Fire Control Systems
With all the features of the 5B Universal Base the FC450IB Isolator Base allows any FC400 Series Detectors to be upgraded to incorporate bidirectional short circuit isolation.

Implemented on every detector, the FC450IB can ensure that no detector is lost on a system in the event of an open or short circuit.

Alternatively, the FC450IB can be implemented between detectors to provide short circuit isolation according to EN54.

The FC450IB can be used as a stand alone line isolator fitted between call points and other ancillaries.
