The output relay contacts are labeled in the un-powered alarm state.  The relay is energized
when the VRF-2000R is not alarmed.  This status may be opposite that of other Bindicator

®

brand units.  If the VRF-2000R is replacing an older Model RF unit, connections will need to
be opposite.  If a connection was made to NC1 terminal of the RF, connect now to the NO1 
terminal of the VRF-2000R.  C1 and C2 connections would remain the same.
