LOOPDRIVE

The Fault Isolator Module (FIM) is the successor in our range of loudspeaker loop-isolator devices that use our patented technology to deliver a higher level of availability of evacuation loudspeaker lines that are installed according to the return-loop principle. 

A loudspeaker failure in a faulty section between any two FIM’s in the loop is automatically detected and isolated in order to ensure maximum availability of the remaining loudspeakers on that same loop. The FIM protects the loop integrity against any open and wire-to-wire short circuits.

With Loopdrive  in quiescent mode. A maximum of 200 isolators are protecting the audio-transmission path. All zones are broadcasting the evacuation signal. When the audio-transmission path is affected by a hazard (such as a fire). Broadcast can be interrupted. All isolators take immediate action by isolating the damaged areas from the transmission path  and isolate the hazard. The Evacuation signal is still broadcast into the remaining areas of the zone.  

In less than 4 seconds the hazard has been detected and isolated from the transmission path and broadcast continues.
