Scope F-Link XP relay expansion unit for F-Link4 System, when any F-Link4 unit on the F-Link4 master network goes into fire or fault alarm, an individual relay output is triggered per event allowing individual events to be zoned on the main fire panel. For sites where it is also required to indicate on the Master fire control panel which remote F-Link node has gone into alarm, the F-LINK XP provides the solution.
