected
• Rugged industrial design
• Loop positive (+ve) isolation
• Remote LED connection
• Sensor continues to operate with a short-circuit on either side of the isolator base
• Up to 40 devices may be isolated per isolator base, depending on the device type
