The System Sensor B524IEFT-1 isolator base is designed
for use with all System Sensor 200 analogue addressable
detectors. The B524IEFT isolator base prevents an entire
communications loop from being disabled when a short
circuit occurs. It achieves this by isolating the part of
the loop containing the short from the remainder of the
circuit. The base will automatically restore the entire loop
when the cause of the short circuit is corrected. Up to 20
devices may be isolated per isolator base, depending on
the device type.
