The FC410LI Line Isolator Module is designed to be used on the FireClass addressable loop control panel. It monitors the line condition and when detecting a short circuit will isolate the affected section whilst allowing the rest of the addressing circuit to function normally.

The purpose of the FC410LI Line Isolator Module is to ensure that, on a looped addressable system, no short circuit fault can disable more detection devices than would be lost on a conventional non-addressable fire circuit.

The FC430SAB is a FireClass Addressable Beacon that fits into the 5B Standard Base. Alternatively the FC430SAB may be fitted to the FC430SB, Sounder Base to enable the FireClass 500 Control Panel to communicate with and control this sounder bases and also provide a Flashing Beacon effectively turning the FC430SB into a combined addressable loop powered sounder and beacon.

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.
