Why do the ITI transmitters work backwards after they have been learned into the panel?
When learning ITI wireless transmitters into the system, the point must be in the faulted state prior to learning into the panel. Trip the tamper switch to learn the point.
Leaving the point in the normal condition while learning will cause its operation to become backwards. i.e. when normal it will behave as if it is faulted and when faulted it will behave as if it is normal.
